A significant delivery for the Cheoy Lee shipyard in Hong Kong was the completion of Teras Ariel, the first of a series of five 50m anchor-handling tugs for Teras Offshore in Singapore. Designed by Wartsila Ship Design Singapore, the vessels are intended for towing barges and rigs, ship handling, anchor handling, transportation, fire-fighting, maintenance and pollution control duties in Batam, Indonesia.
All five vessels will be powered by twin Yanmar 6EY26W diesels, each developing 2,610bhp at 750rpm. Power is transmitted to a pair of Berg 2,650mm diameter controllable pitch propellers via Twin-Disc gearboxes. A free running speed of 13.5 knots and a bollard pull of 69 tonnes was recorded on trials. Towing gear is from MacGregor in Singapore, including the 75-tonne anchor-handling/towing winch.
Duke II for Russian waters twin-screw tug
The Dutch shipyard Gebr Kooiman of Zwijndrecht has delivered Duke II, a powerful twin-screw anchor-handling tug for use in Russian waters. Duke II was ordered in April 2012 by Russian company Probus Mare Marine Ltd to conform to Ice 1A Super class rules to operate in Novaya Zemlya, an archipelago north of Russia in the Arctic Sea.
Due to the large quantities of ice, the area is navigable for just a few months of the year, making it essential that the vessel works faultlessly during that short period. Duke II is similar to several twin-screw tugs built by Kooiman for Dutch operators which are engaged in a wide range of offshore and seagoing duties, and measures 34.3m overall by 11m breadth, and a mean draft of 4.05m.
