Roxar Flow Measurement as

Rolf Wium

Valve for throttling the flow rate of a fluid, distinguished in that it comprises a bolt (), a pipe section () having inner dimension adapted to enclose the bolt sealingly, a groove () in at least one of the outer surface of the bolt and the inner surface of the pipe section, the groove providing a fluid passageway between the enclosed bolt and pipe section, an inlet port having fluid connection to an upstream end of the groove, an outlet port having fluid connection to a downstream end of the groove, and means to adjust a coaxial position of the bolt () relative to the pipe (), by moving one or both of the bolt and pipe section, in order to adjust the throttling effect of the valve. System comprising valves of the invention.

Valve for subsea hydrate inhibitor injection

An apparatus and a method for its use allow selective installation and removal of a canister such as one containing interface electronics to a mating connector on a housing, such as one containing a subsea multiphase flow meter sensor. The separately retrievable canister may contain multiphase flow meter detector electronics and is sealed, waterproof, and preferably light-weight. Installation and retrieval may be via use of an ROV and an alignment guide which acts as a guide to aid in correct positioning of the canister. The canister may be cooled by surrounding sea water and/or by insulation.
