Abstract
A system including a modular riser gas handling system configured to couple to and be disposed vertically below a telescoping joint, wherein the modular riser gas handling system includes a diverter assembly configured to couple to and divert a flow of material into and out of a riser, and an annular blow out preventer (BOP) assembly configured to couple to the diverter assembly.
Claims26
A system, comprising:
- a modular riser gas handling system configured to couple to and be disposed vertically below a telescoping joint, wherein the modular riser gas handling system comprises:
- a diverter assembly comprising a first central portion and a plurality of first lines extending between and through an offset pair of first flanges, wherein the diverter assembly is configured to couple to and divert a flow of material into and out of a riser, and wherein the plurality of first lines is spaced circumferentially about the first central portion and the offset pair of first flanges;
- and
- an annular blow out preventer (BOP) assembly comprising a second central portion and a plurality of second lines extending between and through an offset pair of second flanges, wherein the plurality of second lines is spaced circumferentially about the second central portion and the offset pair of second flanges, wherein an adjacent pair of the first and second flanges is configured to couple together the first and second central portions and the plurality of first and second lines of the diverter assembly and the annular BOP, wherein the annular BOP assembly is separable from the diverter assembly, such that the modular riser gas handling system is configured to change a sequence of the annular BOP assembly and the diverter assembly, and wherein the annular BOP assembly and the diverter assembly are configured to be removed from the modular riser gas handling system.

A system, comprising:
- a modular riser gas handling system, comprising:
- a rotating control unit assembly comprising a first central portion and a plurality of first lines extending between and through an offset pair of first flanges, wherein the plurality of first lines is spaced circumferentially about the first central portion and the offset pair of first flanges;
- an annular blow out prevent (BOP) assembly comprising a second central portion and a plurality of second lines extending between and through an offset pair of second flanges, wherein the plurality of second lines is spaced circumferentially about the second central portion and the offset pair of second flanges;
- and
- a diverter assembly comprising a third central portion and a plurality of third lines extending between and through an offset pair of third flanges, wherein the plurality of third lines is spaced circumferentially about the third central portion and the offset pair of third flanges, wherein the diverter assembly excludes an annular BOP, wherein the rotating control unit assembly, the annular BOP assembly, and the diverter assembly are configured to couple together in a stacked arrangement via adjacent pairs of the first, second, and third flanges, wherein the modular riser gas handling system is configured to change a sequence of the rotating control unit assembly, the annular BOP assembly, and the diverter assembly, and wherein the rotating control unit assembly, the annular BOP assembly, and the diverter assembly are configured to be removed from the modular riser gas handling system.
