PROBLEM TO BE SOLVED: To provide a connection structure between a vessel and a loading arm capable of suppressing transfer of heat from an external part to an internal part without using a bayonet-fitting and capable of simply connecting a receiving pipe of the loading arm to a supply pipe of the vessel.SOLUTION: A connection structure between a vessel and a loading arm includes: a first double pipe 3 containing an inner pipe provided with a first inside flange on a tip thereof and an outer pipe 32 provided with a first outside flange 35; a second double pipe containing an inner pipe provided with a second inside flange on a tip thereof and an outer pipe provided with a second outside flange; a sleeve which is fastened to the first outside flange and the second outside flange 45, forms a closed space on a circumference of the first double pipe 4 and the second pipe between the first outside flange and the second outside flange, and is attached to the second double pipe so as to slide between a standby position on which the second inside flange is exposed and a connection position on which the fastening to the first outside flange and the second outside flange is performed; and a suction pipe path 7 which evacuates the closed space.SELECTED DRAWING: Figure 1

【課題】バイオネット継手を用いずに外部からの熱が内部に伝わることを抑制でき、かつ、船舶の供給管にローディングアームの受入管を簡単に接続することができるようにする。【解決手段】船舶とローディングアーム間の接続構造は、第１内側フランジが先端に設けられた内管および第１外側フランジ３５が設けられた外管３２を含む第１二重管３と、第２内側フランジが先端に設けられた内管および第２外側フランジが設けられた外管を含む第２二重管と、第１外側フランジおよび第２外側フランジ４５に締結されて、第１外側フランジと第２外側フランジとの間で第１二重管４および第２二重管の周囲に密閉空間を形成するスリーブ５であって、第２内側フランジを露出させる待機位置と第１外側フランジおよび第２外側フランジに締結される接続位置との間でスライドするように第２二重管に取り付けられたスリーブと、密閉空間を真空引きする吸引管路７と、を備える。【選択図】図１
