China's Sanlin Shipyard has delivered a new harbour tug to the Port of Shanghai.
Designed by Robert Allan Ltd, Hai Gang 501 ("Harbour 501") will be used by Sanlin's sister company Shanghai Harbour Fuxing Shipping Company for berthing/unberthing, coastal towing, and firefighting duties in China's busiest port.
The tug has an LOA of 32 metres, a moulded beam of 12 metres, and a maximum draught of 5.29 metres. There are also MLC-compliant accommodations for up to 10 crewmembers including six single cabins and a pair of two-person cabins in the deckhouse and lower deck.
Main propulsion for the tug comprises a pair of Niigata 6L28HX main engines, each rated 1,840 kW at 750 rpm. These drive cardan shaft systems connected to two Niigata ZP-41A propulsion units with 2,600-millimetre fixed-pitch propellers to give the tug a bollard pull of 68 tonnes and a free running speed of 13.3 knots.
The deck machinery comprises a Karmoy hawser winch on the bow, spooled with a 250-metre line on each drum. There is also a twin anchor windlass at the bow beside the hawser winch and a Karmoy towing winch provided on aft deck.
