The Main Engine Vessel is the primary propulsion system of a ship, generating power to move the vessel through water.

Engine parts include the cylinder block, pistons, crankshaft, fuel injectors, and turbochargers, which work together to convert fuel into mechanical energy.

Regular maintenance of these components ensures efficient operation and longevity of the marine engine.

Main Engine Vessel:
Size: Varies by model (typically 5m to 30m in length)
Grade: Marine-grade steel (ASTM A131, AH36/DH36/EH36)
Viscosity: N/A (structural component)
Buoyancy: Dependent on hull design and displacement
Material: High-tensile steel, aluminum alloys, or composite materials

Engine Parts:
Size: Varies (e.g., pistons: 100mm–500mm diameter)
Grade: Cast iron, forged steel, or aluminum alloys (SAE J429, ASTM A536)
Viscosity: Lubricating oil SAE 15W-40 or 20W-50 (for moving parts)
Buoyancy: N/A (internal components)
Material: Steel alloys, bronze, or polymer composites (for bearings/seals)
