SCUBAPRO Sunday – Gunners Mate First Class Ingram WWI  

Sunday, October 16th, 2022

Gunners Mate First Class GM1 Osmond Kelly Ingram of Pratt City, Alabama, was the first enlisted man to die in World War I. On 15 October 1917, the 30-year-old seaman was serving aboard the Navy destroyer USS Cassin DD-43, which was sunk by a German submarine U-61. For his bravery that day, Ingram would be awarded the Medal of Honor. He would also be the first enlisted man to have a ship named after him.

Osmond Ingram was born in Oneonta, Blount County, Alabama, on 7 August 1887, to Naomi [Bettie] and Robert Ingram. His father was a Confederate Army soldier and Methodist Episcopal priest. Before Robert’s death in 1897, the family relocated to Pratt City, Jefferson County, Alabama. After becoming 16 years old in 1903, Kelly, as he was known, decided to join the Navy. On 24 November 1903, he enlisted in the United States Navy with his mother’s permission. He left the Navy after five years to join the Pratt City Fire Department. He spent five years as a firefighter before reenlisting in the Navy. As a Gunner’s Mate in the Gunnery Department, he was assigned to the USS Cassin. When the United States entered the war on 6 April 1917, Ingram was still aboard the USS Cassin. His ship was part of a Navy armada going to France and England to safeguard American commercial ships transporting merchandise.

The USS Cassin was patrolling off the coast of Ireland on 15 October 1917 when she came in contact with the German submarine U-61, which fired a torpedo. Ingram was the first person on board the destroyer to notice the torpedo heading straight for the ship’s stern. When Ingram realized the depth charges were kept in the stern, he dashed to the back of the ship and began releasing them to lessen the blast’s impact. Before the torpedo hit, he had detonated many of the depth charges. Ingram was thrown overboard from the explosion, and Cassin’s rudder was severely damaged. The warship was able to return to port for repairs. Ingram’s death was the lone fatality. His remains were never found.

In 1920, Secretary of the Navy Josephus Daniels wrote to his mother, notifying her of the decision to award Ingram the Medal of Honor posthumously:

“For extraordinary heroism in the presence of the enemy on the occasion of the torpedoing of the Cassin, on 15 October 1917. While the Cassin was searching for the submarine, Ingram sighted the torpedo coming and, realizing that it might strike the ship aft in the vicinity of the depth charges, ran aft with the intention of releasing the depth charges before the torpedo could reach the Cassin. The torpedo struck the ship before he could accomplish his purpose, and Ingram was killed by the explosion. The depth charges exploded immediately afterward. His life was sacrificed in an attempt to save the ship and his shipmates, as the damage to the ship would have been much less if he had been able to release the depth charges.”

After Congress established the Military and Naval Insurance Act in 1918, his mother became the first beneficiary of money for dependents of soldiers and sailors. The USS Osmond Ingram DD-255, a destroyer, was commissioned in June 1919 in his honor. It was the first navy ship to be named after an Enlisted sailor. The ship was one of the ships anchored at Pearl Harbor on 7 December, 1941.

SCUBAPRO Sunday – The Untold Story of the USS Cole Salvage Divers

Sunday, October 9th, 2022

Salvage divers of the USS Cole, the untold story of the Navy Divers who recovered fallen, help save the ship.

On the morning of Oct. 13, 2000, Chief Warrant Officer Frank Perna and his team of US Navy divers were sipping cappuccinos at an open-air coffee shop, enjoying a beautiful Italian morning in the Port of Bari, when the distinct ringtone of Perna’s cell phone cut the casual banter and light mood.

The divers, deployed with Detachment Alpha of Mobile Diving and Salvage Unit 2 aboard the USNS Mohawk, turned their attention to their officer in charge as he picked up the phone and listened intently. Mike Shields, now a retired master chief master diver, could tell the call was serious.

“I understand,” Perna said into the phone before hanging up. “We will be ready.”

Less than 24 hours earlier, the USS Cole, a US Navy guided-missile destroyer, was docked in Yemen’s Aden harbor for a planned refueling when al Qaeda suicide bombers in a small boat packed with at least 400 pounds of explosives steered their craft into the Cole’s left side. The blast ripped a 1,600-square-foot hole in its hull, killing 17 American sailors and wounding 39.

A skilled diver with extensive experience in underwater salvage and recovery operations, Perna had worked on several high-profile dive operations. He participated in salvage and recovery operations for Trans World Airlines Flight 800 and the USS Arthur W. Radford after its collision at sea with a Saudi Arabian container vessel.

Perna looked up at his team, who stared back with anticipation.

“The USS Cole was damaged from an explosion while in port,” he told them. “We are going to Yemen to assist the crew in recovery and salvage of the ship.”

The 12 men who composed Detachment Alpha launched into planning and preparing for a daunting mission: They would locate missing sailors, assist in stabilizing the ship, recover evidence, and perform structural inspections of the Cole after a terrorist attack.

“We immediately started pulling resources and gear to support several different diving and salvage scenarios,” Shields told Coffee or Die Magazine recently. “Because we were going to be somewhat isolated in Yemen, we knew everything we brought had to serve several purposes.”

The next day, the hand-picked team of Navy divers landed in Yemen with all the necessary dive systems to support the numerous planned and unplanned tasks of diving into and under a critically damaged ship. They loaded their gear onto two flatbed trucks and departed the airport with a sketchy Yemeni military escort. As they passed through several military checkpoints, Perna and his team began to feel the gravity of the situation.

When they arrived at the port, most of the team went to work setting up gear and readying a dive site near the ship while Perna and his senior leaders went to assess the damage. The sight shocked them. The ship was blackened by the explosion, listing slightly to the left, and without electrical power. The only light was from the green glow of the pier lights.

“Our first glimpse of the ship that night will be forever fixed in our minds,” Perna told Coffee or Die.

As Shields took in the damage and saw the Cole’s battle-weary crew members sleeping on mattresses scattered randomly on the ship’s weather decks, his shock turned into determination.

“Get in the water,” he thought. “Get the Cole back.”

On the morning of Oct. 15, 2000, the divers began the first phase of their mission. Several sailors were still missing in the flooded spaces below, and the men of Alpha Detachment had to get them out and repair or salvage what they could as soon as possible.

With flooding in the ship still posing a significant threat to electrical and engineering spaces, time was not on Alpha’s side. They determined which areas of the ship to search, identified a centralized location to set up a dive station, and planned how to safely enter the spaces they needed to reach. They boarded the Cole, set up gear, and began diving from inside the flooded spaces.

With the utmost care and respect, the Navy divers recovered missing Cole sailors. When a sailor was recovered, the divers paused their work to observe a moment of silence and honor the dead. They draped a flag over each fallen soul and escorted them down the pier to be taken back home.

“It’s a very heavy feeling in your heart to see one of your own covered in the flag,” Perna said. “It’s hard to check your emotions and refocus attention back to the task at hand, but you’ve got to push it back down because we’re doing a dangerous job.”

In addition to recovering the fallen, Alpha had to stop the flooding into the only engine room that was still operational. Reaching the damaged area required navigating through 50 feet of razor-sharp mangled steel, reduced visibility, and a thick layer of engine fuel building on the surface of the water. To get in and out of the water, the Navy divers had to travel through a layer of oil that they worried might catch fire if something sparked. The team deployed a fire retardant over the surface as a preventive measure.

Shields, who was familiar with the layout of the Cole from conducting routine maintenance on the ship the previous year, was one of two divers who suited up, went below the surface through an auxiliary shaft, and made their way slowly to the engine room. They couldn’t see anything and kept bumping into loose gear and debris floating around the spaces.

Making things even worse, the divers’ life-giving tether lines of air, communication, and light power — their “umbilicals” — were constantly hanging up or snagging on unknown obstructions. With every valuable foot gained, the divers had to stop to free themselves.

“We were blindly feeling around for landmarks that would take us to where we thought the flooding was coming from,” Shields recalled.

Using memories of what the engine room would have looked like, Shields and his dive buddy felt around and found landmarks to orient themselves by, eventually finding the cause of the flooding. They filled it with a 3-inch braided ship’s mooring line covered in a thick layer of electrical putty.

“We filled in the crack and effectively stopped all flooding,” Shields said.

Stopping the flooding saved the ship from sinking and prevented what could have been a total loss.

The next day, the Cole’s diesel generator stopped running, and members of the dive team had to locate and secure the damaged piping and reroute pressure through alternate channels back to the generators. Navigating underwater in the damaged area again proved challenging. Bulkheads were blown inward, all non-watertight doors had broken from their hinges, filing cabinets lay scattered across the deck, and visibility was reduced to less than 3 inches.

The Navy divers spent a lot of time rerouting valves controlling pressure, fuel, oil, or air to their secondary and tertiary systems to help offset the ship’s left-side listing. With the major flooding stopped and the Cole stable, the team focused on reviewing and assessing the massive opening the blast had ripped in the left side of the ship’s hull.

“It was nothing less than devastating,” Perna said. “The most disturbing sight was the extensive damage inside the ship. The blast from the explosion had torn 30-35 feet into the center of the ship.”

The explosion was so powerful that the deck had blown upward and fused onto the bulkhead where an office once sat. Crew members who’d been eating on the mess decks reported that the blast’s power created a visible wave that traveled across the deck.

The divers created a staging area just aft of the blast area on the Cole’s left side so they could easily access the outside space and assist the FBI and several other agencies in gathering information and documenting evidence for future investigations.

Outfitted with thick rubber wetsuits, dive knives, and iconic yellow Kirby Morgan MK 21 diving helmets, divers splashed into the hot Persian Gulf water and entered the blast area.

“Everything was surreal about diving on board and into a ship with an extensive hole in the side of its hull,” Perna said. “The fact that you can dive inside the ship, turn around, and see the sunlight cascading into the enormous space is beyond explanation.”

On Oct. 17, 2000, Navy divers prepared to search the flooded main engine room, which suffered extensive damage in the blast and was essentially a total loss. Confirming primary and secondary routes with engineers and the crew, Perna and his team devised a plan to move through the ship’s ventilation-shaft system to access the previously unreachable space.

Before entering the cramped shaft, divers wrapped fire hoses around their umbilicals for protection, modified their gear to slim down their profiles, and slipped into wetsuits to protect themselves from the environmental hazards of fuel, oil, and razor-blade-like steel. The divers inched their way to the main engine room, a feat Perna and Shields likened to John McClane crawling through the ventilation shafts of Nakatomi Plaza in Die Hard.

Watching closed-circuit video systems, engineers from the Cole and the USS Donald Cook guided the Navy divers as they moved through sheared bulkheads, buckled decks, broken pipes, and wires that created an immense “spider web” of destruction. Metal shavings sparkled as the divers’ lights scanned the engine room.

“We could feel the change in densities between fuel and water,” Perna recalled. “Everything fouled our umbilicals in the engine room. Pieces of broken equipment fell from the overhead as we disturbed their delicate balance.”

In that unforgiving, stifling space, the men of Detachment Alpha recovered three more missing sailors.

Over the following 10 days, from Oct. 18 through Oct. 28, the Navy divers recovered personal items from the flooded spaces and sifted through the fine sand on the seafloor for anything that might have belonged to the fallen. They searched every flooded compartment, including areas deemed too dangerous to enter safely, recovering all remaining missing sailors and assisting FBI investigators in collecting evidence. The divers inspected every inch of the blast area, looking for evidence of the explosive device. The FBI was keenly interested in anything that might help its investigation to identify the terrorists or the composition of the bomb.

The Navy divers also worked to mend damaged areas of the Cole and helped prepare the ship for its journey back to the United States. They relieved pressure in the main structural supports by drilling holes at the ends of the significant cracks, alleviating stress and preventing the damage from spreading. Once the necessary repairs were made, the team prepped the ship for a journey out to sea.

The challenge was to keep the ship from listing over to the left side. The Cole’s crew worried that the repairs made to stop the flooding might be damaged once in the open ocean.

“We had the idea to hedge our bets and have some contingencies in place if something happened,” Shields said.

They ran several hydraulic pumps to the critical spaces and had discharge lines over the side in case a space started to fill with water.

On Oct. 29, the USS Cole slowly moved away from the pier with a small crew aboard to monitor the ship. Supported by tugboats and a tow line from the USNS Catawba, the Cole made the journey from the coast of Yemen to the MV Blue Marlin, a 700-foot-long Norwegian heavy-lift transport ship 23 miles out at sea.

When the Cole reached the Blue Marlin, the Blue Marlin partially submerged its lower deck and floated it under the damaged Cole. Once in place, the ship slowly rose to the surface, gently lifting the Cole from the ocean and resting the mighty ship on the Blue Marlin’s deck.

With the Cole on the Blue Marlin, Shields and his divers checked the ship for flooding once more and found that their work had held. Shields gave the thumbs-up to higher, climbed the side railing, and dove into the ocean, swimming back to his team on the Catawba.

The entire docking evolution took nearly 24 hours to complete. With the Cole securely aboard the Blue Marlin’s deck, they made the trip back to the United States.

The Navy divers’ contributions were instrumental, Perna said. In a small amount of time, the team got the diesel generator back online, rerouted the ship’s air system, set up and operated emergency dewatering equipment, and provided air recharging service to the FBI and explosive ordnance disposal divers.

“No one person can accomplish them alone,” Perna said. “I was grateful to have such a fine and experienced diving and salvage team. I am indebted to and extremely proud of the divers in Detachment Alpha who made it all possible.”

The Detachment Alpha divers safely conducted 37 dives with more than 76 hours of subsurface work during the Cole operation. The ship was fully restored to service within 18 months of the attack in Yemen. The men of Detachment Alpha played a vital role in the operation that ensured the USS Cole’s ability to sail freely today.

SCUABPRO Sunday – Common Dive Skills

Sunday, October 2nd, 2022

Training like you fight doesn’t just mean having your body armor on when you are on the range, and you should always practice basic skills whenever you get in the water. The best way to become a better diver is to practice and improve on the basic skills constantly. Here are some basic skills you should practice every time you get in the water.

Buoyancy

This is one of the most critical skills for every diver to master. Mastering buoyancy is not necessarily a difficult task, but it requires a calm, focused mind, and practice. You will consume less air when your buoyancy is on point, and you will not risk shooting to the surface and giving yourself away or, worse, getting injured. To practice your buoyancy, try and be a couple of feet off the bottom of the pool using a body positions simulation to sky diving. Try maintaining the same distance from the bottom and now just using your fins spin to your left, then spin to your right, again holding your positions. Now once you have that, try, and move backward, besides just using your fins. This will help you with moving in confined spaces and around piers.

Descents

The descent should always be performed slowly and controlled. You will need to equalize the pressure in your ears as you descend constantly; that can mean every 12-18 inches 30-40cm for some divers. Descending too quickly can cause your eardrums to rupture, which can lead to more severe complications. A slow descent will also prevent silting on the bottom, which will decrease visibility. Also, practice your emergency descents. It will be the same as before but faster.

Clearing Your Mask

At some point, you will get water in your mask. So, it is better to practice in a controlled environment than to have not done it a long time and try and remembered when it is the middle of the night in someplace where you don’t want the water touching your face. If you have water in your mask, follow the clearing techniques you learned in your training. If you need to stop momentarily, alert your buddy so you do not get separated. You should be able to master this essential skill without having to stop. It would help if you also did this, allowing as a minimal number of bubbles as possible. Make sure you practice this when you are learning to use any diver propulsion vehicle.

Emergency Ascent

It is no different than practicing a down man drill.  Well, other than the fact that you are in the water. Your emergency ascent may require that you share air with your buddy, swim in a controlled manner to the surface, you might have to drop your or their weights. I have had to do this when my dive buddy passed out, and I was so freaked out I didn’t have to drop anything to get him to the surface. It was also my first dive in the teams, and I thought he was dead Practice all types of emergency ascent techniques whenever possible to not panic when a real emergency occurs.

Hand Signals

Once you start diving with someone, you might come up with some hand signals of your own, like you have your head up, you’re a$$. But the essential hand signals will be used by everyone worldwide. You never know when you will be diving with someone from a partner nation, and that is all you have to go by. So, knowing the basics will help.

Going Up or Down

Use a thumbs-up signal to indicate that you are going up or a thumbs down to indicate the opposite.

I’m OK

Place your thumb and forefinger together, forming a circle, and leave the other three fingers extended upright. This is the same as you would say, OK, as you would above water.

Stop

Signal your dive buddy to stop by holding up one hand, the same as you would in any other instance. You can also use a closed fist like being on patrol.

Changing Direction

Just like with up and down, point your thumb (or your index finger) to indicate which direction you’re heading. You can tell again like on land.

Turn Around

To let everyone know it’s time to turn around, put your index finger up and rotate in a circle. Similar to rally-up.

Slow Down

Place your hand in front of you with your palm facing down. Wave your hand up and down to indicate that you need everyone to slow down a bit.

Level Off

To indicate that you want to level off once you’ve reached a certain depth, put your hand out in front of you, palm down, and wave it back and forth.

Something’s Wrong

Place your hand out in front of you, fingers spread and palm down. Wave your hand back and forth in a rocking motion. It is similar to the hand signal, maybe.

Help!

Wave your entire arm from outstretched by your side to over your head. Repeat the motion as long as you need to.

How much air do you have?

With the forefinger and middle finger hit in the palm of your hand to ask your buddy how much air is left in the tank. The usual response is in numbers.

I’m Low on Air

It takes practice to be able to make your air last. Clench your hand into a fist and pull it in toward your chest. Repeat as much as you need to indicate how urgently you need to resurface. When diving a rebreather, you should point at the pressure gauge. With some of the newer rebreathers, you can pull your gauge out and show it to your dive buddy if needed.  

I’m Out of Air

Suppose something has gone wrong with your equipment, signal quickly and repeatedly. Place your hand, palm down in front of your throat, and move back and forth in a cutting motion.

SCUBAPRO Sunday – Wetsuit Care

Sunday, September 25th, 2022

Your wetsuit is an essential part of your dive gear, as it protects your body from heat loss, abrasions, and wildlife injuries on a dive. Without proper care, neoprene can be damaged easily when you’re not even diving. Although they are designed to last a long time, certain elements will destroy it, if you don’t take care of it. Here are a few things that will damage neoprene. This stuff will also damage your H-gear/ Armor carrier and other nylon equipment.

Sunlight

Sunlight is one of the worst things for any nylon product. You never want to leave your wetsuit hanging in direct sunlight to dry. Neoprene takes a beating from UV radiation, and it will begin to break it down quickly. Paired with heat, it can break a new wetsuit down in a matter of months.

Heat

Even in the absence of sunlight, heat is not good for neoprene. Under no circumstances should you ever put neoprene in the dryer. Even leaving it in a hot car can begin the process of deterioration. The best way to dry your wetsuit (after a fresh water rinse, of course!) is to hang it in the open air, in the shade. So, try not to store your wetsuit in a Conex box.

Salt and Minerals

If you’ve been diving in the ocean, you’ll need to rinse your wetsuit immediately with fresh water so that the salt, minerals, and bacteria accumulated during the dive will not remain to crystallize and produce odors. Soaking it in a tub is the best way to do this. Do more than just rinse it with a hose and hang it up to dry. Even if you haven’t exposed your wetsuit to any of the other damaging elements in this post, a stinky, bacteria-laden wetsuit is just as ruined if you never rinse it. Occasional soakings with a product like Sink the Stink are a great way to refresh your wetsuit every few weeks or months, depending on how often you dive. Also don’t think “oh I just used it in a pool it will be fine” chlorine is bad for your wetsuit. Look at all the people that use the same T-shirt in the pool and never wash it, it is a different color because of the chlorine. I have also just discovered something called Saltaway- this is great stuff to use to clean your suits and gear after a week or so of diving. I am not saying to use it if you have only used your suit for one dive, but you don’t need to use it every time you dive. It will help get all the salt off of your gear.

Improper Storage

As well as suffering heat damage, leaving your wetsuit wadded up in your gear bag, trunk, or garage will cause rapid deterioration, as it compromises the structure of neoprene. Hanging your wetsuit on a proper wetsuit hanger is the ideal storage, but if you’re limited on space, you can store it folded in half in a dry container once it is fully dry.

If you rinse your wetsuit with fresh water after every use, it should stay clean in most cases. However, you sometimes might find that your wetsuit gets a little funky. If you pee in it, it will get funky. Make sure that you always use a cleaner that is designed for wetsuits. The wrong type of cleaning product on your wetsuit can be the thing that damages neoprene. Some people say you have to get a new wetsuit every 3 to 5 years. The truth is it depends on how much you use it and how deep you go. Every time you dive deep it will compress the wetsuit and push some of the bubbles that are in the neoprene out. So there is no real time line on how long a suit will last. But like most things the better you treat it the longer it will last and more importantly the better it will treat you when you need it the most.

SCUBAPRO SUNDAY – Buoyancy

Buoyancy is key to a lot of things when diving. It helps make the dive easier in a lot of ways. When using a closed-circuit rig (CCR), it keeps you from rocketing to the surface, and it prevents you from dropping to the bottom when you stop to fix your gear or “Dräger” talk/ yelling at your dive buddy.

The keys to buoyancy are balance and breathing.

The two significant factors in achieving neutral buoyancy.

Wear the right amount of weight for the dive. This will differ depending on the thickness of your wetsuit/ drysuit and gear you are wearing, also water type fresh or salt.

Breathing slowly and evenly, so you do not have too much air in your breathing bag. If diving a CCR

Steps to help maintain buoyancy.

Pre-dive preparation.

Buoyancy control begins with pre-dive preparation as you pick what to wear for a dive. Double-check to make sure nothing has changed that could affect buoyancy. A new wetsuit is more buoyant than an older one and will need more weight. A new suit has more inherent buoyancy at first because diving, especially deep diving, bursts the tiny bubbles in the suit over time. Make sure you look at any new gear compared to the old version. Equipment is constantly evolving and updated with new buckles or martial, so when you switch from old to new, make sure you know the buoyancy with the new stuff. Check the weights on a scale; often, there is variation between claimed and actual weight. If diving open circuit, remember cylinders are negatively buoyant when full and less negative when empty.

Do a buoyancy check.

Here is the best way to do a proper buoyancy check. With your lungs half-full, you should float at eye level with no air in your BCD. If you are diving open circuit, remember the average cylinder loses about 5 pounds as it empties. So, you might have to add about 5 pounds to your weight if you have done your buoyancy check with a full tank.

Keep a log

Keep a log of what gear you have worn, the temperature, and the type of water (salt/fresh /brackish). What equipment you used, how much lead you carried, your body weight, and whether you seemed too heavy or light. Knowing the weight of the gear that you used on the dive will help. Make sure you understand that if you are going to remove something during the dive, you need to account for that on the return trip home. If you plan by recording in training what you used, it will help when you have to do it the next time.  

Saltwater VS Freshwater.

If most of your driving is done in the ocean, ballast calculations should be done for saltwater. Jumping in the pool to check your ballast will get you close, but it won’t be 100% correct. If you switch back and forth, you’ll need to adjust your ballast. Be prepared to add weight if needed sometimes, it’s nice to have a weight belt with extra pouches just in case, or maybe just an empty pouch on a gear belt will help. But still, try and keep the weight evenly distributed.

Buoyancy, Trim, Position, and Breathing

The secret to buoyancy control begins with fine-tuning your weighting. How much lead do you put into your pouches or have on your weight belt? If you carry just the right amount of weight, you will only have to put a little air in your BCD. That means less drag and more efficient finning. Less BC inflation also means minor buoyancy shift with depth, so you’ll have to make fewer adjustments. There are many tricks, but buoyancy control is a fundamental skill. Precise control of your buoyancy is what enables you to hover motionless and fin through the water at any depth. It would be best not to use your hands and not stir up mud or silt from the bottom by always moving your feet. In addition to using the right amount of weight, make sure you are correctly balanced to optimize your position underwater.

Keeping a more horizontal position makes you more hydrodynamic. Distribute the weight as uniformly as possible from side to side; you should never notice that you put more weight on one side while driving. It would help if you also considered the weight of your dive gear and any other additional gear you might be wearing. I.e., gun belt or special equipment. Make sure it is balanced on your body, and it doesn’t shift when you are diving. The lower you wear your dive rig can cause a tendency to push the diver forward (upside down) in the water, so the placement of weight towards the back can help reverse this position, especially on the surface. Make sure any dive weight you put on can be easily removed in an emergency.

Besides ballast weight, the factors that affect your buoyancy are BC inflation, your trim, exposure suit, depth, and breathing control. Your ballast weight and your trim are the only two factors that, once you’ve selected them, stay put. Ballast is the amount of weight it takes to keep you neutral in the water. Trim is about the position of your body weight relative to the position of your weight. Sometimes when diving a rebreather, you can tape lead washers on it to help with your trip.

There is one more thing to understand that will help with your buoyancy. It is controlling your breathing. Make sure you maintain proper breathing. Take relaxed breaths. This allows you to maintain control over your buoyancy.

To determine the amount of weight you need, you can take your body weight, the diving suit you will use, the weight of your equipment, and the environment you are diving in salt or freshwater. If you use about 10 percent of your body weight, that is a good starting point for a full 5 mm or more and for a 3 mm suit, use 5 percent of your body weight.

Drysuits and thick neoprene suits require more ballast to counteract the increased buoyancy of those suits compared to the thinnest. Body composition (the muscular density, for example) will also influence the necessary weight. Remember, fat floats, muscle sinks.

Remember to calculate everything you will use and wear on your dive if you are doing a long drive and plan to leave or remove something halfway thru your dive. Say conducting a ship attack, and you are taking limpets off. Plan for the whole dive, not just the start when you will be at your heaviest; plan if you are carrying something that you plan to leave behind, how will that affect your extraction. To check your buoyancy, get into the water deep enough to stay in an upright position without treading and releasing all air from the vest. Inhale, normally, the surface of the water must be at the level of your eyes. When you exhale, you should sink until the water covers your head and inhale again. You should emerge once again until the level of the eyes. Adjust your weight in small increments, about 1 pound at a time. You can use a weight with a snap link or just some weight with some 550 cord on it. Make sure you don’t just put all the weight you are adding to one side. Try and use this time to even yourself out and set your trim also. I have also seen people tap lead washers to the front of their rebreather to help even them out. The rule of thumb is never add more than 10Lbs. that can’t be released.

Once you get your ballast weight and trim dialed in, you will be ahead of about 75% of all divers toward perfect buoyancy control. Now you can fine-tune your BC inflation to compensate for the very predictable changes due to breathing down your tank and changing depth.

Lastly, there are advanced classes that you can take that focus on advanced skills like this. This may seem like a lot of work, but it will help make diving a lot better and make you more efficient at your job.

SCUBAPRO Sunday – Combined Operations Assault Pilotage Parties

Sunday, September 4th, 2022

As I am sure you can tell, I love history. I find it amazing that even today, you can read something about WW2 that you never knew about. There were so many specialty units that sometimes it was hard to say, “Oh, this group gets its roots from…” Combined Operations is one of those groups, and they had so many smaller Units / Parties (I think I might have liked being part of “Parties” more than a Team. So, it would be “I am a party guy” and not “I am a Team guy”) that we are just now finding out about that they might not have been the father of some groups today. Still, they might have been the mother or the ugly step-sister.

While serving in the Second World War, Nigel Clogstoun-Willmott established the Combined Operations Assault Pilotage Parties (COPP), which were responsible for covert beach reconnaissance. This proved to be critical in the success of the Allied seaborne invasion campaign. Amphibious force attacks on land and sea are among the most dangerous of all military operations. Apart from the fact that they necessitate the precise coordination of armed forces on the ground, air, and sea, they might also be subjected to various issues associated with landing on foreign enemy beaches.

Among these are tidal roughness, inadequate sand and shingle texture, steep beach gradients, and restricted beach exits, for example. Various enemy defenses, including mines, beach obstructions, pill boxes, and gun emplacements, can make natural disasters more dangerous and challenging to overcome. Nigel Clogstoun-Willmott, an accomplished navigator in the Royal Navy, was one of the few who truly understood the gravity of the risks involved. He recognized that amphibious troops must be carefully directed into coastal waters by men who had been deployed to the coast ahead of the fleet.

Furthermore, he recognized that the only way to resolve these issues truly was to conduct a thorough reconnaissance of the proposed beach landing sites, work that would require men skilled in navigation, hydrography (marine surveying), and engineering to land covertly on the beaches at night.

Of all special forces operations, beach reconnaissance was one of the most clandestine and risky. The men engaged were forced to conduct their operations right under the noses of the enemy, knowing that if they were arrested and interrogated, their intelligence might jeopardize the entire operation and their lives.

In 1910, Clogstoun-Willmott was born in the Indian city of Shimla. A senior engineer, his father worked on significant infrastructure projects throughout northern India, including the construction of roads and bridges.

He was transported to England for his education, attending Lambroke School and Marlborough College until he was eight. He joined the Royal Navy when he was 17 years old, specializing in navigation and quickly earning a reputation as a creative problem solver and unique thinker.

The fact that he was aware of the dangers of landing on enemy shores came to him early in life. Gallipoli was the first sizeable amphibious operation of modern times, and his uncle ‘Cloggy’ had been severely wounded during the battle in 1915.

As a Beach Master for the landings at Narvik in the far north of the country, Clogstoun-Willmott received first-hand knowledge of these perils during the unsuccessful Norwegian campaign of 1940.

He was charming, courteous, and good-natured, but he was also a military professional who took his duties seriously. He spent a long time reflecting on the lessons learned from this campaign and how amphibious operations should be conducted going forward. In 1941, Clogstoun-Willmott was stationed in the Mediterranean with ‘Layforce,’ a commando group that had been dispatched to the Middle East. With the challenge of attacking the Italian-controlled island of Rhodes, Layforce got his first chance to put his theories into action.

As a result of his collaboration with Captain Roger Courtney, a canoeist who had recently created the Special Boat Section, which was primarily intended for marine reconnaissance operations, he could complete this task. Courtney and Clogstoun-Willmott worked together to conduct the world’s first in-depth military beach reconnaissance mission.

A wide variety of equipment was available, from flimsy cold-water suits made of heavily greased long johns and jumpers to the newest infrared signaling technology and the humble chinagraph pencil for taking notes in dripping wet conditions.

The mission was a resounding triumph. Both soldiers were honored, with Clogstoun-Willmott getting the Distinguished Service Order and Clogstoun receiving the Distinguished Service Medal. However, the valuable information gathered as a result of this work was never put to good use.

As a result of the British being lured into a futile attempt to resist the German invasion of Greece, the mission was called off entirely. Clougstoun-Wilmott was again called upon to serve as a Beach Master, coordinating British forces’ evacuation. His narrow escape from capture came after he commandeered a Greek caique and sailed it to Egypt, where he was one of the last to leave. Not until August 1942, following the failure of a massive raid on the French port of Dieppe, was it realized how essential Clogstoun-theories like Willmott’s were.

Admiral Louis Mountbatten, Director of Combined Operations, approached him and requested him to assemble a team – dubbed ‘Party Inhuman’ – to assist with Operation Torch, the invasion of French North Africa. He agreed and formed the team. When this endeavor proved successful, it resulted in the formation of the COPP in early 1943. The first order of business for the COPP was to conduct reconnaissance in preparation for the upcoming invasion of Sicily. However, due to insufficient training and equipment, achievement came at a high price this time. Only four of the sixteen guys who were assigned to the mission returned.

Later, Clougtoun-Wilmot, who is by nature a martinet and a training fanatic, collaborated with Mountbatten to guarantee that the COPP had access to the resources it needed to prepare for the invasion. The COPP teams were re-energized and contributed significantly to the Allied landings in Italy after re-energizing. During the D-Day landings, the COPP faced its most difficult challenge. COPP troops were now armed with tiny submarines known as X-craft, as well as specialty landing boats and diving gear, in preparation for the invasion of France.

They carried out a thorough study of the potential beaches and returned samples for analysis to establish that big trucks would be able to pass through them without being damaged. On D-Day itself, COPP personnel were dispatched ahead of the massive invasion fleet to ensure that it arrived safely. This scientific approach to warfare played an essential role in preparing for what was considered the most complex military operation in history.

While D-Day was the apex of the COPP’s operations, the unit also saw significant action in the Far East and the Mediterranean during its tenure. In 1945, it made it easier for people to cross the Rhine into the heart of Germany. Following World War II, the mission of the COPP was absorbed into what is now known as the contemporary Special Boat Service (SBS). They were beneficial during the amphibious operations during the Falklands War in 1982 due to their knowledge and expertise.

Later in life, Clogstoun-Willmott worked for the Navy in several positions and the intelligence agency MI5. At age 81, he passed away in Cyprus in 1992, after continuing to live an active life as a sailor until a few years before his death.

The COPP’s work was so closely guarded that it was not made public until after the Second World War had concluded. In the eyes of the public, Clogstoun-Willmott and his troops of the COPP continue to be unsung heroes of the Special Forces.
