Ulstein has sold design and equipment packages for four ocean going tugs to Niigata Shipbuilding & Repair in Japan. The vessels will be built for the Dutch company ALP Maritime Services.
The vessels are primarily designed for towing large structures over long distances. This is a new market for Ulstein and so far, the contract represents the highest value in one single contract for Ulstein Design & Solutions. The vessels of the SX157 design are developed especially for this project in close collaboration with ALP. They are expected to deliver in the range of 300 ton bollard pull, and will be 88.9 metres long and 21 metres wide.
Apart from the design, Ulstein is also responsible for the deliveries of main components, such as engines, thrusters and propellers, winch, power distribution and thruster drives, control system and communication system.
ALP Maritime Services is a subsidiary of Teekay Offshore Partners L.P. The vessels will be built at Niigata Shipbuilding & Repair, a yard in the MES group (Mitsui Engineering & Shipbuilding Co.). The vessels are intended for worldwide operations, and are planned for delivery by Q4 2015 and Q1 2016.
