Navis Delivers DP2 System for Largest Asian FSV

Dynamic positioning control systems from Navis Engineering have met performance expectations set out in the sea trials of the 62m aluminium fast supply vessel (FSV) FOS THOR.  Designed by, built for and managed by Fast Offshore Supply Pte Ltd (FOS), of Singapore, FOS THOR is equipped to meet the highest industry standards and is the largest vessel of its type to be built in Asia.

FOS THOR features four controllable pitch propellers (CPP) and two bow thrusters, a configuration ensuring superior DP performance, where fast crew vessels are commonly specified featuring fixed pitch propellers or water jet propulsion.

The vessel features a unique loitering mode, allowing it to remain on station using only one propeller and one bow thruster. This helps to reduce fuel consumption significantly during waiting periods near the rig. In common with other vessels equipped with the Navis DP system, this ‘hold area’ capability also reduces system wear and tear.

The algorithms used by the Navis DP system enable rapid DP operation start-up, accruing additional fuel and operational cost savings. Furthermore, the Navis DP system is the most compact now on the market, representing a key advantage within the space-constraints of the FSV bridge.
