RAmparts 2100-CL ASD Tug with 50T BP currently under construction and scheduled for delivery Q2 2022 

The vessel has been designed and built to Lloyds Class requirements with the following notation LR +100A1 Tug, *IWS, +LMC, UMS, Restricted Service.  The rule length has been kept under the 24 m Loadline and tonnage convention limits while optimizing for maximum hull volume, resulting in improved accommodation spaces and crew comfort.

 

The hull and skeg of the RAmparts 2100-CL have evolved to provide improved manoeuvring and side stepping capabilities. As with all RAmparts series vessels, the hull has been optimized for maximum thrust and bollard pull, while maintaining excellent manoeuvring and sea-keeping. A half-raised forecastle deck helps to keep the working deck safe and dry, while a gently rounded deck line in plan to ensure that the tug can safely and easily come alongside and remove itself from an attended ship at speed. Most importantly, the characteristic double chined stern unique to all Robert Allan Ltd. designs ensures that the tug can run astern at high speeds and maintain good control and directional stability.

 

The propulsion machinery to comprise of two Caterpillar 3512C(HD) marine diesel engines each rated 1500 kW at 1600 rpm, coupled to Schottel SRP 360FP azimuth rudder propellers to provide a bollard pull of 50 tonnes ahead and an expected bollard pull of 45 tonnes astern with the main engines developing 100% power.
