The Cough Beneath Their Feet

Three days later the generator stumbled.

Lena was in the port corridor with a coil of line over one shoulder and a wrench in her back pocket when the hum under the floor changed.

Not stopped. Worse.

It caught.

A short hitch in the steel. A break in the vibration she felt through the soles of her boots before her ears named it. The Rig seemed to hold itself still around the missing sound. A woman ahead of her, carrying water tins, froze mid-step. Someone behind a hatch stopped talking.

Then the hum returned. Thin at first. Then fuller. The old steady pulse climbing back into place like a man getting to his feet after a blow.

Nobody moved for a second.

Then the woman with the water tins kept walking. Voices started again, quieter than before. Somewhere above, a hatch slammed.

Lena stood with the line biting into her shoulder and listened.

The generator ran. But not right. There was a rough edge in it now, almost lost under the normal rhythm, the mechanical equivalent of a breath taken too shallow.

She turned and went below.

The lower levels were warmer, close with diesel heat and the damp mineral smell of old concrete. As she came down the last stair the air changed again, sharper with fuel and hot metal. The generator room door stood open. Mikkel was inside, bent over the side housing with one hand braced on the casing. Brin stood opposite him, a gauge in one grease-black hand, her head angled toward the machine as if listening through it.

Neither looked up when Lena entered.

“What happened.”

Brin answered first. “Injector lag.”

Her voice was flat, all of it pointed at the problem. “Fuel feed stuttered on cylinder three. Pressure dropped, then caught.”

“Cause?”

Brin set the gauge down on the housing. “Assembly’s degrading faster than we thought.”

Mikkel wiped a hand over his mouth. “Could be fouling.”

Brin shook her head once. Certain. “Not fouling.”

She reached past him and tapped the injector mount with two fingers. “Seal’s not holding clean. It’s letting air in on the draw.”

Lena stepped closer. The machine’s heat found her face. She looked where Brin pointed. The seam was dark with fresh residue. Not much. Enough.

“How long.”

Brin wiped her hands on a rag already ruined. “Could be a week. Could be tonight.”

Mikkel made a small sound in his throat. Not disagreement. Weariness.

“The new part?” Lena asked.

“Need one,” Brin said. “Or something close enough I can strip and machine down.”

“From where.”

“There was a marine diesel workshop north of Peterhead before the water came up. If it’s still there. If it hasn’t been stripped clean.”

Lena nodded once. She knew the ifs. They all did.

Brin bent to the toolbox on the floor and came up with a chalk nub. She crossed to the bulkhead and, on a patch of old paint already ghosted with previous numbers, drew a quick cutaway of the assembly. Fuel line. Mount. Seal. Intake. Her hands moved fast. No wasted marks.

“This is where it’s failing,” she said. “We can keep coaxing it for a while, but every time it coughs, it scores the chamber more. Then it’s not a seal problem.”

“Then what.”

“Then it’s the whole assembly.”

Mikkel gave Lena a look from across the machine. Tired eyes, steady enough. He was letting the girl speak because the girl knew. The room had already shifted around that fact.

Lena asked, “You sure on the part.”

Brin’s mouth flattened. “Yes.”

It came out sharper than the rest. Not rude. Just exhausted from having to be right before anyone would believe it.

Lena looked at the chalk sketch, then at the real machine, then back at Brin. Sweat had darkened the hair at her temples. There was a smear of black across one cheekbone she hadn’t noticed. Her hands were moving again already, sorting tools, arranging bolts by size in a line on the floor.

The line on the floor shivered once.

Lena realized it was Brin’s fingers, not the steel.

“Have you eaten,” she said.

Brin looked up then, as if the question had arrived in the wrong room. “What?”

“Have you.”

A beat.

“Not since morning.”

Mikkel said, without turning, “Told her to go.”

Brin ignored him.

Lena crouched by the open toolbox and picked up the failed seal between thumb and forefinger. Rubber gone hard. Edge furred with salt. Dead, mostly.

“We make a list,” she said. “Exact dimensions. Exact housing type. Any alternates that’ll fit.”

Brin nodded at once. “I have them.”

“Written.”

“In my bunk.”

“Bring them to me.”

Brin hesitated, just enough to say she didn’t like being told. Then she set down the wrench in her hand. “Fine.”

She started for the door, wiping one palm against her trousers again. Frustration. Fatigue. Something held too tight under both.

Lena’s hand rose before she thought about it.

Toward the girl’s shoulder. Six inches, maybe less.

Brin turned at the movement.

Lena stopped. Dropped her hand. “Eat first.”

Brin looked at her for one unreadable second. Then she nodded and went out.

The room felt different after she left. Larger, somehow, and worse for it.

Mikkel was tightening a fitting by touch more than sight. Lena watched the wrench in his hand travel a little too far, then correct.

“She’s right,” he said.

“I know.”

Mikkel worked the wrench back free. “Didn’t say you didn’t.”

The generator gave a low uneven shudder under his palm. Not failure. A warning.

Lena set the dead seal on the housing and looked at the old mechanic. “How bad.”

He let out a breath through his nose. “Bad enough I stopped sleeping through the night.”

That was answer enough.

By evening the whole Rig knew something was wrong.

Not because anyone said it plain. Because the generator’s cough had gone through their feet and into their bones, and on the Rig people learned to hear danger in things that technically still worked. Water was distributed in quieter lines. The mess hall carried more listening than talk. Even Petra, chalk on her fingers, sat by the wall and drew without scraping the stick too hard.

Lena found Brin in the same corridor after dark, coming up from the lower deck with a folded sheet of paper in one hand and a lamp battery in the other.

“The measurements,” Brin said.

Lena took the paper. The figures were neat, dense, exact. Notes in the margins. Two alternate housings. Three possible seal materials. A cross-section sketch better than the chalk one.

“You wrote this before today.”

Brin shifted the battery to her other hand. “I knew it was going.”

“How long.”

Brin looked past Lena at the closed hatch behind her. “A while.”

Not an answer. The only one Lena was going to get.

She unfolded the page fully under the corridor light. “Workshop north of Peterhead. You sure.”

“I’m sure.”

“Been there?”

“No. Saw a parts catalog once. Same supplier markings as the old marine units on the Norway settlement.” She paused. “If the flood didn’t take the upper stock.”

Lena folded the page again. Tucked it into her jacket pocket.

Brin said, “If you go, you’ll need to check the injector chamber sizing before you pull. There were two models that year. They look the same until you strip the casing.”

Lena nodded. “Write the difference.”

“I can just come.”

The words landed between them without warning.

Lena looked at her.

Brin’s face had gone still in the way it did when she was braced for someone to tell her no. “I know the part. I know what to look for. You don’t.”

“I know enough.”

“Enough takes longer.”

“It’ll take what it takes.”

Brin’s fingers tightened around the battery. “You’ll waste half a day searching blind if the shelves are mixed.”

“You’re needed here.”

The answer came too fast. Lena heard it, heard what sat under it, and knew Brin had heard it too.

Brin said nothing for a moment. The corridor hummed around them with distant pipe-noise, the low throb of the machine below. Then she nodded once. Small. Shut.

“Fine,” she said.

She moved past Lena, close enough that the cold air she brought up from below touched Lena’s sleeve. She did not look back.

Lena stood there with the folded measurements in her pocket and listened to Brin’s steps go down the corridor. Quick, light, controlled. Then a hatch opened. Closed.

Only after the sound was gone did Lena realize she had shifted half a pace after her without meaning to.

She stayed where she was.

Later, in her bunk, with the lights out and the Rig making its night noises in the walls, she took the paper back out and read it again by torchlight.

Exact dimensions. Exact tolerances. A note at the bottom in smaller writing: if none of these fit, check the fuel injector assembly itself for wear along the inner seat. If scored, don’t reinstall. It’ll fail under load.

The handwriting was tight and clean. No wasted space. The kind of notes written by someone who expected to have to rely on paper because relying on people had never paid well.

Lena folded it carefully and slid it under her pillow.

She lay back without sleeping.

The generator ran beneath the floor and through the frame of the bunk, carrying its roughened pulse into her spine. Not steady enough. Still there.

A week, Brin had said. Maybe less.

Lena stared into the dark.

Below decks, somewhere distant and familiar, the machine kept turning. Above decks, the ocean pressed its long weight against the legs of the Rig. Between those two pressures forty-seven people slept, or tried to.

Lena listened until the sounds sorted themselves into what would kill them now and what would wait until morning.

The generator’s new rhythm did neither. It sat between. A warning carried through steel.

She closed her eyes.

In the dark behind them, for one brief uninvited second, she saw chalk on painted metal. Brin’s hand moving fast. The confidence of the lines. The way she had looked up when Lena asked if she’d eaten, as if the question belonged to another life.

Lena opened her eyes again.

By morning she had already chosen the route north.
