Ofcourse it's not unique a vessel of this size with cranes who can lift 240 metric tonnes in pair, but this type is specially designed for the lifting capacity, the service speed with a relative low fuel consumption. This type has a service speed of 18 knots with a fuel consumption of 14 ton per day.
