Abstract: The present invention relates to a marine pipelaying vessel for S-lay pipelaying an offshore pipeline and integrating one or more accessories into the pipeline, and a method for S-lay pipelaying wherein use is made of such a vessel. The vessel according to the invention comprises a hull (1) having a stinger end and a stinger (20) for guiding the launched pipeline in a curved pipeline trajectory, which stinger is pivotably connected to the hull, and an accessory handling J-lay tower (30) at the stinger end of the hull. The J-lay tower allows the pipeline and connected accessory to be laid in J-lay mode while connecting further pipe sections to the pipeline at least until the accessory has been lowered past below the retracted stinger. A stinger support assembly (15) is provided for supporting the stinger in a pipelay position, and for allowing movement of the stinger between the pipelay position and a steep downwardly pivoted retracted position by pivoting the stinger about its stinger pivot axis, wherein the stinger in the retracted position is away from the J-lay firing line.

Abstract translation: 本发明涉及一种用于S型铺设海上管道并将一个或多个附件集成到管道中的船用管道铺设船，以及一种用于S型铺设管道铺设的方法，其中使用这种船只。 根据本发明的容器包括具有刺血针端的船体（1）和用于以弯曲的管道轨迹引导所发射的管道的托管架（20），该托管架可枢转地连接到船体，以及处理J型塔架 （30）在船体的刺痛末端。 J型塔允许管道和连接的附件以J形铺设模式放置，同时将进一步的管道连接到管道，至少直到附件已经降低到缩回的托管架以下。 提供了一种支架组件（15），用于将托管架支撑在管道铺设位置，并且用于通过围绕其托管架枢转轴线枢转托管架来允许托管架托架在托管位置和陡峭的向下枢转的缩回位置之间的移动，其中托管架 缩回位置远离J-lay发射线。
