'Hinewai', a ship handling tug built to the RAmparts 2500-CL design from Robert Allan Ltd (RAL) of Canada, recently arrived in her home port of Timaru on the South Island of New Zealand after a 30-day voyage on her own bottom from China.

The vessel will commence operations for PrimePort Timaru, the first owners of a vessel built to this modern ship handling tug design.

The RAmparts 2500-CL tug is an evolution of RAL's successful RAmparts 2500-W design with additional updates for the marketing objectives of the builder, Cheoy Lee Shipyards of Hong Kong.

The hull and skeg of the RAmparts 2500-CL have evolved to provide improved manoeuvring and side-stepping capabilities. As with all RAmparts series vessels, the hull has been optimised for maximum thrust and bollard pull, while maintaining excellent manoeuvring and sea-keeping. A half-raised forecastle deck helps to keep the working deck safe and dry, while a gently rounded deck line in plan ensures the tug can safely and easily come alongside and distance itself from an escorted ship at speed. Most importantly, the characteristic double chine stern characteristic of RAL designs ensures that the tug can run astern at high speeds and maintain good control, directional stability and a dry working deck.

RAL says that the design is highly flexible allowing for a multitude of powering options, deck machinery arrangements, and outfitting choices such as off-ship firefighting. Hinewai has been outfitted to PrimePort’s requirements with a split drum winch and dual aperture staple on the foredeck, a towing hook and deck crane on the aft deck, and a propulsion system delivering in excess of 60 tonnes bollard pull.

The Hinewai was designed and constructed to Lloyd’s Register notation: ✠100A1 Tug, ✠LMC, ✠UMS, IWS. Principal particulars are: Length oa 25.4m, Beam, moulded 11.8m, Depth, moulded (hull) 4.60m, and Maximum draught 5.05m.
