Mitsubishi Heavy Industries (MHI) has announced that it has received an order, jointly with Imabari Shipbuilding, for two next-generation pure car and truck carriers (PCTCs) for Nippon Yusen Kabushiki Kaisha (NYK Line).

Each ship will be 200m long, 35m wide and 38m draught, with capacity for about 7,000 vehicles. The larger ship size is being adopted in anticipation of the planned expansion of the Panama Canal. They will adopt a number of MHI’s energy-saving technologies, notably the Mitsubishi Air Lubrication System (MALS), along with electronically controlled Mitsubishi-UE main engines, the Mitsubishi Hybrid Turbocharger, a windscreen at the ship's bow to reduce wind resistance, and a Mitsubishi Energy Saving Hybrid Inverter Pump (MESHIP), an inverter-controlled cooling seawater pump that enables optimised pump operation.

MALS is MHI's proprietary technology that reduces frictional resistance between the ship hull and seawater by introducing a layer of air bubbles blown from the ship's bottom. The Mitsubishi Hybrid Turbocharger is a generator-integrated MET engine exhaust gas turbocharger that uses waste heat to generate electric power while at sea. These measures are expected to achieve a saving in fuel consumption of over 30% per vehicle carried compared with existing ships.

MHI will provide Imabari with design information on incorporating its advanced ship technologies in the PCTC design, while Imabari says it will contribute significantly through its strong cost competitiveness. Based on MHI's design concept and technologies related to energy saving, Imabari will undertake the detail design and actual construction. MHI will supply core components, including the main engines and propellers. The two ships are scheduled for completion in 2015.

The new order builds on the existing working relationship between MHI and Imabari, which earlier this year formally agreed to collaborate on technology relating to container ships, another onitiative aiming to effectively integrate MHI's design capabilities and Imabari's shipbuilding capacity and cost competitiveness. MHI has additionally agreed to license the manufacture and marketing of its deck machinery to Imabari.

MHI’s long-term strategy is to focus on high value-added vessels, such as cruise ships and next-generation LNG carriers, and to strengthen its engineering operations by providing proprietary technologies to other companies both in Japan and overseas.
