LOC deploys the SafeTrans software for the safe design and operation of marine transports and heavy-lift operations. The software can simulate large vessels, barges, heavy-lift vessels or tug and tow operations.
What is SafeTrans?
SafeTrans is a voyage analysis tool for the design of heavy lift transports developed as a Joint Industry Project. The inputs to the SafeTrans software are the ship’s location and voyage route details including safe havens, bunker stops and forbidden areas, the hull definition of the vessel, the amount of fuel onboard and the number of personnel onboard. The vessel seakeeping response operators can be calculated by the software or may be input. The software uses the actual environmental conditions expected along the route based on a hind cast dataset to output the vessel motions. Outputs include forces and accelerations at different locations of the vessel and/or its cargo as well as transit times. This software was approved as an engineering tool for marine transports and operations by DNV in 2007.
The software is suitable for the analysis of major transportation projects. For example, the Yamal project is characterized by numerous transports from Asia to Europe and on to the Arctic on specialist ice breaking module carriers. All marine transport of modules, pipe racks and heavy equipment by module carriers can be simulated by the software. The outputs will inform the suitability of the designs of sea fastenings and provide assistance in route scheduling by examining the voyage duration.
Benefits of SafeTrans in projects such as Yamal, the software can take as inputs the vessel types specific to this project and calculate the vessel response in each sea, it is able to accommodate the long distance transit from the far East and include the environmental conditions specific to areas such as the Bay of Biscay and the Norwegian Sea. A core advantage of the software is in its probabilistic approach; this produces a more realistic output as well as the uncertainty associated with that output to better inform its reliability.
A further advantage of SafeTrans is that it can calculate realistic transit times that include the effect of weather, speed reduction, vessel characteristics and cargo. The voyage duration can be output in terms of the probability of obtaining a suitable weather window within a specified timeframe. The voyage duration helps with the voyage plan and aids scheduling to optimise predicted weather and ice windows. There is an additional option to include typhoon risk during sailing.
