System Initialization

System Setup
Each student station shall be assigned one of the available ship or jetty models, depending upon the training program to be followed.

Model options available:

• A separate model for each student
  This will allow each student to operate the ship/jetty on his or her own.
  
• One model across all stations
  Actions on one screen will affect all stations, creating a control room atmosphere with the potential for team training.
  
• Two or more models across a number of stations
  Students, grouped in two's or three's, combine their experience and problem solving abilities when undertaking complicated exercises.
  
• Linking two or more models and stations directly
  This enables ship/ship or ship/terminal exercises to be conducted.

Cargo Selection
Cargo selection is a function of the model chosen.

For petroleum products, the instructor can select from a range of 10 grades, which he can modify at any time. The grades are defined by density, viscosity, molecular weight and volatile fraction. Any grade can be assigned to any tank or pipe.

For LPG cargoes, the instructor selects from the range of refrigerated cargoes available, including Propane, Butane, Ammonia, Vinyl Chloride Monomer, Butylene, Butadiene, Polypropylene and Ethylene. Pure cargoes or mixtures can be put in any cargo tank.

LNG cargoes can be adjusted with respect to the composition relating to quantity of Methane, Ethane and Propane.

Chemical cargoes are selected by the student from within the model from a list of up to 34 different cargoes previously defined by the instructor. The various cargoes are defined by density, viscosity, molecular weight and the appropriate volatile fractions.

When the models are not linked, loading or discharging is conducted to a 'dummy' source or sink of cargo whose compositions are fixed, but pressures can be set. When linked the commodities in the models are transferred directly.

Exercise Selection
Initial conditions for an exercise can be set up in two ways. The instructor may select a saved 'snapshot' (scenario) from the snapshot library in use. Any one library can contain up to 75 conditions and there may be multiple libraries stored if required.

Alternatively, an existing snapshot may be modified to create a particular condition. This is done using the 'instructor only' pages. Typically this may involve redefining some or all of the following: liquid levels, temperatures, pressures, liquid or gas compositions, oxygen concentrations, valve positions and equipment status.
