Abstract: A slew bearing includes a stationary bearing ring to be fixed to a base, and a moveable bearing ring to be fixed to a moveable object, wherein the stationary bearing ring and the moveable bearing ring are configured to enable rotation of the moveable bearing ring relative to the stationary bearing ring about a rotation axis. A main axial bearing and an auxiliary bearing are provided between the stationary bearing ring and the moveable bearing ring, wherein the moveable bearing ring includes one or more main portions and one or more auxiliary portions, which one or more main portions are moveable relative to the one or more auxiliary portions between an operational position, in which the main axial bearing transfers the axial loads between moveable bearing ring and stationary bearing ring, and a raised maintenance position, in which the auxiliary axial bearing transfers the axial loads between moveable bearing ring and stationary bearing ring and the main bearing is allowed to be inspected and/or maintained so that the slew bearing during inspection and/or maintenance is still operational.

Abstract: A method for reel-laying pipelines from a vessel includes reel laying a first pipeline by unwinding a first reel, and guiding the pipeline via a guide wheel through a tensioners and a hang off clamp into the sea; closing the hang off clamp to support the first pipeline; connecting an end portion of the first pipeline to a retaining system; replacing the first reel by a second reel; providing a temporary connection between an end portion of the second pipeline and the end portion of the first pipeline; disconnecting the first pipeline from the retaining system; opening the hang off clamp; continuing reel laying by unwinding the second reel; closing the hang off clamp; removing the temporary connection between the first and second pipeline; and connecting the first and second pipeline end to end between the tensioners and the hang off clamp.
Abstract translation: 一种用于从容器卷取管道的方法包括：通过展开第一卷轴来放置第一管道的卷轴，以及经由导轮将管道通过张紧器和悬挂夹具引导到海中; 关闭吊卡以支撑第一条管道; 将第一管道的端部连接到保持系统; 用第二卷轴代替第一卷轴; 在第二管道的端部和第一管道的端部之间提供临时连接; 将第一管道与保持系统断开连接; 打开吊卡; 通过展开第二卷轴继续卷轴; 关闭吊卡; 去除第一和第二管道之间的临时连接; 并且将第一和第二管道端部连接到张紧器和悬挂夹具之间。

Abstract: A marine pipelaying friction clamp device for frictionally retaining an offshore subsea pipeline to be launched into the sea includes a frame which includes a main frame structure that is adapted to be supported by the pipelaying vessel. The frame supports multiple annular arrays of clamping units adapted to simultaneously engage separate portions of the pipeline. The frame further includes one or more mobile subframes for one or more of said annular arrays of clamping units. Each of said one or more mobile subframes is movably supported by the main frame structure so as to be mobile relative to said main frame structure in said longitudinal direction of the clamp device, and each of said one or more mobile subframes is supported by a spring assembly.
