RAmparts 3000 takes shape
May 10, 2007
The first hull in a series of Cheoy Lee RAmparts 3000 ASD tugs (yard #4908) emerged from the steel fabrication hall recently. Like the slightly shorter, but beamier Cheoy Lee Z-tech model, the RAmparts 3000 originates from the design office of Canadian naval architect Robert Allan. Like Cheoy Lee, Robert Allan is a business that has remained in the same family for successive generations, and the relationship between the two parties is proving a tremendous success. Robert Allan established a naval architectural consulting firm in Vancouver in 1930, shortly before Cheoy Lee moved operations from Shanghai to Hong Kong, in 1936.
Yard #4908 is the first in a batch of six of these 30m long, 55 ton bollard pull all steel tugs. All are destined for large mining operations in Australia, the first two being fitted with twin continuously rated Caterpillar 3516B diesel engines, each developing 2,260hp, with the subsequent four vessels being fitted with larger Niigata units. Cheoy Lee’s huge demand for engines now means that several different suppliers are needed to satisfy the shipyards requirements.
The tugs can carry a complement of eight, and, propelled by twin azimuthing Rolls Royce Z-drive propulsion units, have a free running speed in excess of 12.5 knots. Fuel capacity is 78,000 litres (20,600USG), and water 26,000 litres (6,870USG).
Such is the demand for Cheoy Lee’s commercial vessels, and high level of production efficiency, yard #4908 is scheduled to be completed in August.
