摘要： A water treatment subsea installation and method are disclosed, adapted for scaling prevention and treatment of raw seawater into process water suitable for use in subsea hydrocarbon production. The water treatment installation comprises a seawater inlet to a primary filtration unit wherein a filtration membrane separates a receiving chamber from a permeate chamber having an outlet for treated water. A pump is installed in fluid flow communication with the treated water outlet, a recirculation loop feeding a portion of the treated water via a subsea electro-chlorinator back to the water stream upstream or downstream of the membrane of the primary filtration unit, and a secondary filtration unit is installed in the treated water stream between the primary filtration unit and the electro-chlorinator.

摘要： A horizontal connection system including: a first holding unit, to which a first hub is fixed; a second holding unit, to which a second hub is fixed; a heat bank including a casing with a rear part secured to the first holding unit and a front part releasably connectable to the rear part; and a clamp connector secured to the first holding unit and received inside the heat bank. The parts of the casing are temporarily fixed to each other by connecting members extending between the parts on the outside thereof. The front part of the casing is provided with fastening members configured to come into engagement with associated fastening members on the second holding unit, to thereby allow the front part to be secured to the second holding unit, when the front part and the second holding unit are brought into contact with each other.

摘要： A sensor (4) for monitoring cathodic protection (CP) levels, i.e. cathodic protection potential and current capacity, the sensor being arranged to perform measurements of galvanic current and polarized potential between, on one hand, a reference object and, on the other hand, one of: i) a sacrificial anode (2) and ii) a protected component (1). The sensor comprises a reference electrode (5) in electrical and electrochemical contact with a metal sensing element (6) which has a defined surface area (6′) exposed to an electrolyte, the sensing element electrically coupled to one of the sacrificial anode (2) or the protected component (1) via a resistor (15) and a switch (12).

摘要： A vertical connection system for subsea connection of a first tubular member to a second tubular member, the system comprising a lower coupling member comprising an upright casing which encloses a liquid-filled space, wherein a hub of the first tubular member is fixed to the casing at an upper end thereof and the first tubular member extends through said space; and an upper coupling member, which comprises a guide frame configured to slidingly receive said casing when the upper coupling member is lowered downwards onto the lower coupling member, wherein a hub of the second tubular member is fixed to the upper coupling member. The guide frame is provided with a layer of thermally insulating material on its outside. The liquid-filled space is delimited downwards by a bottom wall formed by thermally insulating material or covered by a layer of thermally insulating material.

摘要： A hydraulic tool for use with a clamp connector where a first clamping element and a second clamping element of the clamp connector are pivotable towards each other into a closed position by exerting a pulling force on an operating shaft and a pushing force on a spacer sleeve, and where said first and second clamping elements are lockable in said closed position by tightening a locking nut against a shoulder on the spacer sleeve. The tool includes a pulling element; a hydraulic power unit for moving the pulling element in relation to the spacer sleeve and thereby allow the hydraulic tool to exert a pulling force on the operating shaft and a pushing force on the spacer sleeve; a rotatable actuating member with a socket engageable with the locking nut; and a drive motor for rotating the actuating member to allow the actuating member to rotate the locking nut.

摘要： A system and a method for seawater pre-treatment and injection are disclosed. The seawater pre-treatment and injection system comprises at least one subsea water well connectable to a seawater injection system comprising at least a water injection pump in flow communication with a water injection well, wherein the subsea water well is made as a hole into a groundwater holding strata under the mud-line with a water permeable or non-permeable completion using the seafloor soil for filtration, with an inner tubing connectable to the seawater injection system via a valve.
