Abstract: An inlet device to a separator including a generally tubular outer wall and a generally tubular inner wall. The walls define at least a part of a first annular path between them. An inlet opening provides for the passage of a fluid through the outer wall into the first annular path. At least one communication channel provides for the passage of a fluid from the first annular path into the second annular path. At least one movable closing element provides for at least partial closure of the fluid passage from the first path into the second path. The communication channel(s) is/are arranged to extend along the outside of the inner wall downwards from the first path into the second path, wherein the second path is arranged below the first path.

Abstract: A method for generating power at sub sea level. An oxidizing fluid and oxidizer are fed separately for mixing at a sub sea station. The oxidizing fluid and oxidizer are chosen for chemical reaction in situ under the release of energy. The energy so produced is fed to drive means operated by at least one of heat, kinetic energy, pressure and electricity, and operative to drive sub sea processes or/and sub sea production equipment. An apparatus for generating power at sub sea level. The apparatus includes separate supplies of an oxidizing fluid and an oxidizer for mixing at a sub sea station. The oxidizing fluid and oxidizer are chosen for chemical reaction in situ under the release of energy. A feed for feeding the energy so produced to a drive operated by at least one of heat, kinetic energy, pressure and electricity.
