KOTUG is the inventor of the Rotortug®, which uses a triangular propulsion configuration to provide improved vessel safety, power, efficiency and manoeuvrability. It provides total control with maximum redundancy and superior safety. The Rotortug has been recognized by ports and energy majors as a risk mitigation tool at ALARP (As Low As Reasonable and Practicable).

Infield Support Vessel ISV

The Infield Support Vessel is specifically designed to support FLNG tanker berthing and offshore operations, including emergency response. The propulsion configuration enables the operator to continue to work longer in higher significant wave heights, always in control of its own tug and the assisted object. The ISVs are purpose-built to meet marine services requirements unique to FLNG Shell Prelude and the ConocoPhilips Bayu Undan Field.
