Self propelled Jack up vessel

After being involved in several projects related to (semi) jack-ups and jacking systems, Vuyk produced the complete design, from concept to basic design, of a wind turbine installation jack-up for a Taiwanese customer in cooperation with IHC sister units. The scope included assistance in defining the functional specifications and the hull, legs and jacking system design up to class approval.

The vessel will be capable of transporting and installing equipment such as 4 x typical 3.6/4.0 MW, 2 x typical
5.0/6.0 MW offshore wind turbines or a 700 t jacket. Furthermore, it can be utilised as a liftboat in the oil and gas market. The basic ABS-class approved design will be ready in the third quarter of 2015.
