Japan’s First LNG-Powered Cruise Ship Begins Operations with Shore Power Capabilities

NYK Cruises has officially christened its newly constructed cruise vessel, Asuka III, marking a notable moment in Japan’s maritime sector. The 52,265 gross ton ship, considered the first passenger cruise vessel built under the Japanese flag in 34 years, was named on July 11 at the Osanbashi International Passenger Terminal in Yokohama.

Just three days after the ceremony, the vessel completed its first bunkering operation with liquefied natural gas (LNG) at the Chuo Wharf in Hakata Port. The refueling was carried out by KEYS Azalea, Japan’s first dual-fuel LNG bunkering vessel, operated by Fukuoka-based KEYS Bunkering West Japan Ltd. This event also marked the first time KEYS Azalea has bunkered a cruise ship, having previously served primarily car carriers and bulk carriers transporting iron ore and coal.

Asuka III is scheduled to embark on its maiden voyage on July 20. Once in operation, it will join the 50,444 GT Asuka II, making it the first time NYK Cruises will operate two cruise ships simultaneously. According to the company, Asuka III is set to call at 30 domestic ports across Japan, excluding Yokohama.

The vessel is powered by LNG, which is expected to significantly reduce greenhouse gas emissions along with sulfur oxides and nitrogen oxides. Its dual-fuel capability also allows it to operate on marine gas oil and, if required, heavy fuel oil.

In terms of technological features, Asuka III stands out as the first Japanese-flagged cruise ship to incorporate both dynamic positioning and pod propulsion systems. Additionally, the vessel has been outfitted with an alternative maritime power system, enabling it to connect to shore-based electricity while docked. This system, also known as shore power or cold ironing, allows the ship to shut down its engines in port, thereby reducing overall emissions and environmental impact.
