Flexible subsea slug catcher is designed for use in North Sea's Troll field
Anticipated flow conditions in a future 62-km, 32-in. pipeline for a gas/condensate field in the East Troll area, Norwegian North Sea sector, have prompted the commissioning of a sub sea slug catcher by the field's operator. The resulting design concept can be adopted to handle either natural-gas or crude-oil production. Pipelines carrying two-phase hydrocarbon flow-gas and condensated or crude oil and associated gas-may develop slug flow. The slugs may be terrain-induced, or they may be the result of pigging to clear accumulated liquid. The pipelines may be either offshore or onshore. If offshore, they may deliver either to onshore facilities or to offshore platforms. Design of the appropriate slug catcher naturally depends very much on the system it serves. Onshore, it may consist either of long parallel pipes, a single vessel, or multiple vessels. Offshore, however, slug catchers require compactness and structural unity, characteristics which favor vessels instead of long parallel pipes.
