Diverter system is used on platforms and jackup rigs to protect against shallow gas kicks during drilling operations. In the event of a shallow gas kick, the diverter is energized to seal around the drill pipe and divert the gas safely overboard.
Features and benefits
• Complete protection while running casing strings and drilling hole is provided by a full range of insert packer sizes, all of which use a “J” type running tool
• Available with a rotating insert which provides low pressure packoff on the kelly or drill pipe during drilling
• Fixed support housing, a proprietary feature, is securely bolted to the rotary beams and provides fixed outlets for flowline, fill-up line and vent lines KFDJ diverter All dimensions in inches.
• Support housing allows installation of outlets up to 20” diameter to virtually any configuration
• Diverter, spacer spool and overshot packer assembly may be pulled or run without connecting or disconnecting the flowline, fill-up line and vent lines • Mudline suspension hangers and bit sizes up to 27.41” for 37-1/2” rotaries or 36.41” for 49-1/2” rotaries can be run without removing the diverter assembly
• Diverter, spacer spool and overshot packer each fit through a 37-1/2” rotary table. Minimum bore through the standard support housing is 36-1/2” ID for the 37-1/2” in rotary installation. Optional 37-1/2” bore is available • Overshot packer on the bottom of the diverter spacer spool assembly reduces the nipple-up time normally required to weld flanges or hubs to casing
