Wärtsilä Outfitting Six Ro-Ro Vessels

Posted on November 1, 2011

Wärtsilä has received a contract to supply the engines and propulsion equipment for six new Ro-Ro container vessels being built for NSCSA, the National Shipping Co. of Saudi Arabia.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.

The scope of the package for each of the six ships includes Wärtsilä RT-Flex 58TD engines, controllable pitch (CP) propellers and the Wärtsilä Energopac system. The orders for these various items have been booked on an incremental basis, the last one being the Energopac order, which was signed in September. Delivery of the equipment for the first vessel is scheduled for May 2012, with the vessels slated for delivery from the shipyard in 2013 and 2014, Wärtsilä said.

The package combines common rail fuel injection and valve actuation engine technology, featuring integrated electronic control. 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.

The Wärtsilä RT-Flex engines can be operated for three years between overhauls, and provide economical fuel consumption across the entire operating range, Wärtsilä said. Fuel consumption can be further reduced by integrating the propeller and rudder design into a single unit with the installation of Wärtsilä’s Energopac system, according to the company.
