LNG Carrier Cargo Operations Simulator (X-DF)

Membrane (GTT NO96) LNG carrier cargo-operations simulator for a vessel propelled by a WinGD X-DF low-pressure dual-fuel two-stroke main engine. Covers the full cargo cycle — cool-down, gassing-up, loading with vapour return, laden passage boil-off-gas management, discharging and stripping — together with the low-pressure Fuel Gas Supply System (LD/HD compressors, gas heater, GVU, forcing vaporiser), Gas Combustion Unit, IBS/IS nitrogen, inert gas, gas detection and the cargo manifold with ship-shore ESD, per IGC Code 2016, SIGTTO and STCW A-V/1-2.

Systems Training module type

Systems & scenarios covered

Full cargo P&ID with four membrane tanks, liquid/vapour/spray headers, deepwell cargo pumps and valve transit physics.

X-DF low-pressure Fuel Gas Supply System: LD compressor, gas heater, master gas valve, GVU and forcing vaporiser at ~16 barg.

Boil-off-gas management on laden passage — engine fuel-gas consumption vs Gas Combustion Unit disposal.

Cargo manifold with ship-shore ESD link, loading arms and vapour return.

IBS/IS nitrogen pressurisation, inert gas / dry-air generation and fixed gas detection.

Emergency scenarios: rapid BOG / high tank pressure, overfill and ESD drill.
