Jun 17, 2010

In March, Cheoy Lee Shipyards handed over the first in a new series of Multi-Purpose offshore commercial craft. The second vessel in the new series, for the same owner, has now been delivered in early June. PB Konui is designed by Wartsila Ship Design Singapore Pte. The operational requirements of this vessels requires anchor handling, tanker handling and berthing, towing barges and rigs, maintenance and pollution control, supply duties and fire fighting capabilities. The vessel is constructed to ABS class, with the notation +A1, (E), +AMS, Towing Service. The remaining two vessels in this construction batch of four are scheduled for handover in late 2010.



The vessel is powered by two Yanmar 6EY26 diesels, each developing 1920 Kw @750 RPM, driving two Berg BCP690, 2650mm dia. propellers in nozzles via Reintjes LAF 2346L gearboxes with a 3.5:1 reduction ratio. Maneuverability is enhanced by a 320kW Nakashima TCT-105 electric bow thruster. Three Caterpillar 350kW three phase C18 generators supply all onboard power requirements via Teresaki switch and distribution boards, with an 82kW, air cooled Caterpillar C4.4 serving as a stand-by. 500m3 of fuel and capacity for 240 tonnes of potable water allows for extended range.

The vessel accommodates a crew of 30, in six 4-man cabins, two 2-man cabins and single cabins for the captain and chief engineer on the forecastle deck level. The elevated bridge has excellent all round visibility, with both forward and aft facing control stations, each with a Bostrom helm seat. Steering is by Jastram, and a full array of navigational equipment is primarily from Furuno.

Towing gear is exclusively from Plimsoll in Singapore, including the anchor handling/towing winch, anchor windlass/towing winch, two rope storage reels, shark jaw, towing pins, tugger winches and capstans. The deck crane for lifting the portside rescue boat is from Palfinger.

PB Konui departed on her own bottom from Cheoy Lee’s Kowloon shipyard, en route to Freemantle, Australia where she will enter into service.
