ACCOMMODATION JACK UP UNIT

The ACJB is a dedicated accommodation Jack-Up design based on our series of Jack-Ups. The jack up is fitted with diamond shape type footing which provides the seabed fixation required to operate all year round in a harsh environment condition (North Sea). The represent design consists of a triangular pontoon-shaped hull with a large accommodation deckhouse arranged at the forward end of the unit and a free working deck aft, three open truss legs of 153.4m with spudcans and three Gusto MSC rack and pinion type elevating and fixation systems.

The five stories accommodation deckhouse is arranged around the forward leg and provides permanent accommodation, catering and recreation facilities for 400 persons to UK standard. Three marine type diesel-hydraulic cranes are equipped to cover the working deck and service for the adjacent platform. The helicopter deck is situated at the forward end of the unit. The helicopter deck allows for use of an AW101 helicopter, the largest helicopter used in North Sea area presently.
