Introduction

The intention of this Manual is to supplement any Marine Engineering Knowledge course that contain Steam Knowledge component. The exercises will bring hands on element into theoretical study with high degree of fidelity. It would be particular useful to the students involved into Marine Engineering Cadet Program in their year 3 and 4 of studies.

It is assumed that students are familiar with the work station keyboard lay out, function keys, starting up procedure, managing alarms and saving exercises from the previous experience with MC 90 Simulator.

Propulsion Plant Model

The ERS SP Dual Fuel simulate a large Liquefied Natural Gas carrier with a steam turbine propulsion plant modeled with fixed pitch propeller directly driving a single propeller.

Main Turbine

KAWASAKI UA-400 Cross compound, impulse, double reduction geared marine turbine.  This unit consists of one high pressure turbine, one low pressure turbine including astern elements, maneuvering valve unit and reduction gear.

Output at MCR                   36.800 PS

Revolution HP Turbine    4990 RPM

LP Turbine    3294 RPM

Propeller       88 RPM

Steam Pressure                 60 bar

Steam Temperature         510 C

Main Boiler

Mitsubishi Heavy Industries    56/49 (MB-4B-NS)

Maximum Evaporation    59.500 kg/h

Normal Evaporation         49.000 kg/h

Steam Condition               61 bar super heated steam at 515 C

Safety Valve Settings

Drum High Set    78.0 bar

Superheater         64.5 bar

Ship electrical power generation particulars: 

• 2 turbine generators rating at 450 V, 60 Hz, 3450 kW
• 2 diesel generators rating at 450 V, 60 Hz, 3450 kW

One turbine generator is used during normal sea going conditions.

Two generators are required when:

• Maneuvering
• Cargo loading
• Cargo discharge
