Inside of the lifetime of a deep sea saturation diver, just one of the most hazardous and isolated careers in the earth

• Chris Lemons was a saturation diver for 10 a long time operating on oil fields on the North Sea ground.

• Now, Lemons is a supervisor, who presents directions to divers and is dependable for holding them alive.

• In 2012, Lemons pretty much died on the sea ground in an incident, and was rescued over 30 minutes later on.

When he is not participating in golfing or spending time with his wife and two daughters, Chris Lemons is living in a tiny pressurized chamber at the bottom of a boat, hundreds of meters below the surface area of the sea.

He spends 28 times at a time in this article, functioning on an oil area on the floor of the North Sea. Lemons is a supervisor now, but formerly worked as a saturation diver, named immediately after the system of breathing pressurized air that saturates the blood and tissue of divers so their ranges are in line with the pressure of the sea ground.

“I was just pretty youthful, my extremely early twenties, and in fact, I failed to really know what to do with my lifestyle,” Lemons told Insider about discovering his way into his 18-yr diving career.

A friend’s father aided him out with a summer time task doing the job on the back again deck of a dive guidance vessel. There, he received to see a glimpse of the world he would shortly enter — a entire world he mentioned he failed to have any real notion of or even realized existed.

“They all seemed like enigmas a minor bit,” Lemons said about seeing saturation divers arise from their chamber. “They possibly turned up in fancier cars than me on the vital facet as perfectly, so that was an appeal. Pretty rapidly, I assumed that’s what I would appreciate to do.”

He continued operating on the boat and concluded teaching for air diving — the system made use of for diving in shallower h2o than deep sea web sites — in Scotland.

For eight a long time, Lemons was required to function as an air diver to acquire knowledge for saturation diving programs, which he eventually did in Marseille, France, right before shelling out 10 many years as a saturation diver.

He talked to Insider about what the job’s like, his occupation route, and his incident that impressed a documentary.

Life in the pressurized chamber

Lemons joked that the most significant talent for staying a saturation diver just isn’t diving, but being personable enough to reside in the pressurized chamber. There can be up to 11 other individuals in the chamber, and not anyone will get along all the time, he reported.

“I’ve normally identified it truly is a great leveler of persons since you get men and women coming in with egos and what ever and it isn’t going to final extremely long due to the fact you happen to be brutally uncovered everyday when you might be functioning,” he told Insider.

He ongoing: “It is fairly a monastic way of residing for the reason that you are in these chambers, so you really don’t have any obtain to liquor, you’re training each individual single working day since you’re doing the job in the water. You dwell really clear genuinely, and you breathe pure gas.”

The chamber is crammed with heliox, a combination of helium and oxygen. It is pressurized to the identical degree as the depth of the seabed the divers are functioning on. If they are doing the job at 100 meters, for instance, the chamber is pressurized to the exact same stage as 90 to 95 meters underneath sea degree.

The downside is a absence of sunlight, he explained. But residing in the chamber as well lengthy has its psychological impacts also, Lemons reported.

“I feel the day you start sensation that is a normal thing to do, a typical put to dwell or function, then it truly is most likely time to get out,” Lemons reported. “I undoubtedly felt which is what stopped me. I love the diving, but sooner or later you get exhausted of dwelling in people situations.”

Lemons claimed he can communicate to his family whilst residing in the chamber since he has access to internet and telephones, but his voice is influenced by the depth the divers live at and the helium in the chamber.

Immediately after expending 24 times in the vicinity of the bottom of the sea, coming straight again to the area is not an possibility, due to the fact a diver could die of decompression sickness, or as its a lot more typically recognised, “the bends.”

The deeper a diver goes, the far more nitrogen is absorbed into their tissue. If they ascend as well quickly, the gas bubbles in the diver’s overall body will broaden and can rupture the tissue or block arteries and stop the circulation of oxygen to the brain.

If Lemons goes to the depth of 100 meters and spends six hrs down there, the approach of decompression can take four days.

“You will find no circumnavigating that 4 times of decompression,” Lemons stated. “If you break your leg or your mother dies, it won’t make a variance, you nonetheless have to do 4 times of decompression.”

In the British isles, Lemons mentioned saturation divers are legally restricted to residing in the chambers for 28 times, so they may well expend 24 days performing on the seabed, then decompressing for 4 times.

Performing at 100 meters below the area of the sea

Lemons is effective in the North Sea which he explained likely has the highest safety standards in the earth for divers.

There are four teams of a few divers on his vessel who every include six several hours on the seabed. The boat runs 24 several hours a working day.

Divers are decreased towards the seafloor on a diving bell which requires about an hour to start and an hour to arrive back, indicating divers are in the water for about eight hrs a working day.

“It can be truly a program, you basically do the exact same point at the very same time, every one working day,” Lemons said.

When the divers wake up, they’re despatched a food stuff menu from which they can decide on what they want to take in. The meals is sent in on silver trays as a result of a fuel lock.

Afterward, the divers are supplied paperwork telling them what perform they are accomplishing for the working day, and are briefed by the dive supervisor on the mitigations and risks.

A single diver usually stays powering in the diving bell as a rescue diver, and to handle the a few “umbilical cords” that are connected to the divers in the drinking water, Lemons explained. A person wire is for gas to breathe, a single is for warmth, and 1 is for light.

Lemons operates completely in the oil and gas business, placing in and inspecting wells, pipelines, and the hydraulic and digital infrastructure that keeps the oil discipline likely.

“You can have days when it can be rather intricate work,” Lemons stated. “You usually have an engineer and a dive supervisor conversing to you by way of an earpiece, so you are fed info and techniques.”

Other times require the divers lumping sandbags all over the seabed for six hrs, he stated.

The incident

In 2012, Lemons was on the work when the dynamic positioning system, which retains the boat in location, failed.

Lemons’s umbilical cords snapped, and he was still left at the bottom of the sea with only 5 excess minutes of respiration gasoline. He was rescued immediately after above 30 minutes, for the duration of which he explained he was largely unconscious.

A documentary named “Previous Breath” was built in 2018 about Lemons’s incident. But he claims he feels disassociated from the incident when imagining about it or observing the film.

“I assume for all a few of us who ended up included in the h2o that working day, I will not experience any of us really feel we have experienced any sort of trauma,” Lemons reported. “It was a major function in our lives, absolutely, but in a strange way, it truly is been a positive factor for me.”

For the reason that he was continue to early in his vocation, Lemons explained he was far more concerned about losing the work soon after his incident than grappling with the gravity of pretty much getting rid of his lifetime.

Immediately after a three week investigation, Lemons explained he selected to return to his career, and the 3 associates of his diving workforce resumed do the job as normal.

“The folks who put up with are not seriously the a few of us who can have an impact on the result, it is the persons you go away at house — your relatives, your good friends, the ones who have to sit at residence and think about the worst.”

Now, Lemons publicly speaks about his career as a saturation diver, and talks about the incident to advertise safety and share what he realized from the encounter.
