New RAmparts 3200-SD Tug for the Royal Thai Navy

June 22, 2021

Robert Allan Ltd. is very pleased to announce the signing of a contract with Asian Marine Services Public Company Limited (ASIMAR) of Thailand for the design of a RAmparts 3200-SD tugboat for the Royal Thai Navy. ASIMAR signed the construction contract with the Royal Thai Navy on May 25th, 2021, with Admiral Chatchai Sriworakan, Commander in Chief presiding over the signing ceremony.

The RAmparts series of tugs are a well-proven, highly successful series of Z-drive tug designs with more than 180 RAmparts 3200 tugs having been built to date. Incorporated into this design are all the features that have distinguished the RAmparts 3200 tug designs including high speed, excellent stability and sea keeping, enhanced astern performance and manoeuvrability that enable the tugboats to successfully fulfill push and tow missions. The Royal Thai Navy currently operates two RAmparts 3200 tugs, and this third RAmparts 3200 tugboat will, similar to the previous two tugs, have approximately 55 Tons Bollard Pull and a speed of over 12 knots.

This tugboat will support fire-fighting missions with a 2,400 m3/hr Fi-Fi pump with fire monitors capable of 120 meters throw distance and oil spill recovery missions can be accomplished with DESMI oil spill response solutions and environmental friendly – biological formular oil dispersant bioQ.

This cooperation between Robert Allan Ltd. and ASIMAR will open additional opportunities in the future for the Thai shipbuilding industry to learn and develop new knowledge in ship design and construction.
