A subsea screen connection assembly configured to electrically couple a subsea cable having an earth screen, the earth screen at least partially surrounding a cable core, to a subsea device. The subsea connection assembly has a connector body configured to be electrically connected to the subsea device and a clamping element configured to at least partially surround the earth screen of the subsea cable in a circumferential direction and to apply a clamping force in a radial direction to the at least partially surrounded earth screen of the subsea cable, the inner diameter of the clamping element being adjustable, and the clamping element configured to electrically connect the earth screen to the connector body.

High capacity (10 GW, for example) passively cooled non-superconducting underground high voltage direct current electric power transmission lines (100) of very low loss (1% per 1,000 km, for example) and competitive cost. The transmission lines (100) include segment modules (101) linked together with compliant splice modules (102) between the segments (101), typically installed in a protective conduit (103). The segment modules (101) include relatively rigid pipe-shaped conductors (117) insulated by pipe-like solid insulating layers (131) to form segment modules (101) that resemble pipe. The segment modules (101) are linked together through radially and axially compliant splice modules (102) to form the transmission line (100). There are preferably wheels (300) deployed to ease insertion and removal of the assembled segment modules (101) and splice modules (102) into the conduit (103), to center each segment module (101) within the conduit (103), and/or to provide motive force and/or braking to allow the assembled segment modules (101) and splice modules (102) to be installed on a slope.

An outdoor mounting assembly for use with an electrical device such as an outlet. A post has a hollow body with an upper end and a lower end. A receptacle housing is removably connected to the upper end of the post. The receptacle housing has a top and a plurality of side walls defining an interior cavity. At least one of the side walls has an opening providing access to the interior cavity. A cover is moveably connected to the receptacle housing. The cover has an opening to permit passage of a conductor.

An object of the present disclosure is to provide a control apparatus by which interference between signals can be avoided. A control apparatus (10) according to the present disclosure includes: an instruction unit (11) that instructs a monitoring apparatus to perform processing for monitoring a submarine cable; and a control unit (12) that controls a submarine device connected to the submarine cable. The monitoring apparatus, in response to the instruction given by the instruction unit (11), sends a monitoring signal into the submarine cable and performs the monitoring processing, and the control unit (12) detects a timing at which the monitoring processing is not being executed, and then sends a control signal into the submarine cable and controls the submarine device.

An offshore structure that is a floatable offshore structure that includes at least one submarine cable connector configured to connect a submarine power cable to an electrical device of the offshore structure. The offshore structure also includes at least one messenger line. A first end of the messenger line is fixed to the submarine power cable and a further end of the messenger line is fixed to the offshore structure.

An underwater floating pipeline with the ability to self-maintain desired depth beneath the water giving the ability to connect distant locations. The sections maintain and alter buoyancy for repair and maintenance. Multi chambered pipes allow different rates of flow. Automatic snap-shut doors protect against leaks and loss of pressure. Warning systems alert those in proximity to the pipeline. Freight may use the tunnels to avoid adverse surface weather and high shipping cost and fuel and labour savings.

An example hang-off assembly for a power cable includes a frusto-conical tube configured to be arranged around a length of the power cable comprising at least one cable core and at least one protecting layer radially external to the at least one cable core. The frusto-conical tube is configured to be arranged where the at least one cable core is exposed. The frusto-conical tube is made of two half-shells coupled to each other and defines a first opening and a second opening opposite to the each other. The first opening is circumferentially smaller than the second opening. The hang-off assembly includes a space disposed between the frusto-conical tube and the at least one cable core of the power cable, the space being configured to hold a cured self-curing resin adhering to the at least one cable core.
