Fluid diverter system for a drilling facility

摘要

A fluid diverter system for a drilling facility comprises a diverter housing (15; 15′) fluidly connected to a tubular (3, 42, 43) extending to a subsea well. The diverter housing (15; 15′) comprising a movable diverter element (2) for closing off the diverter housing, a first fluid conduit (44) connected to a mud system and comprising a first valve (5), at least one second fluid conduit (20; 20′) leading from an outlet (46; 46′) in the diverter housing to an overboard location and comprising a second valve (1; 48), and a third fluid conduit (16) connected to a mud/gas separator (MGS) (13) and comprising a third valve (4). The MGS (13) is arranged below the outlet (50) of the diverter line, whereby riser fluids may be fed from the diverter housing (15) to the MGS (13) by means of gravity flow. The diverter valve (1; 48) on a leeward side of the drilling facility is configured to be open before the diverter element (2) closes around the tubular (3).
