The Engine Room

Salt and Crossing

Chapter 12: The Engine Room

The engine room was below the car deck, accessed by the companionway on the port side, the companionway a steel stairway that descended seven steps to the watertight door, the door fitted with a brass handle that had been polished by thirty-four years of hands until the brass was not the color of brass but the color of use, the color that metal achieves when it has been gripped and turned and gripped again ten thousand times, the handle's surface worn to a smoothness that was softer than the original machining, softer because the hands that had gripped it were softer than the tool that had cut it, and the softness was the record of the gripping, the evidence that the door had been opened and closed and opened again by men who went below to do the work that the passengers did not see and did not think about and did not know was being done.

Tommy opened the door. He opened it at 5:45, thirty minutes before the first departure, the opening the first act of the engine room's daily sequence, the sequence that began in the dark and the cold of the below-decks space and that ended sixteen hours later in the dark and the heat of the same space, the dark-to-dark the engine room's day, the day measured not by sunlight — the engine room had no windows, no portholes, no access to natural light — but by sound, by the engines' state, by the silence of the cold start and the hum of the idle and the roar of the full ahead and the silence again of the shutdown, the silence that bookended the day's noise.

The engine room was cold in the morning. The block heaters ran overnight, maintaining the engines at a temperature that would allow the starting to succeed without the grinding reluctance that cold iron produces when asked to move, the reluctance of metal that has contracted in the cold and that resists the starter's demand with the passive resistance of a thing that does not want to be disturbed, and the block heaters defeated this resistance, kept the iron warm enough to accept the starting, kept the oil fluid enough to flow, kept the coolant liquid enough to circulate, the heaters the engine room's nightwatch, the mechanical sentries that stood guard while the human crew slept.

But the air was cold. The block heaters warmed the engines but did not warm the space, and the space was steel — steel walls, steel deck, steel overhead — and the steel conducted the night's cold into the room with the efficiency that steel brings to all thermal transfer, the cold moving through the steel the way the current moved through the channel, by the physics of differential, the warm air inside seeking equilibrium with the cold air outside, the equilibrium never achieved because the steel kept conducting and the cold kept arriving and the engine room's air temperature at 5:45 in October was forty-one degrees, which was cold enough to see your breath and cold enough to make the hands stiff and cold enough to make the work harder, the wrenches colder, the fittings tighter, the body's objection to the cold a physical fact that the work overrode because the work was the requirement and the requirement was not negotiable.

Tommy descended into the cold. He carried a flashlight — the engine room had lights, fluorescent fixtures mounted to the overhead, but the lights were on the electrical panel's circuit and the panel was at the far end of the room and the reaching of the panel required the crossing of the room in the dark, the crossing a miniature of the larger crossing, a transit from one state to another, from dark to light, from cold to warm, from silence to the sound that the lights' ballasts produced, the electrical hum that was the engine room's baseline, the sound beneath the sound, the frequency that everything else was built on.

He switched on the lights. The fluorescents flickered — the cold slowed the gas in the tubes, the gas reluctant, the gas needing a moment to achieve the ionization that produced the light — and then caught, and the light filled the room, the flat white light of fluorescent fixtures reflecting off the steel surfaces and the painted machinery and the oil-darkened deck plates, the light revealing the engine room in its morning state, the state of readiness, the state of waiting.

The twin Caterpillar 3412s sat on their mounts in the room's center, one to port and one to starboard, the engines positioned symmetrically the way the propellers they drove were positioned symmetrically, the symmetry the design's logic, the balance that a twin-engine vessel requires, the two engines producing equal thrust, equal torque, the equality the straight tracking's foundation, the foundation on which the captain's corrections were built, the captain adjusting the balanced thrust with the wheel and the throttles to steer and to dock and to navigate the channel's currents and the wind's push.

Each engine was twelve feet long and four feet wide and four feet tall, and each engine weighed 4,200 pounds dry, the weight a number that Tommy did not think about because the weight was not relevant to the maintenance, was not something the hands needed to know, the hands needing instead to know the torque specifications and the fluid levels and the belt tensions and the filter intervals, the knowledge that the maintenance demanded, the practical knowledge of the man who kept the engines running.

He began the morning checks. The checks were the liturgy — Harlan's word, spoken once, years ago, the word sticking because the word was right, the checks performed in the same order every morning with the same attention and the same reverence, the reverence not religious but professional, the reverence of a person who understands that the checks are not bureaucratic but are essential, are the things that stand between the crossing and the failure, between the passengers and the ocean, between the safe arrival and the catastrophe.

Oil first. The port engine's dipstick was on the starboard side of the engine, positioned there by the engineers at Caterpillar who had designed the 3412 for marine applications and who had placed the dipstick where a mechanic could reach it in the confined space of an engine room, and Tommy reached it, pulled it, wiped it on the rag he carried in his back pocket — the rag a permanent accessory, the rag's presence in the pocket as constant as the thermos's presence on the wheelhouse shelf — inserted it, pulled it again, read it. Full. The oil was full because Tommy had checked it the previous evening and the oil had been full then and the engines did not consume oil between shutdown and startup, did not leak, did not lose, the oil remaining where the oil was supposed to remain because the seals were sound, the gaskets were sound, the maintenance was sound.

He checked the starboard engine. Full. He checked the reduction gears — the gears that converted the engines' 1,800 RPM to the propellers' 340 RPM, the gears that lived in their own housings aft of the engines, the housings filled with gear oil, the gear oil heavier than the engine oil, thicker, the oil's viscosity matched to the gears' demands, the demands of metal teeth meshing at speed under load, the teeth requiring the oil's film between them the way the hull required the water's buoyancy beneath it, the film and the buoyancy both invisible, both essential, both the thing that prevented the contact that would destroy — metal on metal in the gears, steel on rock in the channel — and the prevention was the maintenance, was the checking, was the daily act of verification that the film was there, that the oil was there, that the level was correct.

Coolant next. The coolant system was closed — fresh water and antifreeze circulating through the engine's water jackets, absorbing the combustion's heat, carrying the heat to the heat exchangers where the heat was transferred to raw seawater pumped from the channel through the hull, the raw water absorbing the engine's heat and carrying it back to the channel, the heat discharged through the exhaust, the engine's waste heat returned to the water that the engine propelled the vessel through, the cycle a closed loop of thermal exchange, the engine heating the water that cooled the engine, the water serving both purposes, the water's dual role — propulsion medium and cooling medium — one of the symmetries that the Constance's design embodied.

Tommy checked the coolant level in both engines. Full. He checked the raw-water strainers — the basket filters that caught the debris that the channel's water carried, the eelgrass and the seaweed and the occasional plastic bag and the jellyfish in August, the strainers protecting the heat exchangers from the clogging that would reduce the cooling flow and raise the engine temperature and trigger the overheat alarm that Tommy had heard four times in six years, four times when the strainers had become clogged between checks and the clogging had reduced the flow enough to raise the temperature enough to sound the alarm, and each time Tommy had descended to the engine room and had cleaned the strainers and had restored the flow and the temperature had dropped and the alarm had silenced and the crossing had continued, the strainer-cleaning a three-minute task that preserved the crossing, three minutes of Tommy's hands in the strainer basket pulling eelgrass from the mesh, the eelgrass the channel's contribution to the maintenance, the channel testing the Constance's systems the way it tested the captain's knowledge, by presenting conditions, by offering complications, by requiring attention.

The bilge. Tommy checked the bilge — the lowest point of the hull's interior, the sump where any water that entered the hull collected, the water arriving through the shaft seals or the through-hulls or the condensation that the temperature differential between the engine room's air and the hull's steel produced, the condensation a thin film of moisture on the steel's inner surface, the moisture collecting and running and dripping and pooling in the bilge, and the bilge pump removed the water, the pump automatic, the float switch activating when the water reached a preset level, the pump running until the water was below the switch's reset level, and Tommy checked the bilge every morning because the bilge was the hull's truth-teller, the bilge's water level the indicator of the hull's integrity, a dry bilge meaning the hull was sound, a wet bilge meaning the hull was leaking, and the distinction between dry and wet was the distinction between the crossing continuing and the crossing not continuing, between the ferry running and the ferry not running, and the bilge this morning was dry, was the same dry it had been every morning for the six years of Tommy's tenure, the dryness the hull's daily report on its own condition, the report that said: I am sound, I am holding, the water is outside where the water belongs.

The shaft seals. The propeller shafts exited the hull through openings in the stern, the openings sealed by packing glands that compressed a woven material — flax impregnated with tallow, the oldest sealing technology in maritime engineering, the technology unchanged since the age of sail — around the rotating shaft, the compression preventing the water from entering along the shaft's surface, and the seals were adjusted by tightening the packing gland's nuts, the tightening compressing the flax, and the adjustment was a judgment, a feel, the nuts tightened enough to prevent leaking but not so tight that the friction heated the shaft and damaged the packing, and the judgment was in Tommy's hands, in the hands' calibration of tightness, the calibration learned from Harlan who had learned it from James who had learned it from William, the knowledge passed down through four generations of Goss hands, each generation's hands teaching the next generation's hands what tight-enough felt like, the feel untranslatable into torque specifications or foot-pounds, the feel a thing of the fingers, a thing of the skin's sensitivity to the resistance that the nuts offered when they were right, the rightness a sensation, a click that was not audible but tactile, the fingers' recognition that the tightening had reached the point where more would be too much and less would be too little.

The steering gear. Aft of the engines, in a compartment that was the engine room's annexation of the stern, the hydraulic steering system lived — the pump, the cylinders, the lines, the rudder stock — and Tommy checked the hydraulic fluid level and the lines for leaks and the cylinder rods for scoring, the checks a visual inspection, the eyes scanning the components for the evidence of failure, the evidence that would be a puddle of red hydraulic fluid or a scratch on the chrome-plated rod or a loose fitting weeping fluid at the joint, and the evidence was not there, was never there, the steering system maintaining itself with the reliability that hydraulics provide when the fluid is clean and the seals are sound and the system is maintained, and the system was maintained because Tommy maintained it, because the maintaining was the work.

Seven checks. Seven stations. The liturgy completed in twenty-two minutes — the same twenty-two minutes as the crossing, the coincidence unplanned but fitting, the engine room's morning preparation requiring the same duration as the crossing it prepared for, the preparation and the act equal in length, the equality a symmetry that pleased Tommy in the way that all symmetries pleased him, the symmetries of the Constance's design and operation, the port and starboard engines, the bow and stern lines, the departure and arrival, the flood and ebb, the symmetries that organized the crossing the way the crossing organized the day.

He climbed the companionway to the car deck. The watertight door closed behind him. The engine room was ready. The engines were ready. The crossing could begin because the preparation had been completed, the invisible preparation, the below-decks work that the passengers did not see.

The passengers. The passengers boarded at 6:12 and drove onto the car deck and parked and sat in their vehicles or climbed to the passenger cabin, and the passengers saw the car deck and the cabin and the wheelhouse if they climbed to look, and the passengers heard the horn at 6:15 and felt the engines engage and felt the Constance move, and the passengers experienced the crossing as a surface experience, a deck-level experience, the experience of the visible and the audible, and beneath the experience, beneath the deck, beneath the car deck's steel plates, the engines ran, the engines that Tommy had checked and that Tommy had prepared and that Tommy would monitor throughout the day, monitoring not by standing in the engine room — the noise made prolonged presence impractical, the noise at full ahead 108 decibels, the decibel level that required hearing protection and that produced, even with the protection, the particular fatigue of sustained noise, the fatigue that is not physical but neurological, the brain's exhaustion from processing the relentless input — but by monitoring the gauges in the wheelhouse, the oil pressure and the coolant temperature and the RPM and the exhaust temperature, the gauges the engine room's ambassadors in the wheelhouse, the numbers that spoke for the engines, that said: we are running, we are within parameters, the oil is flowing and the water is cooling and the fuel is burning and the combustion is controlled and the controlled violence is producing the thrust that is moving the vessel that is crossing the channel.

Tommy monitored the gauges the way Harlan monitored the water — with the continuous, background attention that is not vigilance but is awareness, not watching but knowing, the gauges' numbers absorbed peripherally, the way a musician absorbs the sound of the other instruments, not listening for them specifically but hearing them, detecting the anomaly in the ensemble's sound, the wrong note, the off pitch, and the detection was Tommy's skill, the skill of hearing the wrong number in the gauges' ensemble, the oil pressure that was five PSI lower than usual, the coolant temperature that was three degrees higher, the RPM that fluctuated by twenty when it should have been steady, and the hearing of the wrong number was the diagnosis's beginning, the beginning of the descent to the engine room, the descent to the source, the descent to the place where the problem lived and where the fix would be applied.

He had fixed many things. He had fixed the raw-water pump impeller on the port engine in August of 2021, the impeller's rubber vanes torn by a piece of shell that had passed through the strainer, the shell too small to catch but large enough to damage, and the damage had reduced the pump's flow and the reduced flow had raised the temperature and the raised temperature had spoken through the gauge and the gauge had spoken to Tommy and Tommy had descended and had found the impeller and had replaced it, the replacement a forty-five-minute job performed during the lunch break between crossings, the Constance at the dock, the engine room accessible, the spare impeller in the parts locker that Tommy maintained the way Harlan maintained the chart, with the care of a man who understands that the spare part is not a spare but is a future, is the next repair waiting to happen, the repair anticipated by the spare's presence, the anticipation a form of readiness, the readiness the ferry's state, the constant state.

He had fixed the alternator on the starboard engine in February of 2023, the alternator's bearing failed, the failure announced by a squeal that was audible through the deck plates, the squeal the bearing's cry, the bearing saying: I am dying, I am metal on metal, the oil film that should separate me has been breached and the breach is the beginning of the end, and Tommy had heard the squeal and had descended and had identified the alternator and had called the parts supplier in Rockland and had ordered the alternator and had installed it the following morning before the first departure, the installation requiring the removal of the serpentine belt and the disconnection of the electrical connections and the unbolting of the alternator from its bracket and the bolting of the new alternator and the reconnection and the re-tensioning of the belt, and the whole operation took an hour and fifteen minutes and was performed in the engine room's cold, in the February engine room where the breath was visible and the hands were stiff and the wrenches were cold and the bolts were reluctant and the work was hard, was the hard work of the invisible man in the invisible room performing the invisible repair that would allow the visible crossing to continue.

The invisible work. This was the engine room's condition, the engine room's defining characteristic — invisibility. The engine room was beneath the deck. The engine room was behind the watertight door. The engine room was where the passengers could not go and did not want to go and did not know existed in any meaningful sense, the passengers knowing that the ferry had engines in the way that they knew their cars had engines, abstractly, functionally, the engines a fact of the ferry's operation that did not require examination or understanding, the engines doing their job the way the heart does its job, without the body's conscious awareness, without the brain's active management, the engines' operation autonomous, automatic, and the autonomy was Tommy's gift, Tommy's contribution to the crossing — the autonomy was the product of the maintenance, the maintenance producing the reliability, the reliability producing the invisibility, the engines invisible because the engines worked, the working the evidence of the maintaining, the maintaining the work that Tommy did.

He was twenty-eight. He had been in the engine room for six years and he knew the engines the way Harlan knew the channel — by feel, by sound, by the accumulated experience of six years of checking and monitoring and fixing, the experience that had taught his ears the engines' normal sound and his hands the engines' normal vibration and his nose the engines' normal smell, the smell of diesel and oil and heat and the particular warm-metal smell that healthy engines produce, the smell of iron at operating temperature, the smell of combustion controlled, the smell of work being done.

He knew when the engines were happy. This was not anthropomorphism. This was the mechanic's language, the language that mechanics use because the language is accurate — happy engines run smoothly, maintain their temperatures, hold their pressures, produce their rated power without complaint, and unhappy engines do not, unhappy engines miss and stumble and overheat and lose pressure and produce less power and announce their unhappiness through the gauges and the sounds and the smells that the mechanic reads, and the reading is the diagnosis and the diagnosis is the beginning of the fix and the fix is the restoration of the happiness, the return to the smooth running that is the engine's natural state, the state that the engine was designed to maintain and that the mechanic's maintenance maintains.

The engines were happy today. The engines had been happy most days. The engines' happiness was the product of thirty-four years of maintenance — Harlan's maintenance and, before Harlan, the maintenance performed by the state's mechanics and the contract mechanics from Pendleton Marine and the traveling Caterpillar technicians who came to the island twice a year for the scheduled service, the service that replaced the filters and the belts and the fluids and the wear items that the operating hours consumed, and the scheduled service was the maintenance's framework, its architecture, and Tommy's daily checks were the maintenance's mortar, the small daily acts that filled the gaps between the scheduled services, the acts that caught the problems before the problems became failures and the failures became breakdowns and the breakdowns became cancellations and the cancellations became the crossing not happening.

The crossing not happening. This was the thing the engine room prevented. This was the engine room's purpose, its reason, its justification — the crossing happened because the engines ran and the engines ran because the maintenance was done and the maintenance was done because Tommy was there, below decks, in the noise and the heat and the oil and the dark, performing the invisible work.

The bridge would end the invisible work the way it would end the visible work. The bridge would end the engine room the way it would end the wheelhouse, the below-decks the way it ended the above-decks, the mechanic's work the way it ended the captain's work. The bridge required no engine room. The bridge required no daily checks, no oil levels, no coolant temperatures, no shaft seals, no bilge pumps, no raw-water strainers. The bridge required maintenance of its own — the cables and the deck and the expansion joints and the lighting and the drainage — but the bridge's maintenance was a different maintenance, was the maintenance of a static structure rather than a dynamic vessel, and the difference was the difference between keeping a thing in place and keeping a thing in motion, and the keeping-in-motion was the harder task, was the more demanding task, was the task that required Tommy's daily descent into the engine room's noise and heat and the performance of the liturgy and the monitoring of the gauges and the readiness to descend again when the gauges spoke their warning.

The bridge would not need Tommy. The bridge would not need a man who knew the engines by sound and by feel and by the six years of mornings that had taught his hands the shaft seals' tightness and his ears the alternator's bearing's health and his nose the difference between the normal warm-metal smell and the abnormal hot-metal smell that said something is wrong, something is failing, something needs attention. The bridge would stand on its pilings and span the channel and carry the traffic and the bridge would not care about Tommy's hands or Tommy's ears or Tommy's nose, because the bridge was not a vessel and did not require a crew, and the not-requiring was the obsolescence, was the word that described what the bridge did to Tommy and to Harlan and to the Constance and to the engine room and to the invisible work.

Tommy stood on the car deck. The engine room was below him. The engines hummed beneath his feet, the hum transmitted through the deck plates, the hum that was the engines' voice, the voice that said: we are running, we are sound, the crossing is possible because we are running and we are sound, and the possibility was Tommy's achievement, Tommy's daily contribution, the contribution that the passengers did not see and did not know about and that the bridge would render unnecessary, the contribution ending not because the contribution was insufficient but because the crossing was ending, and the ending of the crossing was the ending of everything the crossing contained — the captain and the deckhand and the wheelhouse and the engine room and the wheel and the gauges and the oil and the coolant and the liturgy and the invisible work and the visible work and the twenty-two minutes and the 1.4 miles and the constancy and the name.

Tommy put his hand on the deck. The deck was warm. The warmth was the engines' warmth, the heat rising through the steel the way the heat rose through the water in the heat exchangers, the thermal transfer connecting the engine room to the car deck, the below to the above, the invisible to the visible, the warmth the engines' handshake with the surface, the engines saying through the steel: we are here, we are below, we are doing the work, and the work is warm and the warm is the work and the work is the crossing and the crossing is now.
