The invention relates to a marine pipelaying system comprising a vessel (1) provided with a pipeline launch tower (6). The tower (6) comprises pipe laying equipment defining a tower firing line, and is adapted for launching a pipeline (20) along the firing line into the sea. The system furthermore comprises a hang off module (15) supported in the lower part of the firing line for clamping and supporting the weight of previously launched pipeline (20) as well as a stinger for guiding the launched pipeline (20). The stinger (10) is supported at its upper end in the lower part of the firing line. The stinger is displaceable from the firing line.

摘要:
A dual firing line drilling installation has a drilling tower main structure with four frameworks that are each over a major portion of their height U-shaped in horizontal cross-section. A four-sided central (11) space is present, and along each side of the central space one framework is arranged with its opened vertical side facing the central space. First and second storage devices (25,27) are provided for vertically storing drilling tubulars. The first storage device is housed in a first framework, the second storage device in a second framework. A first hoisting device is supported by a third framework of the drilling tower main structure, to manipulate a string of drilling tubulars in a first firing line (21). A second hoisting device is supported by a fourth framework to manipulate a string of drilling tubulars in a second firing line (23). A first and second pipe racker (29,31) are housed within the drilling tower main structure and adapted to move drilling tubulars while supported in vertical orientation between a storage devices and a firing line.
