ULSTEIN'S NEW OFFSHORE STARS PLAY ANCHOR HANDLING AND SUPPLY ROLES

Star Sirius and Star Spica, the first vessels of the Ulstein type UT734 supply vessel, developed from the UT704 design, have been delivered. These vessels, which have propulsion power 9000 bhp, are said to be capable of undertaking the same work as other 12000 bhp vessels. The deadweight, at 2000 tonnes, is 200 tonnes higher than for the earlier class, and to accommodate this the beam has been increased to avoid increasing the draught; as a result there is a slight drop in speed. The redesign of the hull, together with a large propeller, has enabled a bollard pull of 108 tonnes to be achieved. An Ulstein Mansi FCM electronic control system is installed on the bridge; in the sailing mode this controls the main propellers and rudders, and in the manoeuvring mode also the thrusters. A control panel with a mimic diagram for cargo handling is also located on the bridge. A triple-drum waterfall winch performs both anchor-handling and towing duties. Principal particulars are: Length oa/bp 65.0/56.4 m; Breadth 14.5 m; Depth 7.4 m; Draught, design 5.18 m. The capacities of the tanks for fuel oil, drill water/ballast, brine, potable water, dry-bulk mud, rig chains, and liquid mud are listed, and there is a general-arrangement drawing.
