Chapter 4: The Chamber

The chamber was three metres in diameter. A man standing with his arms outstretched could touch both walls. A man lying in his bunk could press his feet against one curve of steel and his head against the shelf that served as a headboard and feel, with both extremities, the limits of the space that was his home. Twelve metres long, three metres wide, the living chamber of the saturation system held a volume of approximately eighty-five cubic metres, of which perhaps sixty were habitable once you subtracted the bunks, the table, the equipment lockers, the medical lock housing, the toilet and shower enclosure, the television mount, the gas supply manifold, and the bodies of six men.

Ten cubic metres per man. The volume of a large wardrobe. That was the space each diver occupied for twenty-eight days.

The chamber had its routines, and the routines were the architecture of sanity. Kwame had learned this on his first rotation, twelve years ago, when the confinement had pressed against him in a way that the pressure did not — the physical pressure being a matter of physics, manageable, calculable, while the psychological pressure of six men in a steel tube was a matter of personality and habit and the slow accumulation of small irritations that, in a normal environment, would dissipate but that in the chamber had nowhere to go, the irritations building like CO2 in an unscubbed atmosphere, invisible but toxic.

The routines were these:

Wake at 05:00 for the day shift, 17:00 for the night shift. The intercom chimed — Sarah Webb's voice, or the voice of the night-shift LST, a man named Colin whose voice was deeper and who read the atmospheric parameters with a slight hesitation before each number, as though confirming with himself that the number was correct before offering it to the men whose lives depended on it. The wake-up call included the chamber conditions: pressure, oxygen, CO2, temperature, humidity. These numbers were the first information of the day, preceding any other knowledge — the weather, the work scope, the news from the surface — because these numbers described the basic conditions of survival, and survival preceded everything.

Breakfast through the medical lock. The medical lock was a small cylinder, perhaps forty centimetres in diameter and sixty centimetres long, set into the chamber wall with a hatch on each side — one opening into the chamber, one opening onto the vessel's main deck. Items could be passed in and out through the lock by pressurising and depressurising the small cylinder to match the chamber pressure or the surface pressure, as needed. Food came in. Laundry went out. Medical supplies came in. Urine samples went out. Letters could come in, if anyone sent them. Notebooks could go out, if anyone wrote in them.

The food arrived in insulated containers, pre-portioned, labelled with each man's name and the meal — ASANTE, BREAKFAST — in the neat block capitals of the vessel's cook, a man named Terry who had worked offshore for twenty years and who understood that for the divers in saturation, the food was not merely nutrition but event, the only external input that varied from day to day, the only sensory change in an environment where the light was constant, the sound was constant, the temperature was constant, and the pressure was, by definition, constant.

Terry made an effort. He varied the breakfasts — porridge one day, eggs the next, bacon rolls, pancakes, fruit. He packed the containers carefully, added condiments, occasionally included a note — Fresh strawberries from the market, lads, enjoy — written on a slip of paper that was itself a small object from the outside world, a physical token of the surface, handled by hands that were at one atmosphere, that had touched the open air, that carried the invisible residue of the world above.

Kwame ate his breakfast sitting on the bench beside the fold-down table, his knees almost touching Mac's knees across the narrow surface. The table was barely large enough for four men to eat simultaneously, so they ate in shifts of two or three, the rotation managed by an unspoken agreement that allocated the table to the men who were about to dive first, on the theory that a man about to descend to 150 metres deserved the small dignity of eating at a table rather than balanced on the edge of his bunk.

After breakfast, the pre-dive checks. The hot water suits, the umbilicals, the helmets, the bailout bottles, the tools. Each item inspected, each connection tested, each valve operated and confirmed. The checks took forty-five minutes and were performed with the attention of men who understood that the equipment they were inspecting was the equipment that would keep them alive for the next six hours.

Then the bell run. The crawl through the trunk, the transfer chamber, the bell. The descent, the lock-out, the work, the lock-in, the ascent. Six hours at the bottom of the North Sea, then the return to the chamber, the removal of equipment, the shower — lukewarm, inadequate, the helium atmosphere making the water feel cooler than it was — and the meal, and the off-shift hours, and sleep.

This was the cycle. This was the rhythm. Day after day, for twenty-six working days, with the decompression to follow.

But between the cycles were the hours of coexistence, and these were the hours that tested the divers in ways the ocean did not. The ocean was an adversary you could respect — it applied its pressure evenly, without malice, according to laws that were understood and could be planned for. The chamber was different. The chamber was six personalities in a space designed for equipment, and personalities did not follow laws.

Mac was the easiest man in the chamber. He had achieved, over thirty years of offshore work, a state of equanimity that Kwame envied and could not replicate. Mac read his novels — he had brought four this rotation, all thrillers, all featuring men with guns in unlikely situations — and he watched the films on the television with the uncritical attention of a man who required only that images move on a screen, and he ate whatever was put in front of him without complaint, and he slept on command, his body switching off the way a machine switches off, the snoring beginning within minutes of his head touching the pillow.

Mac did not discuss his personal life in the chamber. He did not discuss it outside the chamber either, as far as Kwame knew, but the chamber amplified the absence — six men living together for twenty-eight days, and Mac's contribution to the personal was limited to the facts that could be inferred from observation: he was divorced, or had never married; he had no children, or had children he did not mention; he lived alone in Peterhead, a fishing town north of Aberdeen, in a house he had bought with dive money; he drove a Land Rover that was older than Davy; he drank Bell's whisky when he was onshore, and in the chamber he drank tea, cup after cup, the tea passed through the medical lock in vacuum flasks and consumed with a methodical regularity that suggested the tea was not a preference but a practice, a small ritual of normalcy in an environment where normalcy was a memory.

Fraser was less easy. Fraser talked. Not excessively — he was not Sean — but steadily, a continuous narration of his observations, his opinions, his plans for shore leave, his thoughts on the work scope, the food, the temperature, the television's film selection, the quality of the tea. Fraser's talking was not conversation — it did not require response — but commentary, a running description of his experience that served, Kwame suspected, as a method of self-regulation, the words forming a barrier between Fraser and the silence of the chamber, the silence that could, if you let it, become a pressure of its own.

Tomasz was quiet. He had been doing saturation work for eight years, which in the North Sea meant he had experienced every combination of personality and confinement that the industry could produce, and he had developed the particular patience of a man who had learned that twenty-eight days would pass whether you were comfortable or not, and that comfort was a function not of the environment but of the attitude you brought to it. Tomasz did crossword puzzles, in Polish, from books his wife sent from Gdansk. He completed one crossword per day, working in pencil, erasing rarely, the puzzles a private discipline, a daily exercise in precision that mirrored the precision of his diving.

Sean talked. Sean talked the way the ventilation system hummed — constantly, involuntarily, as a basic condition of his existence. In normal air, Sean's talk was tolerable, even entertaining, because his voice was warm and his stories were well-constructed and his timing was good. In helium, Sean's talk was something else. The helium voice — high, squeaking, the Cork accent made alien by the frequency shift — transformed Sean's anecdotes into a stream of sound that was half intelligible and half hallucinatory, the words recognisable but the delivery so distorted that Kwame sometimes felt he was listening to a radio tuned slightly off-station, the signal there but warped, the meaning arriving in fragments.

Sean knew this. He talked anyway. Talking was how Sean survived the chamber, and survival took the form it needed to take.

Davy was nervous. Not about the diving — Davy was a competent diver, careful, thorough, the kind of young diver who would, if he stayed in the industry, become excellent — but about the chamber. About the confinement. About the twenty-eight days. This was his sixth rotation, and Kwame could see that the newness had worn off but the adjustment had not yet been made, the transition from enduring the chamber to inhabiting it, from counting the days to living them. Davy counted the days. He had a small calendar in his bunk, and each night before he slept he crossed off the date, the X a small mark of progress, a record of survival, and Kwame recognised the gesture because he had done the same thing on his own early rotations, before he had learned that crossing off days was a way of wishing your life away, and that the days in the chamber were still days, still hours in which he breathed and thought and ate and existed, and that wishing them gone was wishing away the only time he had.

He did not say this to Davy. You did not say things like this to young divers. You let them find their own accommodation with the chamber, their own rhythm, their own way of making the steel habitable.

The off-shift hours were the longest. Twelve hours between bell runs, of which perhaps two were taken up by meals and pre-dive preparation and post-dive recovery, leaving ten hours of time that had to be filled. Ten hours in a steel tube with five other men, the television the only window onto the world, the books the only escape, the sleep the only privacy.

Kwame read. He had brought two novels this rotation: a Chinua Achebe — Arrow of God, which he had read before, years ago, in Accra, and which he was rereading now with the particular attention of a man who had left the continent the novel described and who found in its sentences the texture of a place he carried but could not touch — and a novel by a Scottish writer whose name he would forget by the end of the rotation, a crime thriller set in Glasgow that Mac had recommended and that Kwame read without engagement, the plot moving past him like the current at depth, present but not touching.

He read Achebe slowly. He read the sentences about Ezeulu and the village of Umuaro and the conflict between the old authority and the new, and he felt the words working on him the way pressure worked on the body — not as impact but as saturation, the meaning dissolving into his thinking the way helium dissolved into his blood, slowly, thoroughly, reaching into every tissue.

The world is like a Mask dancing. If you want to see it well you do not stand in one place.

He had stood in one place for six years. Aberdeen. The flat on Crown Street. The vessel. The chamber. The bell. The sea floor. These were the places he moved between, and together they constituted a single place, a single stance, a fixed position from which he watched the world dance and did not dance himself.

He wrote in his notebook. He wrote about the dive — the technical details, the pipeline condition, the crack geometry, the seabed topography. He wrote about the chamber — the temperature, the food, Sean's talking, Mac's reading, Davy's calendar. He did not write about his mother. He had not written about his mother in the notebook since rotation 38, when he had written three pages about her letters and then read what he had written and found that the words were inadequate, that no arrangement of English sentences could describe the particular quality of receiving a letter from a person who was simultaneously the most important person in your life and the most distant, a person whose handwriting you knew better than your own but whose face you had not seen in years except in photographs that were themselves a form of distance, a representation that reminded you of the real but was not the real, the way the unscrambler produced a voice that was almost your voice but was not your voice, was a processed approximation, close enough to communicate but not close enough to comfort.

The days passed. The chamber held its pressure. The bell descended and ascended. The pipeline repair progressed — the concrete coating removed, the pipe cleaned, the cut lines confirmed, the clamps positioned. Kwame worked and ate and slept and read and did not write the letter to his mother and did not call his brother and did not think about the blue aerogrammes accumulating on the floor of his flat in Aberdeen, except when he thought about them, which was constantly, the way the pressure in the chamber was constant — not noticed, not forgotten, simply there, the background condition of his existence.

On the fourth night, Mac said something unexpected. They were lying in their bunks, the lights dimmed, the chamber in its night-time mode — the ventilation quieter, the temperature dropped to twenty-seven degrees, the atmosphere holding that particular quality of enforced stillness that was not peace but was the closest the chamber came to it.

Mac said: I phoned my sister today.

Kwame waited. Mac did not volunteer personal information. This was new territory, unexplored, and Kwame approached it the way he approached an unfamiliar section of seabed — cautiously, with his light on, watching for hazards.

Mac said: She's selling the house. Our mum's house. In Peterhead. Mum's been dead four years now, and the house has been sitting empty, and Linda wants to sell. She says it's time.

Kwame said nothing. In the chamber, silence was a form of listening, and listening was a form of respect, and respect was the currency that kept six men sane in eighty-five cubic metres of steel.

Mac said: I havnae been in that house since the funeral. Four years. I drive past it sometimes, when I'm home. But I don't go in. Don't know why. It's just — the house is the house, you know? It's where she was. And if I go in and she's not there, then she's not there. And if I don't go in, she's still there, in my head. She's still in the kitchen making tea. She's still in the garden with the washing. She's still there.

Mac's helium voice made the words sound incongruous — the sentiment deep, the register high — and Kwame heard in the dissonance something that he recognised, the gap between what was felt and how it was expressed, the pressure of emotion being channelled through a medium that distorted it.

That's not how it works, Kwame said. He said it before he meant to, the words arriving at his mouth before his judgment could intercept them.

Mac said: How does it work, then?

Kwame said: You don't go in and she's not there. You go in and she's everywhere. Every room. Every surface. The marks on the walls. The smell. The shape of the space she made by living in it. You go in and she's so present it's worse than her being gone, because she's there but she's not there, and the house knows the difference even if you pretend you don't.

A silence. The chamber hummed. Somewhere, the scrubbers cycled.

Mac said: Aye. Maybe.

Kwame lay in his bunk and stared at the underside of Fraser's mattress above him and thought about what he had said and why he had said it and whether it was true and whether it mattered that it was true when he had not entered the house in Osu for six years and was therefore speaking from a theoretical knowledge of absence rather than a practical one, the way a textbook describes a weld procedure that the author has never performed.

But he knew. He knew the way you know the temperature of the water before you enter it — not by measurement but by the behaviour of the surface, the way the light sits on it, the way the current moves. He knew that the house in Osu was full of his mother's presence, and that her presence would be both a comfort and a confrontation, and that the confrontation was the reason he had not returned — not the cost of the flight, not the difficulty of scheduling, not the work, but the knowledge that walking into that house would require him to face the gap between the son he was and the son she deserved, the gap that widened with each rotation, each absence, each blue aerogramme he read and did not answer.

He did not say any of this to Mac. He had said enough. More than enough, probably. The chamber was a place where you learned the weight of words — each one taking up space, each one consuming the limited atmosphere of intimacy that six men could sustain, each one a pressure on the group dynamics that had to be managed as carefully as the oxygen partial pressure.

The night passed. Kwame slept in fragments — twenty minutes, thirty, an hour — the sleep of a man whose body was saturated with helium at fifteen atmospheres and whose circadian rhythm was governed by fluorescent lights and an intercom and the pressure gauge on the wall that never changed, that read 15.2 bar whether it was day or night, whether he was sleeping or waking, whether the surface above them was dark with storm or bright with the simmer dim, the gauge a fixed point in a world where everything else — the work, the weather, the letters, the mother, the distance — moved and changed and accumulated while he remained at depth, at pressure, in the chamber, in the between.

On day five, Kwame began the welding.

The spool piece had been lowered to the sea floor by the vessel's crane — a pre-fabricated section of pipe, one metre long, the same diameter and wall thickness as the pipeline, coated in corrosion protection but not yet in concrete, the concrete weight coating to be applied later by a separate vessel. The spool piece was Kwame's responsibility. He would weld it into the gap left by the cut-out of the damaged section, and his welds would be inspected by radiography and ultrasonic testing, and if the welds passed — and they would pass, because Kwame's welds always passed, because eleven thousand hours of practice at depth had given him a consistency that was not talent but discipline, the discipline of a man who understood that his welds were the difference between a pipeline that held and a pipeline that failed — the repair would be complete, and the pipeline would return to service, and the gas would flow, and the industry would turn.

But that was the next chapter. That was the work.

For now, Kwame sat in the chamber and ate his lunch — fish and chips, the fish tasting of cardboard, the chips tasting of cardboard, the entire meal a cardboard approximation of food that he consumed with the mechanical efficiency of a man who had long ago stopped expecting the chamber to provide pleasure and had settled, instead, for function.

He opened Achebe. He read. The words were better than the food. The words had flavour. The words had the taste of red earth and palm wine and the kind of authority that came from a writer who had stood in the place he described and had seen it well because he had not stood in one place but had moved through the world, had looked at it from multiple positions, had understood that the Mask was dancing and that to see it you had to dance too.

Kwame was not dancing. Kwame was sitting in a steel tube at fifteen atmospheres, reading about a world he had left, eating fish that tasted like the container it had arrived in, listening to the ventilation system recycle the air he had breathed and would breathe again, the same molecules of helium passing through his lungs and back into the chamber and through the scrubbers and back into his lungs, a closed circuit, a sealed system, the air going nowhere, the man going nowhere, the letters accumulating, the distance holding.

Sean was telling a story about a dive in the Gulf of Mexico. Tomasz was doing his crossword. Davy was watching a film — an action film, the sound turned low, explosions reduced to whispers by the volume control and further distorted by the helium atmosphere, so that the gunfire sounded like popcorn popping and the dialogue was unintelligible. Fraser was sleeping, his breath the steady rhythm of a man who had learned to sleep anywhere, in any atmosphere, at any pressure, the body's final adaptation to the chamber being the ability to surrender consciousness on demand.

Mac was reading his Tom Clancy. He had advanced perhaps fifty pages since the blow-down. At this rate, Kwame calculated, Mac would finish the novel approximately never.

The afternoon passed. The evening came, or what the schedule designated as evening — the lights unchanged, the pressure unchanged, the only evidence of time's passage being the clock on the wall and the meals through the medical lock and the rotation of the dive teams. Dinner was curry again. Kwame ate it. It tasted like the curry it was and the cardboard the helium made it. He brushed his teeth with the toothbrush he kept in a plastic bag hung from his bunk frame. He used the toilet behind the curtain that provided no acoustic privacy, the sounds of his body joining the catalogue of sounds the chamber held — the ventilation, the scrubbers, the sleeping, the talking, the eating, the breathing, the living.

He lay in his bunk. He opened his notebook. He wrote: Day 5. First weld tomorrow. Spool piece on the bottom, alignment clamps ready. The joint is a standard single-V butt, 7018 rods, low hydrogen. I have made this joint a thousand times. I will make it again tomorrow at 150 metres, in 3-degree water, in the dark, with two metres of visibility and a current that wants to push me off the pipe and a suit full of hot water that is not quite hot enough and a helmet full of helium that makes me sound like someone I am not.

He wrote: Mac's mother's house is being sold. Four years since she died and he hasn't been inside. I said something to him about it — about how the house holds the person, how the person is present in the space even after they are gone. I don't know why I said it. I don't know if it was helpful. I know it was true.

He wrote: I have not been inside the house in Osu for six years. Mama is still alive. She is still there. She is writing letters at the kitchen table in the house I grew up in, and the letters travel four thousand miles to a flat I have lived in for twelve years, and I read them in batches when I surface, and each batch is a record of the weeks I was not there, the weeks she spent writing to a son who was sealed in steel at the bottom of the sea, breathing gas that made his voice unrecognisable, doing work that she has never seen and cannot imagine, living a life that she knows only through the money he sends and the occasional phone calls he makes and the letters he does not write.

He closed the notebook. He put it under his pillow. He closed his eyes. The pressure held. The chamber held. The night, such as it was, passed over the vessel and the sea and the men in the steel, and Kwame Asante, saturation diver, welder, son, lay in his bunk at fifteen atmospheres and breathed the gas that the system provided and did not sleep and did not wake and existed, for a time, in the state between the two that the chamber made possible, the state of being present in the body and absent from the world, the state of being alive and unreachable, the state that his mother would recognise, if she could see him, as the state she wrote to — not a person but a condition, not a son but a distance, not Kwame but the space where Kwame should have been.
