    摘要： An aspect of the present invention relates to an underwater electrical connection arrangement (3) for a floating offshore structure (100), in particular for a floating wind turbine (1), comprising at least one electrical cable (32) and a water tight cladding tube (31) in that the electrical cable (32) is received, so that a cavity (33) remains inside the cladding tube (31). The cladding tube (31) is designated to be fixed to the floating offshore structure (100) and to follow a trajectory from the floating offshore structure (100) towards a seabed (5). The cladding tube (31) is designated to be at least partially immersed in water, in particular sea water, in an intended state of use of the underwater electrical connection arrangement (3). The cavity (33) is at least partly filled with a first medium (34) having a lower density than the water, in particular sea water, in that the cladding tube (31) is immersed in the intended state of use, so that, in the intended state of use, an at least local uplift force is created.
    The underwater electrical connection arrangement is more robust, cheaper and easier to install than current underwater electrical connection arrangements.

    摘要： A connector assembly (30) for use in subsea environments comprises a plug (32) and a receptacle (34) generally arranged about a longitudinal axis (36). The plug (32) comprises a plug body (38) through which a down hole gauge cable (40) extends. The receptacle (34) comprises a receptacle body (42) and through which a supply cable (44) extends for connection with the down hole gauge cable (40). The plug (32) and the receptacle (34) are secured together via a securing nut (48). The plug (32) and the receptacle (34) are in contact and form a primary seal (70). A rotary test adaptor (46) is located radially outwardly of and is sealed against an outer surface (110) of the plug body (38) and is located radially inwardly of and is sealed against a radially inner surface (108) of the securing nut (48). The rotary test adaptor (46) comprises an outer surface (51) and an inner surface (116) and a test port (50), the test port (50) extends through the rotary test adaptor (46) from the outer surface (51) to the inner surface (116) and is in fluid communication with the primary seal (70).

    摘要： An offshore arrangement (8), in particular offshore wind farm, with at least one floating installation (9, 10), the at least one floating installation (9) comprising:
    a floating foundation (11),
    at least one mooring line (14) for mooring the floating foundation (11) to the seabed (13), and
    at least one energy cable (16) for transmitting energy to or from the at least one floating installation (9) to or from another offshore and/or onshore installation (10), the at least one energy cable (16) being attached to the at least one mooring line (14).
    By attaching the at least one energy cable to the at least one mooring line, the at least one energy cable hanging from the foundation to the seabed is better protected from loads caused by the dynamic offshore environment.
