Dive platoon at work
The dive platoon is at work underwater. “It’s a piece of cake on land”, says de Bruin, “but underwater it’s rather difficult because you have to do everything by feeling your way around.”
No detail is left to chance
No detail is left to chance, wetsuits must be water-tight and this includes the gloves.
Clear effects of nitrogen narcosis
In this diver’s eyes clear effects of the so called Martini Law are visible, for every ten metres you dive, it feels like you’ve knocked back an entire glass of martini.also known as nitrogen narcosis
Diving bell go’s down

After a dive the men perform a fast striptease
After a dive the men perform the quickest striptease. Their colleagues on deck help them take off the diving equipment within three minutes and rush them to the decompression chamber.

Diver in SSE (service supply equipment)
Diver in SSE (service supply equipment) outfit, this equipment is the most convenient if he needs to work in strong current conditions and is also safer, since it provides a constant air supply.
The diving bell is sent to a maximum depth of 50 metres
The diving bell is sent to a maximum depth of 50 metres with two divers in it.
Two divers ready to go deep
Two divers ready to go deep for the nitrogen narcosis test. Once they reach the 50 metre depth they receive instructions from the ship above and have to perform a number of exercises. They spend between 30 and 60 minutes in the diving bell.
Diver jumps overboard
Diver jumps overboard, his task underwater will be that of checking his two buddies inside the diving bell (bathysphere).
Dive Platoon on patrol
Once the mission is over, all signaling buoys and anchors are weighed, there is no need to keep the area clear of other vessels now.
Murky water, this is the typical environment where military divers are trained, visibility is very scarce and most of the tasks are carried out by ‘touch’.
Structure for training
The module to complete the underwater structure is lowered into the water, the piece is left to sink until the bottom, then it will be carried by two divers to its exact position and joined with the other modules.
Marching in extreme condition
Part of the physical training involves marching in extreme conditions in full gear, this proves particularly tough because the diver must carry several kilograms of equipment and he can feel his body temperature rise to 38 degrees Celsius or more.
Pair of divers ascends
Time for another shift, as one pair of divers ascends, the next two descend to continue the work on the bottom.
Trained to dive in any condition
The underwater soldiers are trained to dive, with or without air supply equipment, in any condition and practically anywhere.
Divers kill time in the ç
Diver in SSE outfit
Diver in SSE outfit, the equipment is checked three times before he jumps overboard. A small defect in the system could cause serious consequences during the dive.

Pushed by their fellow soldiers into the decompression chamber
After performing the fastest striptease, divers are literally pushed by their fellow soldiers into the decompression chamber, where they will remain until the nitrogen levels in their blood are back to normal.
Rush into the decompression chamber
Only minutes after ascending from a dive, divers have to rush into the decompression chamber, every second is valuable in order not to put the diver’s safety at risk.
Extra air supply for the first 15 minutes.
