米海軍病院船の交代　Hospital Ship Replacement

概説

Center for Innovation in Ship Design Technical Report Hospital Ship Replacement The Center for Innovation in Ship Design (CISD) requested the development of a concept that could serve as a replacement for the existing hospital ships. The U.S. Navy plays a significant role in humanitarian missions by providing immediate aid during disaster situations. The existing hospital ships, USNS Mercy (T-AHS 19) and USNS Comfort (T-AHS 20) carry out two missions: 1) to provide medical and surgical care in support of U.S. amphibious task forces, and 2) to serve as a full-service hospital for use by various government agencies involved in support of non-combat roles such as disaster relief and humanitarian assistance. These hospital ships are over 35 years old and will need to be replaced once they are at the end of their service life. Other shortcomings include excessive draft, seakeeping at zero knots, low-speed maneuverability and inadequate patient throughput. The Navy Bureau of Medicine has stressed the need for modular medical facilities and amphibious support to enable increased ship-to-shore patient transfer and extend medical capabilities ashore. 船舶設計テクニカルレポート 病院船の交代におけるイノベーション 船舶設計のイノベーションセンター（CISD）は、既存の病院船の代替となりうる概念の開発を要請した。米海軍は、災害状況の間に直接の援助を提供することで、人道支援において重要な役割を果たしています。既存の病院船、USNSマーシー（T-AHS19）とUSNS Comfortは（T-AHS20）2つのミッション遂行する：1）米国の水陸両用のタスクフォースを支援するために医療や外科的なケアを提供するために、2）として機能するようにこのような災害救援や人道支援などの非戦闘の役割の支援に関わる様々な政府機関が使用するためのフルサービスの病院。これらの病院船は、船齢35年以上であり、寿命の終わりになったら交換する必要があります。他の問題点は、過度のドラフト、ゼロノットで耐航性、低速機動性と不十分な患者のスループットが含まれています。医学の海軍局はモジュラー医療施設と増加した船から陸への患者の転送を有効にして岸に医療機能を拡張する水陸両用支援の必要性を強調している。 NSWCCD-CISD–2011/004
