Mitsui O.S.K. Lines, Ltd. (MOL) announced the successful naming and launch ceremony of the LNG-fueled ferry Sunflower Pirka on September 4th, 2024, at the Naikai Zosen Corporation shipyard. The launch was supported by the LNG-fueled tugboat Ishin, operated by MOL Group’s Nihon Tug-Boat Co., Ltd., marking another milestone in MOL's ongoing efforts to promote low-carbon shipping solutions.
Sunflower Pirka joins MOL's growing fleet of LNG-powered vessels, which includes Sunflower Kurenai and Sunflower Murasaki, both operational on the Osaka-Beppu route since 2023, and the upcoming Sunflower Kamuy, slated to enter service on the Oarai-Tomakomai route in early 2025. With these additions, MOL Group will operate four LNG-fueled ferries across Japan’s East-West routes, further solidifying its position as the operator of the country’s largest LNG-powered ferry fleet. In total, MOL Sunflower operates 10 ferries and 5 RORO vessels on 6 routes, providing comprehensive logistics and passenger services.
The new ferry is designed to reduce CO2 emissions by ~35% compared to current vessels on the Hokkaido route. This reduction is achieved through the use of LNG fuel and advanced technologies such as the Ishin hull form, which harnesses oblique headwinds for propulsion, along with other energy-saving devices developed by Naikai Zosen. The ship will also be fitted with high-performance engines optimized for LNG fuel use.
In addition to its environmental benefits, Sunflower Pirka addresses Japan's "2024 logistics problem" by providing expanded truck capacity and improved accommodations for drivers, with private cabins enhancing comfort during long voyages. This aligns with Japan's Modal Shift initiative, which aims to reduce road congestion and promote more efficient freight transport.
MOL’s commitment to LNG-fueled vessels is built on the expertise gained through pioneering projects like the Ishin tugboat, which was delivered in 2019 as one of the first LNG-fueled tugs in operation. The development and operation of Ishin have played a crucial role in advancing MOL’s LNG-powered fleet, with the knowledge gained applied to the Sunflower Pirka and other upcoming LNG vessels.
