Expansion of the RAmparts 3200-CL Fleet

The RAmparts 3200-CL was developed by Robert Allan Ltd. exclusively for Cheoy Lee Shipyards, Hong Kong. Since the first tug of this design was delivered in 2011, Cheoy Lee has delivered over 20 units of this series to its clients around the world.

In July, Cheoy Lee was extremely busy with the delivery four more RAmparts 3200-CL tugs to their owners: three of them, Hawksbill, Flatback and Loggerhead for Loreto Maritime Pte. Ltd, Singapore and one, Limin ASD 55, for Limin Marine & Offshore Pte. Ltd., Indonesia. These tugs will be operated in Australia and Indonesia respectively.

The vessels are outfitted to the highest standards for a normal operating crew of up to 10 people. The Master and Chief Engineer cabins are located on the main deck with four double crew cabins located in the lower accommodations.

The deck machinery comprises a ship assist hawser winch on the bow, and one towing winch on aft deck. In addition, a knuckle boom deck crane is installed on aft deck for handling of service parts and small cargo.

Main propulsion for each tug comprises a pair of CAT 3516C diesel engines, each rated at 2682 BHP at 1600 rpm, and each driving a Schottel, SPR 1515 fixed pitch Z-drive unit, in ASD configuration. The electrical plant comprises two (2) identical diesel gen-sets, each with a power output of 2 x 112 ekW.

Fire-fighting monitors are located at the top of wheelhouse, providing ‘off-ship’ fire-fighting service that meets Class Fire Fighting Ship 1 requirement.

Ship-handling fenders at the bow consist of two rows of 800 x 400 cylindrical fenders at the main deck lever, with a 480x300 mm “W” block fender below. A 300 x 300 hollow “D” fender provides protection at the main deck sheer line and along the knuckle, and 500x450 mm “W” block type fendering is used at the stern.
