Japan's Imabari Shipbuilding is building two LNG-fuelled bulk carriers, with commissioning expected in 2025.
Imabari has placed two additional orders with fellow Japanese firm Mitsubishi Shipbuilding for a fuel gas supply system (FGSS) and LNG fuel tanks for the bulk carriers. Commercial operations of the bulk carriers are expected in mid-2025, although further details such as potential term charters and construction prices are unknown.
Mitsubishi Shipbuilding said its FGSS is able to reduce 99pc of sulphur oxide and 86pc of nitrogen oxide compared with conventional carriers using fuel oil. The technology also increases energy efficiency by 40pc that reduce carbon dioxide (CO2) emissions during transportation.
Japanese shipping firms are accelerating their switch to LNG-fuelled vessels from conventional fuel oil, aiming to achieve carbon neutrality.
Japanese engineering firm and shipbuilder Hitachi Zosen is the latest to pursue the technology, carrying out trials during May of a marine fuel engine using "carbon-neutral" LNG using carbon credits obtained from supporting environmental programmes. The process aims to offset CO2 emissions from all production and transportation. Carbon neutral LNG can reduce 98pc of CO2 emissions compared with using fuel oil, Hitachi Zosen said.
Hitachi Zosen, together with Japanese shipping firm Mitsui OSK Line and engineering firm Yanmar Power Technology, are already working on developing technology to reduce methane emissions from LNG-fuelled ships through catalyst and engine improvements. Japan's state-owned research institute Nedo has backed the project for six years to March 2027.
