The tunnel thruster design is based on proven technologies from France and Holland. With innovative effort of the R&D team, full-series ADVANCE tunnel thrusters with own IP have been developed. The development is done to meet continuous operation under severe weather in offshore. So all tunnel thrusters can be applied to continuous working ships such as dynamic positioning operation up to DP3, ice-class ships and research ships. As an integrator, the tunnel thruster system the company delivered is a package including prime mover, starter (normally reduced-voltage starter), hydraulic system and electric control system.
