G-Sim Instructor Station

G-Sim Instructor Station

Liquid Operations Simulator (or Liquid Gas Handling Simulator) developed by GTT Training Ltd., is a highly detailed simulation platform that allows operators to be trained in all aspects of handling Liquid Gas Cargoes on board ship and ashore.  The accuracy and realism of the simulator also allows it to be used for research and operation pre planning purposes.

Using high fidelity mathematical models the system provides very realistic simulation of all the flow and control processes together with the appropriate equipment for the respective liquid gas system(s).  Facilities within G-Sim allow the operator to select the system that is to be used based upon:

  • Vessel size

  • Cargo containment system

  • Propulsion system

  • LNG Cargo composition

Each model includes all the components of a vessel or system that need to be considered in the management of a vessel or shore installation and hence allow any operation that may be undertaken on the real system to be replicated.  Consequently the models allow the full scope of training to be conducted from basic system familiarisation through to detailed problem solving and implementing emergency procedures involving LNG Carriers and LNG Bunkering Operations

Main features of the system are:

  • Designed to run on any PC or tablet using a MS Windows based operating system

  • User interface designed to replicate real systems incorporating all the appropriate controls and information, whilst being simple to use

  • Ability to configure the training environment to suit the requirements of the organisation, instructor or individual.

The flexibility of the system allows it to be used very effectively for:

  • Training

  • Performance Assessment

  • Research including:

    • Pre-running on unusual load patterns

    • Development and verification of operating procedures

    • System design

G-Sim and all the model libraries are approved by DNV-GL in accordance with their Standard for Maritime Simulators Systems (DNVGL-ST-0033), meeting the requirements of Type A & Type S as appropriate

Models currently available include:

  • LNG Carriers

    • Twelve different configurations of LNG Carrier including :

      • Steam Propulsion

      • DFDE Propulsion

      • MEGI Propulsion

  • LNG Bunkering and Fuel Gas Handling

    • The Bunkering module
      Including a LNG Bunkering Barge and the appropriate shore supply and receiving vessel facilities the module allows the simulation of teh operations required on board a LNG supply vessel and all the various types of bunkering operations between different tank types that are likely to be encountered including :

      • Pressurised (Type C) to Pressurised (Type C)

      • Pressurised (Type C) to Atmospheric (Membrane / Type B)

      • Atmospheric to Pressurised

      • Atmospheric to Atmospheric

    • The LNG Fuel Gas Handling System module:

      Designed specifically to support the training requirements for seafarers as identified by the STCW convention as well the undertaking of specific LNG as a Fuel operation courses, the new module includes the vessel’s LNG fuel tanks and the complete fuel gas handling management system, along with all the associated support systems as fitted on the latest LNG fueled vessels, allowing a user to undertake any operation with such a system as on board a real vessel. These operations include preparation and management of the LNG fuel tanks, bunkering from different types of suppliers and the supply of gas fuel to the equipment on board using both compressors and fuel pumps. The functionality also includes the capability to change the type of LNG fuel tank and the composition of the LNG to be bunkered. A CCTV view of the bunker stations may also included.
