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
DNV GL certification
This model is certified and approved according to DNV GL’s Standard for Certification of Maritime Simulator Systems ST-033 March 2017.
The simulator is suited for the following training:
- Junior officers in basic cargo operations
- Senior officers in full-scale cargo operations (loading/discharging/ tank cleaning /venting)
- Senior officers and captains in advanced cargo-handling operations
The training objective of this model is to understand the total cargo- handling operation. Specific training objectives include the following:
- Familiarization with all parts of the cargo system
- Planning a cargo-loading or discharge operation using booster pump and cargo heaters when required
- Lining up for loading and ballast handling simultaneously (check atmosphere)
- Controlling the flow into each tank and the trim/list of the ship
- Controlling the atmospheric pressure and temperatures
- Topping up and finalizing loading
- Loaded voyage
- Preparing and lining up for discharge
- Starting up discharge, one or more grades
- Emptying and draining tanks
- Finalizing departure ballast
- Inerting tanks after docking, and cooling down before loading
- Inerting and venting tanks for inspection/docking
