A cutting-edge liquefied gas (LG) cargo simulator has been installed at the SIU-affiliated Paul Hall Center for Maritime Training and Education.Developed by Transas, a highly regarded company, the simulator offers comprehensive training in LG familiarization, LG specialization and LG safety.
“The simulator is a competency- and assessment-based training system,” noted J.C. Wiegman, assistant director of training at the Paul Hall Center, which is located in Piney Point, Md. “What this means for students is they will learn or hone the ability to load and unload a vessel with liquid gas cargo. This simulator has a lot of features. It’ll help them with system alignment, cargo-pump operation, loading and discharge alignment, the ballast system, inert gas system and all the auxiliary systems necessary to complete the evolution, whatever the operation may be. It also will help students understand the volatility of the cargo.”
The LG simulator’s components are wide-ranging but thorough. For instance, there is a segment covering load-control systems with sub-categories as follows: trim, draft, heel and stability; shearing force; bending moment calculation; cargo and ballast-level calculation; oil temperature effect on ullage (unfilled space in a container of liquid); and trend operation.
When utilizing the simulator to study cargo plan overviews, students also will learn about cargo operations planning, cargo type control, cargo data control and alarms in abnormal situations.
Additional topics that will be taught by using the simulator include the following (among others):
Ballast system (ballast operation, gravity flow, flow animation and valve dynamics); after-peak part of cargo system (discharge, loading, pump activity, striping pumps and emergency procedures); terminal connections (discharge, loading, flow animation, terminal connection, berth, cargo type selection and emergency procedures); inert gas plant (inert gas generation; gas cooling, drying and blowing; gas freeing operation and auxiliary operation); inert gas distribution line (tank inerting, in-tank atmosphere control, and pressure breaker operation); load control system (shearing force, bending moment calculation, cargo and ballast level calculation, oil temperature effect on ullage, and trend operation); cargo plan overview (cargo operations planning, cargo type control, cargo data control, and alarm in abnormal situations); and forepick part of cargo system (discharge, loading, flow animation, pump activity, striping pumps and emergency procedures).
