On 18 June, Mitsubishi Heavy Industries Group announced on its official website that Mitsubishi Shipbuilding, a subsidiary of the group, has received an order for two methanol dual-fuel-powered ro-ro vessels to be delivered to Toyotomi Marine Corporation and Fukushima Shipbuilding Corporation respectively. This is Japan's first order for methanol dual-fuel-powered ro-ro vessels, which will be built at Mitsubishi Shipbuilding's Shimonoseki Shipyard and Eura Plant and are scheduled for completion and delivery in 2027.
The new vessel has an overall length of approximately 169.9 metres, a beam of approximately 30.2 metres, a gross tonnage of 15,750, a speed of 21 knots, and a capacity to carry approximately 2,300 passenger cars; is equipped with a windshield in the bow and a vertical mast to reduce propulsive resistance; is equipped with a unique energy-saving system technology, which, in combination with high-efficiency propellers and a drag-reducing high-performance rudder, contributes to fuel efficiency; and is equipped with a high-performance dual-fuel main engine, which can simultaneously Using methanol fuel and heavy fuel oil, it can reduce CO2 emissions by more than 10 per cent compared to the same type of vessel using conventional fuel, reducing the impact on the environment.
In the future, through the use of green methanol, the new vessel can further reduce CO2 emissions, including emissions over its entire life cycle. In addition, the new vessels will help reform the way crews work by increasing cargo capacity and transport capacity per voyage as well as providing more space for vessel allocation plans compared to conventional vessels, thus providing more rest and holiday time.
Notably, while methanol dual-fuel powered ro-ro vessels are already in operation around the world, this is the first time a domestically produced methanol dual-fuel powered ro-ro vessel has been built in Japan.
Mitsubishi Heavy Industries says that against the backdrop of expanding demand for modal shifts in maritime transport, amidst a reduction in CO2 emissions from land transport, labour shortages and changes in work styles, Mitsubishi Shipbuilding will continue to work with its business partners to contribute to the stable operations of its customers through the construction of ferries and Ro-Ro vessels that are superior in terms of fuel efficiency and environmental performance.
