LNG LCHS – Course duration 5 days

The LNG Liquid Cargo Handling Simulator (LCHS) practical and theoretical training has been developed keeping in mind IMO model course 1.36 and SIGTTO standards. The simulator will provide 360° learning for the students as it is covering all the operational aspects of a LNG vessel.
Interlock for cargo pump, spray pump, ballast pump, LD compressor and HD compressor have been incorporated in the simulator.
Important alarms and trips have been include in the simulator to give students realistic feeling of the operations.

The LNG (Membrane Containment) simulator model is based on Mark III design and incorporates all the appropriate design features as found on the real DFDE vessel. This particular vessel design incorporates four cargo tanks, together with compressors, heaters and vaporisers as required to allow all operations to be conducted.
Segregated ballast system is part the simulator, including calculation of online ship stability i.e vessel’s list, trim and draft.
Simulator is covering the below operational cycles as well as operation of various cargo auxiliary system and ESD system:

  • Pre-docking Operations Simulation
