Designed by Wärtsilä Ship Design, an offshore construction vessel NORMAND INSTALLER was built in 2006 by Ulstein for the Norwegian offshore company Solstad Offshore ASA and the Swiss-based company Single Buoy Moorings Inc (SBM).
The vessel is employed in the installation and maintenance of floating production systems and single-point mooring (SPM) systems around the world. The vessel is thus designed to be extremely versatile in its capabilities based upon the experience of both Solstad Offshore and SBM, and upon anticipated future demands. It has the largest anchor handling winch ever supplied by Rolls-Royce, a moonpool, a 250t capacity A-frame over the stern, helicopter deck and a 250t offshore crane. It has a large working deck aft, with a working area of about 2500m2 on two decks.
The vessel is equipped with a diesel-electric power plant incorporating two Wärtsilä 16V32 diesel generating sets and two Wärtsilä 8L32 diesel generating sets. The 16V32 engines each develop 7680kW, and 8L32 engines each 3840kW, both at 720 rpm. Electric propulsion motors drive through twin Wärtsilä SV105 reduction gears two Lips CPS115 controllablepitch propellers (dia 4.5m) running in Wärtsilä Lips HR nozzles. In addition, Wärtsilä has delivered four CT250M-D tunnel thrusters and an FS225-240/MNR retractable thruster.
