Ship-to-Ship Bunkering Boom for Fuel Ammonia
world's first to Obtains AiP from ClassNK
On 31 July, TB Global Technologies (TBG), a group company of Tokyo Boeki Holdings Corporation,
and Nippon Yusen Kabushiki Kaisha (NYK) received the world's first Approval in Principle (AiP) fromClassNK for the bunkering boom, a device for the Ship-to-Ship supply ofammonia fuel, which had

been jointly developed by the two companies.
* As of 31 July 2024

AiP certificate issued by ClassNK◼

TBG's innovative bunkering Boom for Fuel Ammonia.
The Emergency Release System (ERS) developed by TBG takes full account of the toxicity ofammonia and ensures safety. The bunkering boom for ammonia fuels* equipped with this device
was the first bunkering boom in the world to receive an AiP from ClassNK, following a drawing
review and a certification process for new technologies that partly refers to Guidelines for Technical
Qualification. The new bunkering boom significantly reduces the amount of ammonia spatter. Itensures the safety of the surrounding area when an Ammonia Bunkering Vessel** (ABV) and anAmmonia Fuel Vessel (AFV) are separated in an emergency.

NYK provided TBG with design data for in-house developed ABV, on which it designed thisbunkering boom. In addition, a multifaceted risk assessment, including advice on safety andoperations based on NYK's expertise in operating LNG bunkering vessels (LBV) and ammonia
handling, resulted in the technical feasibility being assessed by ClassNK, leading to the acquisitionof an AiP.

Prospects
The bunkering boom for ammonia fuels, for which the AiP was awarded this time, will be installedon ABV, which are expected to become popular from the late 2020s TBG will continue to develop
safe and environmentally friendly products and contribute to the realization of a decarbonizedsociety.

Decarbonization of marine fuels is an unavoidable social challenge.
The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) states that ” As one of theworld's leading shipping and shipbuilding nations, it is important for Japan to take the lead indeveloping and promoting international measures to reduce GHG emissions to actively contributeto international efforts to combat global warming while ensuring the sustainable development ofmaritime trade and the maritime industry”,* and the International Maritime Organization (IMO) has
set a target of ” zero GHG emissions from international shipping by 2050”**. In this global context,
ammonia is attracting attention as a next-generation marine fuel with low environmental impact.
Ammonia is a clean fuel that does not emit CO2, but it is toxic, so safety measures are important .
