The first two boats, named Chincha and Tupac, are now under construction at the Wuxi Shipyard in China, for SAAM's Peruvian affiliate Tramarsa, with others soon to follow.
In addition to the design, Robert Allan Ltd. also provided a complete structural steel parts package developed from the design drawings prepared for this project. Parts were defined and nested using ShipConstructor software, complete with part identification code, suitable as input to the shipbuilder's NC burning code.
The 24.4 m long x 11.25 m beam RAmparts 2400-W Class tugboat is a twin Z-drive, diesel-powered tug, designed for maximum efficiency in the performance of ship-assist and terminal support operations.

The tugs will also provide firefighting capability and have up to date accommodations for a crew of six in two single and two double cabins.
