Main-engine and auxiliary reliability sits at the centre of a vessel’s commercial performance. A machinery defect at a Sri Lankan port can put a laycan at risk, and the speed of a competent local response often decides whether a vessel sails on time, particularly for ships holding a tight schedule on a Colombo transhipment call. ARCSHIP provides planned and emergency engine overhauling and marine mechanical solutions alongside berths and at anchorage at Sri Lanka’s commercial ports.
Planned overhaul versus emergency repair
Planned overhauls are carried out against the vessel’s planned maintenance system and the engine maker’s running-hour schedule, piston and cylinder-unit overhauls, cylinder-head and valve work, bearing inspections, and pump and cooler servicing. Emergency repair responds to an unplanned defect: a scavenge fire, a bearing failure, a cooling-water leak or a fuel-system fault that must be rectified before the vessel can sail.
Main-engine work
Typical main-engine scope includes de-carbonising and overhaul of cylinder units, renewal of piston rings and liners, grinding and lapping of valves, examination of main and bottom-end bearings, and re-commissioning with performance checks after reassembly.
Auxiliary and machinery work
Auxiliary scope covers generator engines, purifiers, compressors, pumps, heat exchangers and coolers, and steering and deck machinery, supported by pressure testing, alignment and re-calibration where required.
The cost of a machinery defect is measured less in the repair itself than in the off-hire it causes if the response is slow.
Planning an overhaul at a Sri Lankan port
- Advise scope and running hours early so units, gaskets and spares can be pre-positioned.
- Confirm permits and access for hot work, enclosed-space entry and lifting in port.
- Align with the survey calendar so class attendance and machinery work happen together.
- Combine with calibration, an overhaul is the natural time to complete instrument and gauge calibration.
Why in-house engineering matters
Delivering overhaul, mechanical, calibration and safety work under one QHSE system, with a single point of accountability, shortens the critical path and avoids the interface risk of coordinating separate contractors. For owners trading through the Indian Ocean and calling in Sri Lanka, that means faster, more predictable machinery repair and less time off-hire.
