An uninterruptible power supply, UPS, arrangement for subsea applications, including a container arranged and configured for subsea operation, and the following main modules arranged inside the container: at least one battery module of a predetermined battery capacity; at least one UPS module governing the battery module, the UPS module having a predetermined UPS capacity; at least one control module configured for interfacing and managing the battery module and the UPS module. The UPS arrangement is arranged and configured to vary its overall capacity based on at least the number of battery and UPS modules, wherein the at least one battery module and the at least one UPS module are internally arranged such that the heat losses from the UPS module are used to heat the battery module.

Uninterruptible power supply arrangement for subsea applications

A medium voltage circuit breaker in a high pressure subsea environment includes: a vacuum circuit breaker; and a drive in a pressure tight housing. For an electrical three-phase arrangement, one vacuum circuit breaker per phase is arranged in a separate pole housing each, and the resulting three pole housings are mounted to a common base compartment, in which three drives for the three vacuum circuit breakers are arranged. The three pole housings and the common base compartment are attached such that they commonly form a pressure tight compartment.

Medium voltage circuit breaker in subsea environment

A subsea circuit breaker for a subsea power distribution system. The subsea circuit breaker includes a circuit breaker enclosure, first and second contacts and an electro-mechanical actuator. The subsea circuit breaker is also furnished with a mechanical transmission mechanism for opening or closing the contacts in response to a mechanical command operation from the outside of the circuit breaker enclosure.
