Daniel K. Inouye LNG Installation Nearing Completion

The last of Daniel K. Inouye’s (DKI) three liquified natural gas (LNG) fuel tanks were installed in March. The remainder of the work, including associated piping and other conversion equipment, is expected to be completed by the first week of June. The overall cost of the conversion is estimated at $35 million and will reduce DKI’s CO2 emissions by 24%.

Built in 2018, when commercial supplies of LNG were not yet available in our network, DKI, its sister ships Kaimana Hila (2019), Lurline (2019), and Matsonia (2020) were all outfitted with LNG-capable dual-fuel engines in anticipation of their eventual conversion.

Following the DKI conversion,Matson also plans to replace the main engine on Manukai with a dual-fuel engine. Kaimana Hila is expected to convert to LNG in 2Q24, with an estimated five-month completion time and a cost of $35 million.

“As a company that cares deeply about the environment, Matson is committed to reducing its carbon footprint through numerous short and long-term goals, including a 40% reduction in CO2 emissions by 2030 and net-zero CO2 emissions by 2050,” said Matt Cox, chairman and chief executive officer. “Conversion to LNG is a big step toward achieving these goals.”
