Siport21 has significantly strengthened its advanced training offering with the introduction of full RotorTug® simulation capabilities at its Maritime Simulation Center. This major upgrade is powered by Kongsberg Maritime’s cutting-edge K-Sim® platform and includes the installation of a third azimuth thruster control on the real-time ship simulation bridges.
This enhancement enables highly realistic modelling and manoeuvring of RotorTug type vessels — characterised by their unique triangular propulsion configuration with two forward azimuthing thrusters and one aft. Renowned for superior manoeuvrability, high redundancy and exceptional indirect towing performance, RotorTugs are among the most sophisticated assets in modern towage operations.
The new simulation capability is the result of extensive in-house development by Siport21’s team of naval engineers and 3D modelling specialists. Combining Kongsberg’s validated numerical models with Siport21’s hydrodynamic characterisation, the Center now offers a high-fidelity environment that accurately reflects the operational behaviour of the three azimuth tugs, even in the most demanding scenarios including escort operations, confined space manoeuvres and indirect towing.
Ensuring maximum realism, the RotorTug model underwent a rigorous validation campaign conducted by an expert tug master and trainer from KOTUG, towage and maritime company. Their feedback enabled precise fine tuning of the model, resulting in an exceptionally reliable and operationally representative simulation tool.
“With this upgrade, we can now offer one of the most advanced and realistic RotorTug simulation environments available,” said Raul Redondo, Manoeuvring and Nautical Studies director at Siport21. “This capability enhances the quality and depth of our training programmes while allowing operators to safely familiarise themselves with complex manoeuvres and the unique handling characteristics of these innovative vessels.”
The new RotorTug simulation module is now fully available for advanced tug master training at Siport21 Maritime Simulation Center for operational assessments and demonstrations of enhanced towing and manoeuvring performance in a safe, controlled and virtual environment.
