Abstract: The present invention concerns a cooling apparatus for subsea applications with a shell and tube heat exchanger. The heat exchanger includes a longitudinal shell. The shell forms a cavity with a fluid inlet port and fluid outlet port. A bundle of tubes extends from an inlet plenum chamber with an inlet port and into the shell on the same side of the shell as a bundle of tubes extending from an outlet plenum chamber with an outlet port. At least one tube sheet seals against the shell cavity and the inlet and outlet plenum chambers. The bundle of tubes extending from the inlet plenum chamber is in fluid connection with the bundle of tubes extending from the outlet plenum chamber. A retrievable pump module with a sealed pump module housing is placed adjacent the heat exchanger and includes a motor driving an ambient sea water pump.
Abstract: An apparatus for feeding an elongate article (6) from a floating vessel and suspending a first portion (6a) of the elongate article in a body of water below the vessel, comprises a cylindrical body (10) rotatably supported on the vessel and driving means (85, 86) for controlling the rotation of the cylindrical body. The cylindrical body (10) further comprises a spooling-on region (P) and a spooling-off region (U) for the elongate article, and a cylindrical contacting surface (18) for interaction with at least a portion of the elongate article (6); the contacting surface (18) being configured so as to support the first portion (6a).

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).
