Hong Kong's Cheoy Lee Shipyard has handed over the second in a series of five 50m Towing/Anchor Handling Tugs for Teras Offshore in Singapore.

The new AHTS Teras Bethel sailed directly to Batam in Indonesia (dodging a typhoon) where she will enter service. Prior to departure, the vessel and crew were blessed by the reverend Stephen Miller of the Mariners’ Club in Hong Kong.

Designed by Wärtsilä Ship Design Singapore, the capabilities of these vessels include; towing/moving barges and rigs, tanker handling and berthing, anchor handling duties, transporting equipment and materials, external firefighting, maintenance and pollution control.

Construction is to ABS class, with the notation +A1, Towing Vessel E, +AMS, UWILD.

 All five vessels are powered by twin Yanmar 6EY26W diesels, each developing 2610hp at 750 RPM. Power is transmitted to two Berg 2650mm diameter controllable pitch propellers via Twin Disc gearboxes. Free running speed is 13.5knots, with a bollard pull of 69 tonnes.

Maneuverability is enhanced by a 320kW Nakashima TCT-105 electric bow thruster, also with a controllable pitch propeller, and delivering 4.9 tonnes of thrust. Three Caterpillar 350kW 3-phase generators supply onboard power requirements via Teresaki switch and distribution boards. An 82kW, air cooled Caterpillar C4.4 generator serves as a stand-by. There is a capacity of 544 cubic metres of fuel and tankage for 234 tonnes of potable water allows for extended range.

The vessel accommodates a crew of up to 24, in four 4-man cabins, three 2-man cabins and two single cabins for the captain and chief engineer.

The elevated bridge has excellent all round visibility, with both forward and aft facing control stations, each with Bostrom helm seats. Steering is by Jastram, and the full array of navigational equipment is primarily from Furuno.

Towing gear is exclusively from MacGregor in Singapore, including the 75 tonne anchor handling/towing winch, 6 tonne anchor windlass, a rope storage reel, a combination shark jaw and towing pins, two tugger winches and two capstans. The deck crane with 9m reach for lifting the work boat is from Palfinger.

There is also a Zodiac 6-man SOLAS rescue boat with ‘A’ frame launching davit on the starboard side and a work boat on the port side.

Principal Dimensions: 50.00m LOA x 12.60m Beam x 4.50m Draft.
