#PartQtyWhat it does
1 Main Diesel Engine 2× 2000–4000 kW each
2 Reduction Gearbox 2× Marine gearbox stepping engine speed down to propeller speed and adding clutch and reverse.
3 Propeller Shaft 2× Forged steel shaft transmitting torque from the gearbox to the propeller.
4 Stern Tube 2× Bearing housing where the shaft passes through the hull, sealed against seawater.
5 Shaft Bearing 4× Line bearing supporting the propeller shaft along its run inside the hull.
6 Controllable Pitch Propeller 2× controllable pitch
7 Steering Gear 1× Hydraulic ram unit turning the rudder stocks in response to bridge helm commands.
8 Exhaust Uptake 2× Insulated duct carrying engine exhaust gas up through the funnel.
9 Seawater Cooling Pump 2× Engine-driven pump circulating seawater through heat exchangers.
10 Oil Seal 4× Spring-loaded rotary lip seal that keeps lubricant inside a housing and dirt out where a shaft passes through, sized to DIN 3760.
