Canadian ship designer Robert Allan Ltd (RAL) says that Shanghai Harbour Fuxing Shipping Service Company Sanlin Shipyard has successfully completed a 3680kW RAmparts 3200-W tug 'Hai Gang 501' which will provide service at Shanghai Port.

This will be the first RAL tug to operate in China’s busiest port which has also been the world’s busiest container port for the last decade. As part of the RAmparts series, this new tug is designed for berthing and unberthing large vessels in harbour and is capable of coastal towing services due to its sea keeping performance. The design was altered slightly to suit the selected machinery and equipment and the accommodation arrangement that the crews are familiar with.

Each of the tug fleet owned by Shanghai Harbour Fuxing Shipping Company is named Hai Gang which translates as “harbour” in the Chinese language. Sanlin Shipyard had built more than 10 RAL-designed tugs for its domestic and international clients before building Hai Gang 501 for its mother company.

The 32m vessel’s accommodations are outfitted to MLC compliant standards for a crew of up to 10. Main propulsion comprises a pair of Niigata 6L28HX engines, each rated at 1840kW at 750 rpm, driving a cardan shaft system to a Niigata ZP-41A Z-Peller propulsion unit with a 2,600 mm diameter fixed pitch propeller. Deck machinery comprises a Karmoy hawser winch on the bow, spooled with 250m line on each drum, with twin anchor windlass at bow beside hawser winch and a Karmoy towing winch provided on aft deck.

The tug was designed and constructed to CCS Notation ★CSAD, Tug/Fire Fighting Class 1; Coastal Area; ★CSMD, IBS. On trials it achieved 68.2t bollard pull, ahead and a free running speed, ahead, of 13.3 Knots
