Swire Pacific Offshore Selects MAN B&W

Posted on October 7, 2005

MAN B&W Diesel has been awarded the contract to supply complete twin-screw medium speed propulsion packages for six Anchor Handling Tug Supply Vessels (AHTS). The newbuildings, which will be built by Labroy Shipyard, Batam, Indonesia (Labroy Shipbuilding and Engineering Pte Ltd, Singapore) are to be operated by Swire Pacific Offshore Limited, Singapore.

The 120 ton bollard pull AHTS vessels have been designed by the UK-based IMT Marine Consultants Ltd, with specific optimisation for the worldwide operation of Swire Pacific Offshore activities.

A total main engine output of 2 x 3285 kW will supply the propeller thrust, for a bollard pull of more than 120 metric tons. The ship service speed is optimized for 13.5 knots. The MAN B&W Diesel twin-screw Alpha Propulsion System type 9L27/38-VBS has been specified for the newbuildings. For gear reduction, two MAN B&W Alpha AMG55 gearboxes, type 57VO55EV, offer a speed reduction ratio of 800:141. Additionally, each gearbox is equipped with a 1800 r/min PTO shaft for a 1600 kVA shaft alternator.

The first newbuilding is expected to be launched in the beginning of 2007, and the following vessels are planned to follow at two month intervals.
