Wärtsilä is to supply the engines and propulsion equipment for the six new RoCon vessels on order for NSCSA, the National Shipping Company of Saudi Arabia, at Korea's Hyundai Mipo Dockyard (see earlier story).
On delivery, the vessels will replace NSCSA's current RoRo ships that are operating as a liner service between the U.S East Coast to the Middle East (Red Sea-Arabian Gulf) and to the Indian Sub-Continent (ISC) via Europe. They will be operated by Mideast Ship Management Ltd, a subsidiary company of NSCSA.
The scope of the integrated solution 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, 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 along with the other 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 optimized to achieve the maximum possible fuel savings without compromising maneuverability or comfort levels.
"We are delighted to have been awarded this important contract for these new Ro-Ro container vessels. It is an important segment for Wärtsilä, and NSCSA is one of the biggest shipping conglomerates in the world. The environmental sustainability and reduced operating costs of the integrated Wärtsilä propulsion solution were major factors in Wärtsilä winning this order," says Ibrahim Behairy, Director, Merchant Sales, Wärtsilä Ship Power.
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 offer optimum power output and shaft speeds with an extremely high degree of reliability. They can be operated for as long as three years between overhauls, and provide economical fuel consumption across the entire operating range. The engines are capable of extremely low and stable running speeds, which makes them highly applicable for container vessels that are often operated at 'slow steaming' speeds to save fuel.
