A mounting assembly is for a power pedestal including a number of electrical components. The mounting assembly includes a plurality of mounting members including a first mounting member and a second mounting member each structured to engage an elongated support member and be coupled to the elongated support member. The elongated support member has an end portion. The plurality of mounting members are cooperatively structured to enclose the end portion.

A vault system is provided that defines an enclosed volume to protect various electrical, water, communications and other components. The system comprises a lid to allow selective access to the contents in the enclosed volume of the vault. Over time, continued wear and tear on the lid of the vault can cause the lid to deflect inward and/or cause the body of the vault to deflect outward, which compromises the integrity of the vault. Interlock features, methods, and systems are provided transfer stress and strain between the lid and the vault, which maintain the integrity of the selective interconnection between the lid and the vault.

The present invention relates to a power collection system for subsea collection of power from offshore power generation units, the system including: a set of power extender modules being independently arrangeable subsea in a local grid and each being connectable with a respective one of a set of offshore power generation units to collect electrical power from the respective offshore power generation units, the set of power extender modules being configured to be electrically series connected in the local grid being connectable with a power consumer.

An umbilical for use in the offshore production of hydrocarbons, the umbilical comprising at least one electric cable, the electric cable comprising at least one electric conductor (18), and at least one electric conductor (18) comprising plurality of electric strands having interstices (15), wherein the interstices are filled with a metal-based material. In this way, there is provided an umbilical with a void-free1 or completely gap-filled conductor construction which therefore prevents water or gas migration or transport along such a conductor.

A subsea power distribution device and system. The subsea power distribution device includes a first watertight housing accommodating at least one transformer, having a primary winding and at least one secondary winding, input terminals electrically connected to the primary winding and arranged to be connected to a remote power supply, an output terminals electrically connected to the at least one secondary winding, and switches located within the first watertight housing and arranged to open and close the connections between each secondary winding and a corresponding output terminal. Each output terminal is further connected to an overcurrent breaking device which is further arranged to be connected to a subsea power consuming device. The overcurrent breaking device is arranged in a second watertight housing separate from the first watertight housing and is filled with insulating liquid.
