At Nozzle Marine Engineering Services LLC, we specialize in complete marine engine overhauls to ensure optimal performance, extended service life, and compliance with OEM and class society standards. Our overhaul process follows a strict, step-by-step approach led by certified engineers and technicians — available both in-house and onboard.

We begin every overhaul with the systematic dismantling of the engine and its components. Our experienced technicians perform a detailed visual and technical inspection to identify wear, damage, and operational issues. Each component is measured and assessed for further reconditioning or replacement, ensuring no fault goes unnoticed.



Once inspected, all reusable components undergo professional reconditioning. This includes cleaning, polishing, machining, and surface treatments where required. Our reconditioning process restores key engine parts to OEM standards, ensuring durability and cost-effectiveness without compromising performance.



These are critical components in your engine’s performance and reliability. We carry out full overhauls of cylinder heads, liners, pistons, and crankshafts, including:
Valve and seat refacing
Liner honing or replacement
Piston ring renewal
Crankshaft journal polishing and alignment checks
Each component is reassembled to exact tolerances for smooth engine operation.



Accurate fuel delivery is essential for engine efficiency and emission control. Our team conducts fuel injector calibration and testing to verify spray patterns, injection pressure, and flow rates. We also inspect and clean fuel pumps, nozzles, and high-pressure lines to restore precise fuel delivery and optimal combustion.



After all components are reconditioned and verified, we carry out precision reassembly of the engine. Our technicians follow OEM guidelines and torque specifications during reassembly. Commissioning includes:
Alignment and clearance checks
Engine test runs
Vibration, oil pressure, and temperature monitoring
Final performance verification
This ensures your engine is ready for full-duty operation upon completion.



We offer flexibility through our fully equipped Dubai workshop and mobile service units for onsite repairs. Whether your vessel is docked or offshore, our team can deliver complete overhaul services with the same level of care and compliance—reducing downtime and avoiding costly transport.
