CHEOY LEE DELIVERS FIRST OF RAL TUG PAIR TO HONG KONG OWNER

Wednesday, August 26, 2020 

Canadian designer Robert Allan Ltd (RAL) says that the ‘Hai Kun’, a RAL RAstar 3200-CL tug built by Cheoy Lee Shipyards, first of a two-vessel order, was recently delivered to Yiu Lian Dockyards of Hong Kong.

On sea trials the Hai Kun achieved 88t bollard pull and a speed of 13.5 knots at 100% engine MCR. This delivery marks the 21st vessel built and delivered by Cheoy Lee to the same basic design. Modifications in this case were implemented to this hull to accommodate both the owner’s selected Niigata propulsion package and the required escort capability of the tug. This included a redesign of the skeg and simulations using RAL's in-house CFD capability to confirm the tug’s expected escort performance. Other modifications to accommodation layout, etc. were made to suit the owner’s preferences. The Hai Kun will shortly be joined by sister tug Hai Peng.

The Hai Kun is 32.0m long. 12.8m beam and of 492gt. The tug was designed and constructed to Lloyd’s Register notation ✠100A1 Escort Tug, Fire Fighting Ship 1 (2400 m3/hr) with water spray, *IWS, ✠LMC, Ship Right IHM.

Main propulsion for the tug comprises a pair of Niigata 8L28AHX main engines, each rated at 2574kW at 750 rpm, driving a pair of Niigata ZP-41B Z-Peller propulsion units with AGCP192Y slipping built in clutch and 2.7m diameter FP propellers. Two identical diesel gensets of 136kWe each provide electrical power.

Accommodation is outfitted to MLC compliant standards for up to 10 personnel. The deck machinery comprises a MacGregor hydraulic anchor windlass/double drum escort towing winch, model MG-HAET/GDG-22-1223U02096x2, on the bow spooled with 200m line on each drum. A Mampaey disc-type towing hook is installed on the main deck aft.
