THE DESIGN OF A SIMULATOR OFFERING TRAINING IN LNG/LPG CARGO HANDLING

The Gas Carrier Course offered at the Maritime Institute of Technology and Graduate Studies, a four-week course, has been used as a model for this paper. This course was entirely classroom-oriented but is now structured to be suppoted by simulation. The course provides the cargo officer with basic understanding of liquefied gas, an introduction of the metric system, conversion tables and other definitions, characteristics of the LNG trade, chemical composition and the classifications of the cargoes, and, before moving on into the more advanced work, basic thermodynamic properties such as vapour pressure, boiling and dewpoint, enthalpy and entropy and an understanding of the use of Mollier diagrams. During the following weeks, components and instrumentation of the cargo handling system are studied as are operating characteristics for the various types of pumps, intrinsically safe electrical circuits, temperature sensors and level gauging. Toward the end of the course, the components and sub-systems are finally married into the overall system and the important area of cargo control is then presented, such as custody transfer, drying, inerting, purging, pre-cooling of pipes, etc. It is when the students have arrived at this level that it is necessary that they be given the opportunity to exercise this knowledge using realistic problems and situations that have occurred on operating gas carriers. The use of a simulator to provide this training now becomes mandatory. It is necessary for the student to be able to operate the system, both through normal loading and also one which might have malfunctions affecting his decisions. With this realistic trouble shooting it is possible to evaluate the student's performance under stress situations. The use of a simulator is the only means by which this training can be safely given.
