#NYK Line, Nihon Shipyard Co., Ltd. and IHI Corporation received an Approval in Principle (AiP) on December 26, 2022 from ClassNK for an ammonia floating storage and regasification barge (A-FSRB).
At this time, there are no international regulations for floating storage and regasification facilities when the cargo is #ammonia, and it is expected that the unique requirements of ammonia will have to be reflected in the design. Therefore, the parties and ClassNK conducted a comprehensive risk identification of various contingencies and worked to identify technical issues from the initial study stage. A risk identification was conducted using the gap analysis method, which identifies differences between conventional ships and offshore floating facilities (heavy oil, LNG, etc.) and evaluates the impact of such differences.
As a result, the parties extracted items for future technical studies of possible accidental incidents and differences between conventional ships and offshore floating facilities and obtained an AiP from ClassNK. This is the world's first acquisition of an AiP for an A-FSRB handling ammonia as cargo.
The parties will continue to study the arrangement and introduction of A-FSRBs with electric power companies, which are expected to be the main users of A-FSRBs, and to study legal compliance. Additionally, the parties will work on economic evaluation in parallel.

日本郵船株式会社、日本シップヤード株式会社、株式会社IHIの3社は、浮体式アンモニア貯蔵再ガス化設備搭載バージ (A-FSRB: Ammonia Floating Storage and Regasification Barge)について、2022年12月26日に一般財団法人日本海事協会から基本設計承認（AiP）を取得しました。
現時点において、貨物をアンモニアとした場合の浮体式貯蔵再ガス化設備に関する国際的に統一された条約や規則等は存在しないため、アンモニア特有の要件を設計へ反映することが求められると予想されます。そのため、３社と日本海事協会は、様々な偶発的事象に対する包括的なリスクを特定し、初期検討段階から技術課題の洗い出しに取り組みました。リスク特定に際しては、従来の船舶や浮体構造物(重油・LNG等)との差分を特定しその影響評価を行う手法(ギャップ分析法)を用いてリスクの特定を進めました。
その結果、想定される偶発的事故や従来の船舶や浮体構造物との差分に対する今後の技術検討項目を抽出し、日本海事協会からAiPを取得しました。アンモニアを貨物として取り扱うA-FSRBのAiPの取得は世界初となります。
今後も主なユーザーと想定される電力会社との配置・導入に関する検討や法規制対応の検討、および並行して経済性評価に取り組みます。
