Main Engine 2-Stroke · Main Engines (2-Stroke)
This maritime equipment falls under the category of large marine diesel engines. The APL Maritime model is the HYUNDAI-WARTSILA 10RTFLEX, designed for high-performance propulsion in ocean-going vessels. This engine belongs to the BAPMN1810MDE EPA engine family, with a displacement per cylinder of 1809.5 liters and a total displacement of 18095.6 liters. It is a two-stroke compression ignition engine with direct injection and a turbocharged fuel system, suitable for variable speed applications with fixed pitch propellers. The engine is certified under IMO Category 3 and operates at a rated power of 57200 kW at 102 rpm, delivering a torque of 3939 Nm. Common failures include cylinder-condition deterioration due to poor lubrication or wear, fuel-injection faults, scavenge-air restriction, exhaust-valve or exhaust-path faults, bearing distress, and starting-air or maneuvering-control issues. To maintain the engine, it is essential to carry spare parts such as fuel-injection components, cylinder-lubrication service parts, seals, gaskets, filters, and starting-air valve components. Regular maintenance checks should include monitoring cylinder exhaust temperatures, lubrication conditions, scavenge air quality, bearing temperatures, and conducting oil analysis and vibration checks. Additionally, inspecting scavenge spaces and accessible cylinder components for deposits and blow-by evidence is crucial. The manufacturer and class requirements should be followed for the exact inventory of spare parts.

What our service work and the manufacturer documentation say about keeping this model running.
Trend cylinder exhaust temperatures, cylinder lubrication, scavenge condition, bearing temperatures, lubricating-oil analysis and shaft or engine vibration. Inspect scavenge spaces and accessible cylinder components for deposits, blow-by evidence, liner condition, broken ring debris and signs of hot spots or scavenge fire. Check fuel-injection equipment, starting-air components, cooling-water circuits, lubricating-oil systems and exhaust components for leakage and correct operation. Review crankcase and bearing-monitoring records and inspect thrust-bearing and shafting interfaces where accessible. A surveyor should verify alarms, shutdowns, overspeed protection, turning-gear interlocks, starting-air safety arrangements and emergency controls applicable to the installation. For cylinder dimensions, rotational speed, pressures, clearances, temperatures, wear limits and setting values, refer to the manufacturer documentation for the exact figure.
Carry fuel-injection components appropriate to the engine, cylinder-lubrication service parts, seals and gaskets, filters, starting-air valve or control components and essential pump spares. For critical ocean-going propulsion, the onboard spare scale commonly also covers selected cylinder-head or exhaust-valve parts, piston-ring and liner-service items, bearing-related spares and key sensors or control components, subject to the actual engine design. Use the manufacturer and class spare requirements for the exact inventory.
