Abstract: A load transferring subsea structure (10) for temporary guiding and permanently relieve forces within a pipe connection that is subjected to bending moments when connection is completed. A connector (3) keeps the pipe ends (E1, E2) together. The load transferring structure (10) includes one basically stationary structure (1) that retains a first pipe end (E1) and one basically manoeuvrable structure (2) that retains the second pipe end (E2). The second pipe end (E2) is to be connected to the first, stationary pipe end (E1). The stationary structure (1) includes portions (6) having predetermined configuration including fitted surfaces (6a, 6b) for interaction during mating with complementary portions (11, 12) having predetermined configuration including fitted surfaces (14, 15) on the mobile structure (2) for creation of a load path external of the pipe ends (E1, E2).

Abstract: The invention is directed toward a T-pipe designed for transfer of high pressure fluids through the main run and where the branch run is left in a standby position for possible use in the future. The opening, or outlet, of the branch run is sealed by a material continuous with the main run. An opening and fluid flow in the branch run while the main run is in production and remains under full pressure, is to be provided. The sealing includes a metal membrane which is in contact with the fluid flowing in the main run. The metal membrane is thinner than the wall thickness of the T-pipe and is supported by a plug inserted in the branch run.

Abstract: An apparatus (10) for launching one or more pigs (5) for cleaning of production flow lines, or tubing, on the sea bed is shown. The apparatus includes a lifting frame (1) retaining a charging pipe (3) which is able to carry a train of pigs (51-510) resting stand-by in the charging pipe (3), a plurality of valves (V1-V4) which on the one side is in fluid communication with the charging pipe (3), and on the other side is in fluid communication with a high pressure drive fluid different from the production flow, a connecting means (2) for connecting of the apparatus (10) to a closable pipe sub leading to the production flow line to be pigged, and an actuatable piston (4) which is able to displace the train of pigs within the charging pipe (3).
