The environmental sustainability and reduced operating costs of Wärtsilä's integrated propulsion solution were major factors in the winning of these orders. Wärtsilä has been awarded the contract to supply the engines and propulsion equipment for six new Ro-Ro container vessels being built for NSCSA, the National Shipping Company 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.
