The model is based upon a 19,000 dwt 1998 built Type 1 Chemical Tanker equipped with fully segregated cargo tanks and pipelines allowing the vessel to load, transport, and discharge multiple parcels with complete segregation.

Detailed description:

  • Number of Cargo Tanks – 34 independent tanks
  • Cargo System - Each cargo tank is equipped with its own hydraulic cargo pump (Framo cargo system), cargo heater(s) and the associated main and stripping cargo pipelines. Tanks can be interconnected if required via connections provided at the cargo manifold. Connections to over side are also included.
  • Controls for the cargo pumps operate in the same way as real systems. A hydraulic supply system is provided which supplied both the cargo pumps and the two ballast pumps. A Nitrogen supply for use during stripping operations is also provided. Indicators allow the monitoring of cargo parameters including temperature at three levels, tank pressure and the liquid level.
  • Ventilation System - Each cargo tank is fitted with individual pressure relief devices. Eight tanks are equipped with the ability to adjust the settings of these devices to suit the carriage of cargoes with a high vapour pressure. Connecting pipelines allow the tanks to be interconnected or vented via one of the six vapour manifolds. All tanks can be maintained fully segregated if required. 
  • Cargo Heating - The vessel is equipped with two means of heating the cargo within the tanks, fresh water or thermal oil. All the heaters are mounted on deck and supplied from the engine room. The main heating for both cargo systems is supplied by a primary thermal oil circuit. 
  • Tank Cleaning - The cargo tanks are able to be washed using fresh or sea water. A heater is also provided if hot water is required. Each tank is equipped with an appropriate number of programmable fixed washing machines. The operator may program the machines with respect to the pitch and the min and max angle of operation. Water is supplied by the use of electric pumps and facilities allow the supply of fresh water from the FW tanks to be topped up. 
  • Ballast System - A ballast system comprising 13 fully segregated tanks is included. System is supplied by two hydraulically operated pumps and is also equipped with a stripping eductor. Whilst operations are in progress the operator can monitor the effects on the trim and stability of the vessel together with all the tank conditions.

The model represents all the controls, equipment, machinery, instrumentation, alarms and shutdowns associated with this type of vessel related to the carriage of chemicals.
