    • The invention concerns a method for installing a hatch (34) to a subsea structure (10) by connecting the hatch to the subsea structure by at least one hinge (20) having a first mounting portion (21), a second mounting portion (22), a flexible portion (23) interconnecting the first and second mounting portion allowing a pivot connection between the first and second mounting portion. The installation steps comprise • - inserting a protrusion (23) of the first mounting portion (21) into an installation hole arranged in the subsea structure (10), • -inserting a protrusion (24) of the second mounting portion (22) into an installation hole arranged in the hatch (34), thereby • -engaging the first mounting portion (21) of the hinge (20) for anchorage with the subsea structure (10) and engaging the second mounting portion (22) for anchorage with the hatch (34) thereby arranging for the hatch to pivot between a closed and an open position about a pivot axis provided by the flexible portion of the hinge. The invention also concerns a hinge and an assembly for subsea use.
    • 本发明涉及一种通过至少一个具有第一安装部分(21)的铰链(20)将舱口盖连接到海底结构来将舱口(34)安装到海底结构(10) ),第二安装部分(22),互连第一和第二安装部分的柔性部分(23),从而允许第一和第二安装部分之间的枢转连接。 安装步骤包括: - 将第一安装部分(21)的突起(23)插入布置在海底结构(10)中的安装孔中, - 将第二安装部分(22)的突起(24) 设置在舱口(34)中的安装孔,从而·将铰链(20)的第一安装部分(21)与用于锚固的水下结构(10)接合并且将用于锚固的第二安装部分(22) 由此将舱门设置成围绕由铰链的柔性部分提供的枢转轴线在闭合位置和打开位置之间枢转。 本发明还涉及用于海底使用的铰链和组件。
