A tool for lowering, alternatively later retrieval, of a pipeline end which is provided with a connecting part designed for mating with and connection to a first connecting part on the seabed is shown. The tool is so arranged that the tool can be brought to the surface again for reuse. The tool comprises a central lifting frame, a guiding part forming an extension of the lifting frame and a lifting yoke, which tool includes gripping mechanisms which, in one situation, are actuatable to partly circumscribe and retain the pipeline end, and, in a second situation, the gripping mechanisms are releasable to release the pipeline end from the lifting frame.

Tool for a horizontal connecting device

The invention relates to a manifold structure that includes a frame construction (), a number of pipes (), a pipe bend and possible valves, deployed in a pipe system having a number of pipe terminations projecting from the frame construction. The frame construction () is designed with a number of support brackets () for respective coupling parts associated with said pipe terminations. Each support bracket () is made as a separate, standardized unit that includes several securing means for releasable assembly to the frame construction, where each securing means is arranged for defined adjustability in height and lateral direction for adaption to a preinstalled pipe termination.

Manifold structure having adjustable brackets

A connector means () for tie-in and connecting of a first pipeline and a second pipeline on the seabed is shown. The connector means comprises a first connector part () retaining a first end of the first pipeline. The first connector part and the first pipeline are designed to be lowered and deployed on the seabed in advance of the connecting operation. A submersible second connector part () that retains a second end of the second pipeline () is also included. The second connector part and the second pipeline are designed to be lowered from the surface of the water toward the first connector part (). The connector parts () comprises means () that cooperate during relative motion between said connector parts, and is hinged tilting the second connector part () by means of forced motion, and thus aligning the second pipe end () in the direction toward the first pipe end () such that the first and second pipelines are brought to be in line with each other on the seabed. In addition a connector () is arranged between the connector parts for final connection between the pipeline ends.
