PSA Marine of Singapore, one of the largest harbour tug owners and operators in Asia, took delivery of two RAmparts 3200 class tugs from Cheoy Lee Shipyards, Hong Kong and Yuexin Ocean Engineering Co. Ltd., Guangzhou, PR China respectively.
The RAmparts Class tugs, Rubicon and Righteous, from the design portfolio of Robert Allan Ltd., Naval Architects of Vancouver BC are a series of now exceptionally well-proven ASD tug designs.
Each of these designs has been developed from a successful prototype vessel or series of vessels, and refined to emphasize ease of construction. Each new delivery is also custom-tailored to the needs of each individual client.
Robert Allan Ltd. worked closely with Cheoy Lee Shipyards and Yuexin Ocean Engineering Co. Ltd in the design development of these two tugs which are specialized for ship-assist service and coastal towing.
Although carrying the same RAmparts 3200 designation, Rubicon, a RAmparts 3200CL design, was uniquely designed for Cheoy Lee Shipyards to suit their production facilities and Client base. The most notable feature of this design is the shallower draft than the standard tug, a frequent requirement in Asia. The Righteous is a RAmparts 3200W design with slightly different characteristics.
On trials, Rubicon and Righteous both exceeded all performance expectations with bollard pulls greater than 65 tonnes and a speed of 12.8 knots.
