Ulstein Group has designed and built two new anchor handling and offshore support vessels with a new breed of hybrid propulsion system for shipowner Olympic Shipping. The new Ulstein hybrid propulsion concept has taken the potential of the rather complex hybrid propulsion concept to completely new levels of performance.

The Ulstein hybrid propulsion concept combines the best properties of both DE and DM into one system. This includes DM attributes of higher efficiency and better performance at high loads, along with the DE trait of excellent fuel consumption at low loads. Hybrid propulsion is therefore the perfect match for the operation profile of anchor handling vessels like the Olympic Zeus and the Olympic Hera.

The Ulstein Group claims that combining the medium-sized DM and DE systems into one large hybrid propulsion system proves to both take up less space and be less expensive than a large DE system.
