Chapter 3: The Bell Run

The bell run began in the trunk.

The trunk was the passage between the living chamber and the transfer chamber — a cylindrical steel tube, ninety centimetres in diameter, perhaps two metres long, connecting one pressurised world to another. You crawled through it on your hands and knees, dragging your equipment bag behind you, the steel cold against your kneecaps, the walls close enough to touch with your elbows, the hatch at the far end a circle of fluorescent light that was identical to the light behind you but that led, through the transfer chamber and one more hatch, to the bell.

Kwame went through the trunk at 05:30. Mac was already in the transfer chamber, pulling on his hot water suit — the KRUG suit, named for the Norwegian company that made them, a two-piece garment of neoprene with a network of small-bore tubes sewn into the fabric through which hot water circulated continuously during the dive, the water heated on the vessel and pumped down through the umbilical to the diver at depth, the only thing standing between a man and the hypothermia that would set in within minutes in the three-degree water of the North Sea at 150 metres.

Without the hot water suit, you would be dead in twenty minutes. This was not hyperbole. This was thermoregulation. At 150 metres, the helium-oxygen breathing mix conducted heat away from the body seventeen times faster than air, and the water temperature was 3.2 degrees Celsius, and the combination of these two facts meant that an unheated diver would lose core temperature at a rate that would render him unconscious in fifteen minutes and dead in twenty-five, and no amount of neoprene or willpower could prevent it.

So the hot water flowed. It entered the suit at the chest, distributed through the tube network to the arms, the legs, the back, the feet, and it kept the diver's skin at approximately thirty-two degrees, which was not warm by any standard but was warm enough, was the minimum temperature at which the body could function and the hands could grip tools and the brain could make the decisions that diving at 150 metres required.

Kwame pulled on his suit. The neoprene was stiff from the previous rotation — suits were assigned to individual divers and stored in the chamber between uses — and it smelled of the particular mixture of sweat and seawater and rubber that was the smell of saturation diving, a smell that did not wash out and that Kwame associated not with discomfort but with work, with the specific state of readiness that preceded a bell run, the body armoured in neoprene and hot water tubes and the knowledge of what came next.

Fraser was ready. Fraser was always ready before anyone else, a function of his personality — tightly wound, efficient, anxious in a productive way — and his physical build, which was compact, everything close to the centre, no wasted space. He was thirty-four, from Inverurie, a town north of Aberdeen, and he had been diving for nine years and in saturation for six, and he had the particular competence of a man who had survived the learning curve and settled into the plateau of reliable performance that the industry valued above brilliance.

Three men in the bell. That was the standard configuration: two divers and one bellman. Two would lock out and descend to the work site; the third would remain in the bell, monitoring communications, managing the umbilicals, ready to assist if something went wrong. Today, Kwame and Mac would dive. Fraser would tend the bell.

The bell was spherical, two metres in internal diameter, painted orange inside and out — the international colour of "find this if it sinks" — and it was accessed from the transfer chamber through a bottom hatch that opened downward into the bell's interior. The hatch was the interface between the chamber system and the bell, and when it opened, the pressures had to be equalised: the transfer chamber and the bell at the same 15.2 bar, so that when the hatch swung down there was no rush of gas, no pressure differential, just a smooth transition from one enclosed space to another, the way a hallway connects two rooms.

Kwame lowered himself through the hatch. The bell's interior was arranged with the economy of a space that had been designed, redesigned, and designed again to fit three men and their equipment into a sphere the size of a large wardrobe. Two benches, one on each side, padded with closed-cell foam. Between the benches, the gas panel — the manifold of valves that controlled the breathing gas supply to each diver's umbilical and the emergency bailout bottles. Above, the communications panel, the lights, the camera that transmitted video to the surface. Below, between the divers' feet, the bottom hatch that opened onto the sea.

The bottom hatch. The place where the bell became a diving bell — not a chamber, not a vessel, but a bell, the mouth open to the water, the air trapped inside by nothing more than pressure, the divers stepping through the opening and into the ocean the way a man steps through a doorway, except that the doorway was at the bottom of a steel sphere suspended 150 metres below the surface of the North Sea, and on the other side of the doorway was water so cold and dark that the word "ocean" did not adequately describe it. Ocean implied vastness, horizon, the possibility of distance. At 150 metres, there was no horizon. There was only the reach of your helmet light — perhaps two metres in the North Sea murk — and beyond that, darkness so complete that it was not the absence of light but a substance, a medium, a thing you moved through the way you moved through water itself, by displacing it.

Mac came through the hatch. Then Fraser. The bell was full.

Fraser sealed the upper hatch, checking the seal, checking the locking dogs, checking the pressure equalisation valve. He was methodical. He was always methodical. In the bell, methodical was not a personality trait but a survival strategy.

The communications crackled. Sarah Webb's voice, from the dive control room two decks above: Bell team one, comms check.

Mac keyed the microphone. Bell team one, loud and clear. Ready for launch.

A pause. Then Gary Hendricks: Bell team one, you are cleared for launch. Target depth one-five-zero metres. Bottom time six hours. Work scope: pipeline survey at KP 47.3, preparation for spool piece cut-out. Good luck, lads.

The bell lifted. Kwame felt it in his stomach — the familiar lurch as the handling system raised the bell from its clamp on the transfer chamber and positioned it over the moon pool, the square opening in the vessel's hull through which the bell would descend into the sea. The movement was hydraulic, smooth, the bell swinging gently on its lifting wire, the three men inside feeling the motion through their bodies the way passengers feel a train leaving the station, the subtle acceleration that meant the journey had begun.

Then the descent.

The bell dropped through the moon pool and into the water, and the world changed. The sound changed — from the mechanical hum of the vessel to the aquatic hum of the ocean, a low, pervasive frequency that was not sound exactly but pressure, the weight of the water pressing against the hull, the vibration of the lifting wire, the chatter of the umbilical bundle paying out from the vessel above. The light changed — from the fluorescent brightness of the chamber system to the green-grey glow of the moon pool's underwater lights, then rapidly to darkness as the bell descended past the vessel's hull and into open water.

Kwame watched through the viewport. He always watched, even though there was nothing to see. The viewport was a small circle of reinforced glass, ten centimetres in diameter, and through it he could see the water transitioning from grey to green to dark green to black as the bell sank, the light from the surface attenuating with depth according to the exponential function that governed all light in water — halving every ten metres in the North Sea, so that at fifty metres there was less than one per cent of the surface light, and at 150 metres there was nothing, or rather there was the theoretical possibility of light, the mathematical residue of photons that had been scattered and absorbed by 150 metres of cold, particulate-laden seawater until what remained was not light but the memory of light.

The descent took twelve minutes. Twelve minutes from the moon pool to the sea floor, the bell sinking at a rate controlled by the winch operator topside, the rate calibrated to allow the divers to equalise, to adjust, to watch the depth gauge count upward — fifty metres, seventy, ninety, one hundred, one-twenty, one-forty — each number a further commitment, a further distance from the surface, a further immersion in the physics of depth.

In the bell, the pressure did not change. The bell was already at 15.2 bar, the same pressure as the chamber, the same pressure as the water at 150 metres. The men inside breathed the same heliox, heard the same helium voices, felt the same density of atmosphere. The bell was an extension of the chamber, a mobile fragment of the habitat, a bubble of survivable conditions carried down through the water column to the work site.

But the feeling changed. Kwame had tried to describe this to people who had never dived — to the woman at the pub in Aberdeen who had asked him what his job was, to Yaw on the phone, to his mother in a letter he had drafted and never sent — and had never found the words that matched the experience. In the chamber, the pressure was abstract. You knew it was there. You saw it on the gauge. But the chamber was static — it sat on the vessel, connected to the world above, and the pressure was a number, a condition, a fact.

In the bell, the pressure became real.

You could feel it. Not physically — physically, the pressure inside the bell was identical to the pressure in the chamber — but spatially, psychologically, in the knowledge that the steel sphere you were sitting in was descending through water that would kill you in seconds if the sphere failed, that the only thing between your breathing lungs and 150 metres of black ocean was the integrity of this ball of welded steel plate and the competence of the engineers who had designed it and the inspectors who had tested it and the handling crew who had maintained it and the winch operator who was lowering it and the Life Support Technician who was monitoring the atmosphere inside it.

The bell was the between.

Not the chamber, which was the habitat. Not the sea floor, which was the work site. The bell was the space between — the transition, the passage, the vessel that carried you from one state to another. In the bell, you were neither in the world nor in the water. You were in the bell. You were in the between.

Kwame had thought about this often enough that the thought had worn a groove in his thinking, a channel through which his mind moved when the bell descended, the way water moves through an established course. The between was not a comfortable place. It was not designed to be comfortable. It was designed to be survived — to keep three men alive for the twelve minutes of descent and the six hours of bottom time and the twelve minutes of ascent, and then to be survived again the next day, and the day after that, for twenty-six days, the bell descending and ascending twice a day, carrying its cargo of men to the bottom and back, the world's most expensive elevator in the world's most hostile shaft.

But the between was where Kwame lived. Not just in the bell — in his life. Between Ghana and Scotland, between Accra and Aberdeen, between the son his mother had raised and the diver the North Sea had made, between the person who sent money and the person who should have been present, between the letters he received and the letters he did not write, between the voice his mother would recognise and the helium voice he actually spoke with for twenty-eight days at a stretch.

He had lived in the between for eighteen years. The bell was simply the most literal version of it.

One hundred and fifty metres. The bell settled. The descent stopped, the lifting wire going slack for a moment before the winch operator took up the strain and held the bell at depth, hovering three metres above the sea floor, the bottom hatch positioned above the work site.

Fraser opened the bottom hatch. The sea did not come in. This was the fact that never stopped being extraordinary, no matter how many times Kwame witnessed it: the bottom of the bell was open, a circular hatch one metre in diameter, and below it was the North Sea at 150 metres, and the water did not rise into the bell because the pressure inside the bell matched the pressure outside, and the air — the heliox — was lighter than water, and so the gas stayed in the bell and the water stayed below it, the interface between the two held in place by physics alone, a meniscus of pressure at the mouth of the bell, the oldest engineering principle in diving, the trapped air pocket, the inverted cup.

Kwame could see the water. It was black. Flat. The surface of it trembled slightly with the bell's movement, and in the light from the bell's external lamps it looked like oil — viscous, heavy, absorbing the light rather than reflecting it. Below the surface of the water in the bottom of the bell was the ocean, and below that, three metres down, was the sea floor: grey clay, scattered with shells and stones and the occasional brittle star, the sediment stirred into a slow haze by the current.

He could see the pipeline. It ran across the sea floor from left to right, a steel tube thirty inches in diameter, coated in concrete weight coating to keep it stable on the seabed, the concrete cracked in places to reveal the yellow anticorrosion coating beneath. This was the pipeline they were here to repair — a gas export line connecting a subsea wellhead to a platform forty kilometres to the east. The buckle was at KP 47.3 — kilometre point 47.3, measured from the pipeline's origin — and the stress corrosion cracking in the weld heat-affected zone had been identified by an inspection pig six months ago and classified as requiring immediate repair, which in the offshore industry meant "within six months," which was how long it had taken to schedule the vessel and the divers and the materials and the weather window and the permits and the procedures that would allow six men to be sealed in a chamber and lowered in a bell to the bottom of the North Sea to cut out a section of damaged pipe and weld in a new one.

Kwame fitted his diving helmet. The Kirby Morgan SuperLite 37 — a fibreglass shell with an acrylic viewport, a demand regulator that delivered heliox at ambient pressure, a communications system, and a light. The helmet sealed to the neck dam of his hot water suit, creating a closed system: the diver inside, the ocean outside, the breathing gas flowing through the umbilical from the bell's gas panel, the hot water flowing through the suit's tubes from the bell's hot water supply, the communications flowing through the umbilical's comm wire to the surface, the video flowing from the helmet camera through the umbilical's video cable to the monitors in the dive control room.

The umbilical was the lifeline. A bundled cable, approximately fifty metres long, containing the breathing gas hose, the hot water hose, the communications wire, the video cable, and the pneumofathometer — a small-bore tube open at the diver's end, through which the surface could measure the diver's exact depth by reading the back-pressure. The umbilical connected the diver to the bell, and the bell's own umbilical connected the bell to the vessel, and together they formed a chain of supply and communication that extended from the dive control room on the vessel to the diver on the sea floor, a vertical thread of survival stitched through 150 metres of water.

Kwame checked his bailout bottle — a small cylinder of breathing gas, strapped to his harness, containing enough heliox for approximately ten minutes of breathing at depth. The bailout was for emergencies: if the umbilical was severed, if the gas supply failed, if the bell lost pressure, the bailout bottle was the diver's last resource, the final margin between survival and not, ten minutes of breathing in which to reach the bell and reconnect or, if the bell was not reachable, to die slowly in the dark as the gas ran out.

He did not think about this. He thought about it constantly. Both of these statements were true.

Mac was ready. They checked each other's equipment — a ritual as formalised as any religious observance, each man inspecting the other's helmet seal, umbilical connections, bailout bottle, harness, hot water supply, communications. Each check was a small act of trust: I am looking at the things that will keep you alive, and I am confirming that they are correctly configured, and I am telling you this with my hands and my eyes and my voice, and you are trusting me because you have no choice, because at 150 metres there is no one else.

Kwame sat on the edge of the bottom hatch. His fins were on. His helmet was sealed. The hot water was flowing — he could feel it circulating through the suit, warm against his chest and arms and legs, the sensation of being held by warmth in a world of cold. His breathing was steady — the heliox flowing through the demand regulator with each inhalation, the exhaled gas bubbling away through the exhaust valve, each breath a small negotiation with the atmosphere.

He looked down. Black water. The pipeline below, illuminated by the bell's external lamps. The work site.

He dropped.

The entry was a controlled fall — feet first, arms at his sides, the umbilical paying out behind him, the water closing over his helmet with a sound that was not a splash but a compression, a sudden enclosure, the world contracting to the volume of his helmet and the reach of his light. The cold hit immediately — not through the suit, which was heated, but through the exposed skin of his face behind the viewport, a sharpness that the body registered as information: you are in cold water. You are at depth. You are working.

He descended three metres to the sea floor. His boots touched the clay. He was standing on the bottom of the North Sea at 150 metres, his helmet light illuminating a circle of seabed perhaps two metres in diameter, beyond which there was nothing — not darkness, because darkness implies the possibility of light, but nothing, the absolute absence of the visual, the world reduced to the small pool of illumination that moved with him as he moved.

Mac dropped beside him. They stood on the sea floor together, two men in hot water suits and diving helmets, connected to the bell above them by umbilicals that curved up through the water in slow arcs, their lights crossing and separating as they turned their heads, the beams picking out the particles suspended in the water — the marine snow, the constant slow rain of organic matter falling from the surface to the deep, the detritus of the living ocean drifting down through the water column like ash.

The pipeline was three metres to the east. They walked toward it — not walked, exactly, but moved with the slow, deliberate gait of men carrying the weight of their equipment and the resistance of the water and the knowledge that each step had to be placed carefully because the seabed was uneven and the visibility was poor and a fall at depth was not like a fall on the surface. A fall at depth tangled your umbilical and strained your connections and put you face-down in the clay, and getting up again in a diving helmet and a hot water suit and fins was an exercise in controlled frustration that used time and energy and gas, none of which you had in excess.

They reached the pipeline. Kwame knelt beside it and ran his gloved hand along the concrete weight coating, feeling for the buckle, the deformation that the inspection pig had identified. The concrete was rough under his gloves, colonised by marine growth — hydroids, barnacles, a thin film of algae that made the surface slippery. The pipeline was alive, in the way that all subsea structures become alive — the ocean claiming every surface, colonising every material, converting man-made infrastructure into artificial reef, the boundary between the built and the natural dissolving over time the way the boundary between the diver and the ocean dissolved over time, the suit and the helmet and the umbilical becoming, over the course of a career, extensions of the body rather than protections for it.

He found the buckle. A lateral displacement of perhaps fifteen centimetres — the pipeline had moved sideways at this point, pushed by a combination of thermal expansion and seabed movement, and the stress had concentrated in the weld heat-affected zone, the narrow band of metal adjacent to a weld where the welding process had altered the steel's microstructure, making it susceptible to cracking.

He could see the crack. With his light close to the surface, the crack was visible as a dark line in the weld cap — not dramatic, not the gaping fracture that a layperson might imagine, but a tight, fine line that ran along the toe of the weld for perhaps 200 millimetres. Two hundred millimetres of crack in a pipeline that ran for 120 kilometres. A fraction. An insignificance, measured by length.

But cracks grew. Cracks in pipelines under pressure always grew. The internal gas pressure pushed against the pipe wall, and the crack opened fractionally with each pressure cycle, and the crack tip advanced through the steel the way a root advances through soil — slowly, relentlessly, the force of the growth so small that it could only be measured with instruments but the cumulative effect so certain that it could be predicted with mathematics. Left alone, this crack would grow until it penetrated the pipe wall, and the gas inside would find the opening, and the pipeline would leak, and the leak would erode the crack edges, and the crack would grow faster, and the pipeline would fail, and the gas would escape into the ocean, and the failure would cost millions to repair and would, depending on the severity, potentially endanger the platform it served.

Kwame's job was to prevent this.

He reported to the surface. Kwame to dive control. At KP 47.3. Visual inspection confirms lateral buckle, approximately one-five-zero millimetres displacement. Crack visible in the weld heat-affected zone, approximately two-zero-zero millimetres length. Consistent with the pig inspection report. Ready to begin preparation for cut-out.

Sarah Webb's voice came back, processed through the unscrambler: Confirmed, Kwame. Topside copies. Proceed with cut-out preparation. Mark the cut lines at five hundred millimetres either side of the defect.

He marked the cut lines with a wax crayon, the traditional method — a wax mark on the concrete coating, visible through the murk, durable, simple. Five hundred millimetres either side of the crack, giving a spool piece length of one metre plus the two hundred millimetres of the crack itself. The new spool piece — a pre-fabricated section of pipe, delivered to the sea floor by crane — would be welded into the gap, the joints made by Kwame's hands in the light of his welding arc at 150 metres, the metal joining metal in conditions that would have been unimaginable to the men who invented welding and that were, to Kwame, simply the conditions in which he worked.

Mac was surveying the seabed around the pipeline, checking for debris, for obstructions, for anything that might complicate the cut-out or the installation of the new spool piece. He moved slowly through the murk, his light swinging, his voice coming through the communications system in the helium register that had become, over five years of partnership, as familiar to Kwame as his own.

Seabed's clear, Mac said. Good clay bottom. No debris. We can set up the alignment clamps anywhere along here.

Kwame acknowledged. He continued his survey of the damaged section, photographing the crack with the helmet camera, measuring the buckle displacement with a ruler held against the pipe, recording the data that the engineering team topside would use to finalise the repair procedure. This was the unglamorous work of saturation diving — not the welding, which was the skill, but the preparation, which was the discipline. Hours of survey and measurement and reporting before a single cut was made, because at 150 metres you could not afford to discover a problem after you had committed to a procedure. Every variable had to be identified, assessed, and planned for while the pipe was still intact, because once the cutting began the clock started, and the clock ran against you, and the sea floor was not a workshop where you could stop and think and consult a manual. The sea floor was a place where the current pushed and the cold crept and the darkness pressed and the umbilical tugged and the bell waited above you with its open bottom hatch and its ten minutes of bailout gas and its promise of return that was conditional on everything going right.

They worked for five hours. Five hours on the sea floor, in the dark, in the cold that the hot water suit held at bay but never eliminated, the cold always there at the edges — the face, the hands when the gloves shifted, the feet when the hot water distribution lagged. Five hours of survey and measurement and marking and reporting, the work proceeding with the deliberate pace that saturation diving demanded, each task checked and confirmed and recorded, the video feed running constantly, the surface watching through Kwame's helmet camera what Kwame saw through his viewport.

At the end of the shift, they returned to the bell. Mac went first, hauling himself up through the bottom hatch with the practised movement of a man who had entered and exited a diving bell three thousand times. Kwame followed, his umbilical reeling in as he ascended, the bell's interior small and bright and warm after the sea floor's vast darkness.

Fraser had maintained the bell throughout the dive — monitoring the gas pressures, managing the communications, keeping the bell's internal atmosphere within parameters. He helped Kwame and Mac remove their helmets and stow their equipment, and the three of them sat in the bell's small space, their hot water suits steaming faintly in the bell's warmer air, their breathing slowing, the adrenaline — or whatever the helium-saturated equivalent of adrenaline was — receding.

The ascent took twelve minutes. Twelve minutes from the sea floor to the moon pool, the bell rising through the water column, the darkness becoming less dark and then grey and then the green glow of the moon pool lights and then the mechanical sounds of the vessel and then the clamps engaging and the bell locked into the handling frame and the mating flange connecting the bell to the transfer chamber and the hatches opening and the trunk passable and the living chamber waiting.

They crawled back through the trunk. The chamber was warm and bright and smelled of food — someone had heated curry, the spice cutting through the processed air, the smell so ordinary and so welcome after five hours at the bottom of the North Sea that Kwame felt it as a physical sensation, a small decompression of the spirit.

Mac sat on his bunk. He looked at Kwame and said, Good start.

Kwame nodded. It was a good start. The pipeline was as expected, the damage was as reported, the conditions were workable. Tomorrow they would begin the cutting. In three or four days, the spool piece would be in place and Kwame would weld, and the welding was the part he was good at, the part that justified his presence at 150 metres, the skill that the industry paid for and that he had refined over eleven thousand hours of practice into something that was not artistry — he would not use that word — but precision, the ability to lay a bead of molten metal in conditions where the pressure and the cold and the darkness conspired against the integrity of every weld, and to produce, consistently, joints that met the code, that passed the inspection, that would hold for twenty-five years in the North Sea's corrosive, pressured, unforgiving environment.

He ate the curry. It tasted like cardboard with spice. He did not mind. He drank tea from a plastic mug. He sat at the fold-down table and wrote in his notebook: First bell run. Pipeline at KP 47.3. Crack as expected. Mac in good form. Temperature on the bottom 3.2 degrees. The current was light — maybe half a knot. The visibility was poor — maybe two metres. The usual.

He wrote: Mama's letters will be starting to accumulate. The first one might have arrived today. Or yesterday. The postman delivers at 11. The letterbox is stiff — I keep meaning to oil it. She would have written on Sunday, posted on Monday. Airmail from Accra to Aberdeen takes 5-7 days. The letter will be on the floor below the letterbox, lying on the other letters, the bills and the junk mail. Blue aerogramme. Her handwriting. My name in her hand.

He closed the notebook. He put it under his pillow. He lay in his bunk and listened to the chamber — the ventilation, the scrubbers, the distant sound of the vessel's engines, the occasional voice from the intercom, Sarah Webb reading out the atmospheric parameters in her calm, precise voice, the numbers that meant they were alive.

Fifteen point two bar. Zero point four PPO2. Zero point three per cent CO2. Twenty-nine degrees.

The numbers held. The chamber held. The men slept. And above them, on the surface of the North Sea, the waves moved with the indifference of a system that did not know or care that 150 metres below, six men were breathing gas that had been mixed and compressed and delivered to them through steel pipes and rubber hoses and valves and regulators, the entire apparatus of survival humming quietly in the night, keeping them alive in a place where life was not natural, where life was an engineering project, where every breath was a collaboration between the man who breathed and the woman who maintained the system that made breathing possible.

Kwame dreamed of Accra. The market at Makola, the stalls dense with produce, his mother's voice calling prices, the sunlight falling on the yams and the peppers and the dried fish, the air thick with the smell of charcoal and palm oil and the particular dust of Accra that was red and fine and settled on everything — on the fruit, on the fabric, on his mother's hands, on the kitchen table where she wrote her letters, the dust of home coating the paper she sent to Aberdeen, so that when Kwame opened the aerogrammes he could sometimes see it, a faint red residue on the blue paper, the dust of Accra having travelled four thousand miles inside a letter to land on a table in a flat in Aberdeen where it mixed with the grey dust of Scotland and became something neither Ghanaian nor Scottish but between, a compound of two places that existed only in the letters and in the flat and in the accumulated distance of a son who had left and not returned.

He woke to the intercom. Sarah's voice. 05:00. Bell team two, prepare for bell run.

Not his shift. Bell team two was Tomasz, Sean, and Davy. They would dive today while Kwame and Mac and Fraser rested, the two teams alternating, twelve hours on, twelve hours off, the rotation that would carry them through twenty-six days of work at the bottom of the North Sea.

Kwame lay in his bunk and listened to the others preparing — the sounds of the hot water suits, the equipment checks, the crawl through the trunk, the hatch sealing, the bell launching. Then silence, or the chamber's version of silence. Mac was snoring. Fraser was reading. The television was off. The pressure gauge read 15.2 bar.

He reached under his pillow and opened his notebook. He wrote nothing. He held the pen above the page and thought about the letter he should write to his mother, the letter he had been meaning to write for three weeks, the letter that would say the things he could not say on the phone and did not say in person because he was never in person, was always at distance, was always in the between.

Dear Mama, he would begin, because that was how he began every letter he wrote to her, which was not many, which was not enough.

Dear Mama.

The pen hovered. The page waited. The chamber hummed around him, holding its pressure, holding its atmosphere, holding its six men in their steel tube in the North Sea, and somewhere above, above the vessel and the waves and the sky, there was a world where letters were written and posted and received, where a mother's handwriting crossed the distance between continents, where words on blue paper carried the weight of everything that could not be said aloud, and Kwame held his pen above the page and did not write, and the not-writing was its own kind of pressure, a compression of the things unsaid, building in the chamber of his chest the way the helium had built in the chamber of steel, slowly, invisibly, to a depth from which the return would be long.
