K-Sim® Cargo LPG/Ethylene

Operators of LNG tankers must maintain control at the start of loading and discharging.

If the cargo boils off too fast or the tank is cooled down too fast, pressure or vacuum can lead to extreme temperatures damaging the tanks or the hull structure. LPG tankers may also act partly as oil product tankers (naphtha) and chemical tankers (ammonia), and so can our model.


Our K-Sim Cargo-LPG/Ethylene model is based on a real LPG/Ethylene tanker. The model consists of three double independent tanks type C able to take fully refrigerated or semi-pressurized cargoes. A compressor room is fitted with three compressors and two R22 plants. The ship can take two separate grades. Booster pumps and cargo heaters are situated on deck. It is fitted with a separate ballast system, a nitrogen generator, and an inert gas generator with dryer system. The cargo temperature and environment data may be set individually. The tank atmosphere and temperature data are calculated continuously.



The LNG-M model meets the requirements of STCW section A-II/1, A-II/2, A-II/3, A-III/1, A-III/2, and A-V/1. 
These sections cover:

Planning and ensuring safe loading

Care during the voyage and unloading of cargoes

Trim, stability, and stress to maintain seaworthiness of the ship
