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: 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).

Abstract: A subsea structure for supporting pipes/pipe assemblies (2?) that are connected to subsea installations. The structure has a generally horizontal support member (5) for supporting said pipes/pipe assemblies. The horizontal support member is movably engaged with a generally vertical supporting member (2) at one or both ends thereof the vertical support member is anchored to a base member (3). In the vertical support member (2) a lifting mechanism with intermeshing ratchet dogs (32, 33) and elongate ratchets (12) is arranged, which is operated by a vertical screw (13).
