Abstract: A weak link arrangement (1) designed for location on an umbilical (6, 7) extending on the seabed between respective structures potentially subjected to environmental hazards, like being snapped by an iceberg, which umbilical includes communicating fluid pipes and electric cables, is described. The weak link arrangement (1) includes a seabed frame (2) supporting an umbilical having a weak link multiconnecting structure (3) (UTA) installed in line, which weak link multiconnecting structure (3) (UTA) ensures continuous communication through the fluid pipes and electric cables until emergency disconnection takes place. Such disconnection is initiated by accidental pull in the umbilical, which pull activates disconnecting means and cable severing means.

Abstract: An installation tool arrangement enables installation of a flexible elongated element, such as a conductor, cable, tube or tube bundle, into a pipeline and to extend the flexible elongated element from the surface of the sea to the seabed by the use of a per se known pipeline pigging technique. The tool arrangement includes a first pipe junction tool at the pipeline entrance end for the flexible elongated element, and a second pipe junction tool at the pipeline exit end for the flexible elongated element. The installation tool arrangement includes a leading pig connected to the flexible elongated element to have it advanced through the pipeline toward the seabed by advancing said pig by means of the fluid flowing in the pipeline.

Abstract: A subsea filler line system adapted to transport different types of fluids in separate batches through one single supply conduit, or flexible line, from the sea surface to respective dedicated storage tanks, or vessels, installed on the seabed, is described. The system includes respective valves and control systems to operate the subsea filler line system. The subsea filler line system includes at least two pigs adapted to be pushed by the transported fluid through said supply conduit, or flexible line, which pigs further provide a barrier between the respective fluids in front of and behind each pig, thus being able to define respective fluid batches between following pigs, each fluid batch being directed by means of valves through an inlet into said supply conduit and an outlet from said supply conduit and further on to the respective dedicated storage tanks, or vessels, on the seabed. A method for transporting various fluids in separate batches through a master flow conduit is also disclosed.

Abstract: 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.

Abstract: The invention relates to a manifold structure that includes a frame construction (1), a number of pipes (2), 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 (1) is designed with a number of support brackets (5) for respective coupling parts associated with said pipe terminations. Each support bracket (5) 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.

Abstract: Well template (11) for the protection of equipment for wells on the sea bed, comprising outer, upper template parts (17a, 17b) and flippable protection hatches (15) which, in a closed position, protect well slots. The protection hatches (15) are mounted so that they can flip up about two non-parallel flip axes.

Abstract: A connector means (10; 20) 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 (1; 1?) 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 (2; 2?) that retains a second end of the second pipeline (4) 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 (1; 1?).
