The model is based upon a 165,000 dwt “Suezmax” type vessel equipped with fully segregated ballast tanks with a double hull design. The vessel incorporates all the latest requirements of MARPOL 73/78 for vessels of its type.

Detailed description:

  • Number of Cargo Tanks – 12 Cargo + 2 Slop Tanks.
  • Cargo System - The cargo system allows three or twelve grades to be loaded and carried in a completely segregated condition. The tanks are grouped and connected to one of three cargo mains. Each cargo tank is equipped with one main and one stripping suction.  The vessel is equipped with three steam turbine driven main cargo pumps. Each pump can be operated manually but they are also equipped with an automatic stripping system which controls the pump speed subject to the conditions of the vacuum system, suction box and discharge valve. A full steam supply system is provided. The operator may select the required steam supply pressure from the boilers for the cargo pumps or cargo heating system. The resulting load on boilers will in turn affect the oxygen content achieved within the supplied Inert Gas.
  • Inert Gas / Ventilation System - The vessel is equipped with a standard flue gas Inert Gas plant with two 100% blowers. A topup IG Generator is also provided for the supply of small quantities of IG. The deck seal is of the semi-dry type and supply lines are provided to deck, cargo lines, ballast system and pumproom. All the standard interlocks and alarms for such a plant are incorporated.
  • Crude Oil Washing System - The vessels COW system is fitted with both top programmable, and bottom non programmable machines. Indicators operate when the correct drive pressure and flow rate has been achieved. The operator can program the angle of operation on the top mounted machines. A steam cargo heater is also provided for the heating of wash water.

  • Ballast System - The ballast system comprises of a fully segregated ballast system comprising 14 tanks. The system is equipped with two electric ballast pumps and one stripping eductor. Connections are provided from the inert gas supply and into the cargo system.
  • Gas Detection System - The fixed gas detection system allows the continuous monitoring of spaces outside of the main cargo system. Portable instruments are provided for the detection of Oxygen, %LEL and %Vol within the cargo system together with an H2S monitor for use with appropriate cargoes. 

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