Marine Diesel Fitter

While engine room automation monitors cylinder exhaust temperatures, automated viscosity controllers manage fuel heating, and condition based vibration monitors track bearing wear, hands on shipboard engine fitting remains shielded from automation. Physically pulling thirty ton cylinder heads with overhead engine room gantry cranes in rolling sea swells, taking precision inside micrometer measurements of worn cylinder liners, feeling for bearing clearances with lead wire, and executing emergency open ocean engine repairs during generator blackouts demand raw mechanical stamina, tactile precision, and seasoned seafaring grit.

Operating across maritime corridors connecting the Port of Mombasa, the Port of Lamu, and global ocean trade routes, marine diesel fitters keep the world merchant fleet moving. Guided by the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers STCW under the Kenya Maritime Authority, these vital engine room craftsmen prevent catastrophic propulsion failures at sea, maintain environmental emissions compliance, and ensure uninterrupted maritime shipping.

A typical shift involves conducting engine room watch rounds, inspecting fuel purifier throughput, rigging the engine room gantry crane to pull a worn piston on unit three, measuring liner wear, and testing fuel injectors. Typical daily tasks encompass: Logging main engine cylinder exhaust temperatures, scavenging air pressures, and bearing oil temperatures during sea watch.; Stopping, cleaning, and reassembling the discs on a heavy fuel oil centrifugal purifier separator.; Rigging the motorized engine room gantry crane to unbolt and hoist a two ton cylinder cover and piston out of the engine block.. You coordinate closely with cross functional colleagues to align on immediate deliverables, double checking equipment readiness and standard operating protocols.

In the afternoon, you execute core deliverables, consult with cross functional colleagues, document operational outcomes, and ensure that all equipment and handover notes are fully updated before completing the shift. Before completing the shift, you reconcile physical logs, review operational checklists with the oncoming team, archive incident reports, and brief project supervisors on task completion.

Marine Diesel Engine Shipboard Fitters overhaul, maintain, rebuild, and troubleshoot massive two stroke low speed and four stroke medium speed marine diesel propulsion engines, auxiliary diesel generator sets, heavy fuel oil purifiers, and turbochargers aboard merchant ships, commercial tugboats, and naval vessels. Operating inside roaring, hot engine rooms deep in the hulls of ships, they overhaul giant pistons and cylinder liners, scrape and fit white metal crankshaft bearings, lap high pressure fuel injection valves, and balance crankcase running gear while keeping vessel machinery running during long open ocean voyages.

Core responsibilities include disassemble, overhaul, clean, and reassemble multi ton marine diesel engine cylinder heads, exhaust valves, and pistons., operational coordination, and ensuring strict adherence to Kenyan statutory frameworks and quality standards.

Key organizations hiring for this role include Kenya Ports Authority KPA Marine Operations, Kenya Maritime Authority KMA, Kenya Pipeline Company KPC Offshore Terminal, Kenya Coast Guard Service, alongside expanding opportunities in Nairobi, Mombasa, Kisumu, and regional infrastructure projects.
