SafeTrans as a Service!


Voyage simulations are an important aid in design choices, operational decisions, risk assessments, schedule predictions and many other activities. With increasing standards regarding safety, fuel consumption/CO2 emissions and scheduling accuracy, combined with increasing computational power, the significance of simulations in the maritime sector’s daily practice keeps growing.


Schematic overview of cloud based computing W


ithin a Joint Industry Project MARIN has developed SafeTrans as a voyage simulation tool for


designing and analysing heavy cargo transports around the world. The SafeTrans user can configure ships, loading conditions, routes and voyages to use in long-term time-window simulations that predict speed, motions and cargo lashing forces at specified time intervals.

24 report


The simulations include environment effects such as ocean currents, wind and waves. These environment factors are obtained from weather databases. Apart from their direct influence on motions, SafeTrans features a Captain’s Decision Mimic (CDM), which resembles the behaviour of captains, including their decisions about the best way to operate safely and maintain the operation planning. The CDM uses weather forecast data to choose an alternative route


(see image) or to seek shelter at a port close to the route. Additionally, the CDM can decide to reduce engine settings in case motions become too strong.


Towards a web-based application Until now, SafeTrans is a Java-based desktop application, installed locally on the user’s computer. In 2020, a major refactoring of the software has been set in motion. As one of MARIN’s first software tools, SafeTrans now becomes a web-based application that will run as a service on a server. The user can access SafeTrans with a local browser but can finally also integrate (parts of) SafeTrans in their own software. This step offers many advantages, for instance the availability of (parallel) computational power and data storage. With simulations running on a secure and powerful server, rather than on local laptops, more simulations can be conducted with higher quality results.
