Executive Marine Engine Survey Summary

Based on my investigation, visual inspection, operational testing, cooling-system pressure testing, and sea trial, my opinion is that the overall machinery condition is:

OVERALL MACHINERY RATING

GOOD — WITH DEEP-DIVE MAINTENANCE AND CORRECTIVE REPAIRS RECOMMENDED

Both MAN D2848LE401 engines demonstrated favorable starting characteristics, stable coolant temperatures, strong oil pressure, satisfactory turbocharger response, and smooth operation during the sea trial.

Both Twin Disc MG-5114A marine gears operated smoothly in forward and reverse, without abnormal clunking or excessive vibration.

The most significant deficiencies involve leaking seawater pumps, deteriorated cooling hoses and clamps, crimped fuel, oil and transmission lines, worn belts and idler pulleys, port-engine exhaust-manifold gasket leakage, exhaust hoses, bow-thruster bearings, propulsion cutlass bearings, and saltwater-damaged front motor mounts on the port engine.

Main Engines

MAN D2848LE401 Operational Findings

Cold Starting: Both engines started promptly without excessive cranking. A small amount of exhaust smoke was present at startup and dissipated as the engines warmed.

Engine Synchronization: Both engines operated in synchronization without evidence of excessive load imbalance.

Oil Pressure: Approximately 88 PSI port and 86 PSI starboard were recorded during WOT testing.

Cooling Performance: Both engines maintained normal coolant temperatures during cruise and full-load operation.

Turbocharger Performance: Turbocharger response was observed beginning at approximately 1300 RPM. Both engines accelerated satisfactorily with minimal exhaust smoke.

Marine Gear Operation: Both Twin Disc MG-5114A gears engaged smoothly in forward and reverse without abnormal clunking or excessive vibration.

Wide-Open Throttle: Both engines reached approximately 2100 RPM. Confirmation against the manufacturer’s specified rated WOT RPM and the vessel’s propeller loading is recommended.

Detailed Visual Engine Inspection

Fuel Filtration: Racor Twin Turbine Series 900 filter assemblies were inspected. No water was observed and the assemblies appeared serviceable.

Marine Gears: Both Twin Disc MG-5114A marine gears operated satisfactorily during the sea trial.

Seawater Pumps: Leakage was observed at the seal/weep-hole areas on both MAN seawater pumps and the DEUTZ generator seawater pump. Replacement of all three pumps is recommended.

Heat Exchangers: Performance appeared satisfactory and coolant temperatures remained within normal operating range.

Engine Oil Coolers: Inlet and outlet temperatures appeared within expected operating parameters.

Cooling-System Pressure Testing: Both MAN engines and the DEUTZ generator cooling systems were pressure tested to approximately 25 PSI. All three systems passed.

Cooling Hoses and Clamps: Most cooling-system hoses and associated clamps require replacement due to their observed condition.

Fuel, Oil and Transmission Lines: Crimped lines require replacement. Approximately 10–11 lines per engine were identified in the updated inspection notes.

Belts and Idler Pulleys: Replacement is recommended on both MAN engines and the DEUTZ generator.

Port Exhaust Manifold: Water leakage was observed at the port-engine exhaust-manifold area. Removal of the manifold and replacement of leaking gaskets is recommended.

Exhaust Hoses and Clamps: Replacement is recommended on both MAN engines.

Port Engine Front Motor Mounts: Saltwater-related damage was observed. Replacement of the affected front motor mounts is recommended, followed by inspection of mounting hardware and engine alignment.

Propulsion Cutlass Bearings: Movement was observed in the shaft/cutlass-bearing area. Bearing replacement and inspection of shaft condition, couplings, and alignment are recommended.

Bow Thruster: The bow thruster operated satisfactorily during docking. Shaft play was observed during haul-out. Bearing replacement and zinc-anode service are recommended.

Final Surveyor Conclusion

Based on the visual inspection, operational testing, cooling-system pressure testing, and sea trial, the twin MAN D2848LE401 marine diesel engines aboard M/V LE COMPROMIS demonstrated generally favorable mechanical operating characteristics.

Both engines started promptly, maintained normal coolant temperatures, developed strong oil pressure, and reached approximately 2100 RPM during WOT testing. Turbocharger response appeared satisfactory, with minimal exhaust smoke observed after warm-up.

Both Twin Disc MG-5114A marine gears operated smoothly in forward and reverse without abnormal engagement noise or excessive vibration.

The principal deficiencies involve seawater-pump seal leakage, aging cooling-system hoses and clamps, crimped fuel, oil and transmission lines, belt and idler-pulley condition, port-engine exhaust-manifold gasket leakage, exhaust hoses and clamps, bow-thruster bearing movement, propulsion cutlass-bearing wear, and saltwater damage to the port-engine front motor mounts.

Positive Machinery Findings

Both main engines demonstrated satisfactory starting, cooling, lubrication pressure, turbocharger response, and marine-gear engagement during testing.

Required Corrective Maintenance

Replace the identified seawater pumps, hoses, clamps, crimped lines, belts, pulleys, leaking exhaust-manifold gaskets, and damaged port-engine front motor mounts. Address bow-thruster bearing wear and separately evaluate propulsion cutlass bearings and shaft alignment.

OVERALL MACHINERY ASSESSMENT

GOOD — WITH DEEP-DIVE MAINTENANCE AND CORRECTIVE REPAIRS RECOMMENDED

The observed engine and marine-gear performance was generally satisfactory. However, the documented maintenance deficiencies should be corrected to improve reliability and reduce the likelihood of future mechanical failures.

EXISTING CORRECTIVE REPAIR BUDGET

$29,000–$39,000

Includes previously estimated repairs, haul-out charges, and contingency. Additional motor-mount and propulsion cutlass-bearing costs are excluded.
