A turbine ship engine converts fuel energy into mechanical power using a rotating turbine. Key parts include the compressor, combustion chamber, turbine blades, and exhaust system. It is efficient and widely used in marine propulsion for its high power-to-weight ratio.

Turbine Ship Engine Specifications:

- Size: Typically ranges from 5,000 kW to 80,000 kW, depending on vessel type.

- Grade: Marine-grade turbines, compliant with IMO Tier II/III emissions standards.

- Viscosity: Lubricating oil viscosity ranges from SAE 30 to SAE 50, depending on operating conditions.

- Buoyancy: Not applicable (engine is fixed within the ship's hull).

- Material: High-strength alloys (e.g., Inconel for blades, stainless steel for casings).

Engine Parts Specifications:

- Turbine Blades: Nickel-based superalloys (e.g., Inconel 718), length 0.5m to 1.5m.

- Combustion Chamber: High-temperature steel (e.g., AISI 310), thickness 10-20mm.

- Bearings: Bronze or ceramic-coated steel, viscosity grade ISO VG 68-100.

- Shaft: Forged steel (ASTM A668), diameter 200-500mm.

- Casing: Cast iron or steel (ASTM A48/A216), thickness 15-30mm.
