RMDC 8176 AHTS project is continuation of previous successful Project 1674. Facing increasing demands for deep water operations with eco-friendliness in mind we propose new cost-effective, powerful vessel with excellent capacities.
Its periodically unattended propulsion plant including main engines of 5400 kW each gives 170 tonnes bollard pull and 15 knots maximum cruising speed. Three tunnel thrusters provide good manoeuvrability and together with high-lift rudders enable position keeping with DP-2 class system fitted.
Vessel is fitted with 350 ton anchor handling / towing winch. 580 square meter working deck provides large space for 1000 tonnes of cargo or anchor handling operations.
With 3200 tonnes dead weight the vessel is ready to carry considerable amount of multiply cargoes in her tanks including fuel oil, liquid mud, brine, fresh water, dry bulk and drill water. Thanks to multi-function tanks the vessel can also carry over 1200 cubic meters of recovered oil.
