Wärtsilä propulsion for six new container-ships

Wärtsilä has been awarded the contract to supply the engines and propulsion equipment for six new Ro-Ro container vessels being built for the National Shipping Company of Saudi Arabia (NSCSA).

The ships are being built at the MIPO shipyard in South Korea, and when launched will be operated by Mideast Ship Management Ltd, a subsidiary company of NSCSA. Each of the six ships will feature Wärtsilä RT-Flex 58TD engines, controllable pitch (CP) propellers, and the Wärtsilä Energopac system. Delivery of the equipment for the first vessel is scheduled for May 2012, and the vessels are slated for delivery from the shipyard in 2013 and 2014.

The package combines the latest common rail fuel injection and valve actuation engine technology, featuring integrated electronic control. Wärtsilä's flexible engine settings enable lower minimum running speeds, which together with the aforementioned features, offer reduced fuel consumption, lower emissions and longer intervals between overhauls. Fuel consumption will be further reduced by integrating the propeller and rudder design into a single unit with the installation of Wärtsilä's Energopac system. The Energopac system is designed specifically for each individual vessel, and can be optimised to achieve the maximum possible fuel savings without compromising manoeuvrability or comfort levels.

The RT-Flex engines provide smokeless operation at all speeds, and the propulsion package will enable these vessels to comply with the requirements of the IMOs Tier II regulations.
