The 15 meter Sea Puffin Daughter Craft offers the same wave height performance as a 20 meter crew transfer vessel, with less than half the fuel oil consumption.
The vessel's great performances are made possible by the ship type: Surface Effect Ship (SES), also known as air cushioned catamaran or side hulled hovercraft. She has two side hulls like a catamaran, but has flexible rubber sealing fore and aft between the hulls. Fans blow air into this air cushion between the hulls and rubber seals, and partly lifts the vessel up and out of the water.
This provides reduced contact with the water, and therefore allows for low fuel oil consumption . The air cushion pressure is controlled by valves. These are also used for motion damping and especially while accessing offshore structures. Using this motion damping, the Sea Puffin can access offshore wind turbines in wave heights as if she had been a significantly larger vessel. The first of class, Sea Puffin 1, has proven safe turbine access in up to 1.75m significant wave height .
