LCS Propulsion

• MCS
• DCS

• PPCU
• Portable Propulsion Control Unit

• Data Acquisition Unit
• Interface between consoles and ships equipment, sensors, systems
• 21 of them

• Reduce the speed of the prime mover to a usable speed for their associated water jets
• convert high speed low torque to low speed high torque

• MRG for MPDE
• Uses a multi-disc clutch
• Has 5 plain bearings and 6 roller bearings

to engage and disengage main propulsion diesel engine to its main reduction gear

The purpose of the power take off shaft is to drive the attached water jet drive hydraulic pump

• Cooldown
• Maintenance
• MRG Inspection

• The primary purpose of the built on control oil pump is to ensure control oil (hydraulic pressure) is supplied to the MDC for clutch engagement
• once the MDC is engaged there is very little usage of control oil (only replacing the small amount of oil that is leaked off for clutch cooling)
• the surplus control oil is diverted into the main lube oil supply system

• to support the Built On Control Oil Pump in providing the ASL 95 reduction gear with lubrication oil
• also known as secondary built on lube oil pump

The purpose of the Starting and Standby Pump is to supply control and lube oil to the ASL 95 reduction gear during start up, shut down and emergency operation, and during operation at the lower speed range.

Cooled by raw water
