Riser fluid handling system

A method of installing an apparatus to handle flow from a subsea component connected by a riser to drilling equipment on a rig, the rig having one or more first lines for communication with the apparatus and having one or more second lines for communication with the subsea component, the method comprising:

• supporting at least a portion of the riser extending below the rig;
• supporting at least a portion of a telescopic joint of the riser above the riser portion;
• moving a package at least having a first sealing device, a flow device, and one or more line segments integrated therein into alignment beneath the telescopic joint portion, the first sealing device configured to control flow through the package;
• connecting an upper end of the package to the telescopic joint portion;
• moving a lower end of the package into alignment above the riser portion;
• connecting the lower end of the package to the riser portion;
• connecting the one or more first lines at least to one or more valves of the flow device of the package, the one or more valves configured to control the flow between the package and the one or more first lines;
• connecting one or more second ends of the one or more line segments to part of the one or more second lines extending along the riser portion;
• connecting a structural support on the riser at a point at least between the package and the telescopic joint;
• and
• connecting one or more first ends of the one or more line segments to another part of the one or more second lines extending between the structural support and the package.

An apparatus to handle flow from a subsea component connected by a riser to drilling equipment on a rig, the rig having one or more first lines for communication with the apparatus and having one or more second lines for communication with the subsea component, the drilling equipment having a drillstring, the apparatus comprising:

• a package having a first end connecting in fluid communication with a first section of the riser relative to the rig and having a second end connecting in fluid communication with a second section of the riser relative to the subsea component;
• a first sealing device integrated into the package and having a first flow bore in fluid communication with the riser, the first sealing device having a first state opening the flow through the first flow bore between the first and second sections of the riser and having a second state at least partially closing the flow through the first flow bore between the first and second sections of the riser;
• a flow device integrated into the package and having a second flow bore in fluid communication with the riser, the flow device having one or more valves in fluid communication with the second flow bore, the one or more valves having a third state permitting the flow between the second flow bore and the one or more first lines and having a fourth state closing the flow between the second flow bore and the one or more first lines;
• one or more line segments integrated into the package and positioned between the first and second ends of the package, the one or more line segments communicating at the first end with the one or more second lines extending from a point along the riser uphole of the package, the one or more line segments communicating at the second end with the one or more second lines extending in communication with the subsea component downhole of the package;
• and
• a control manifold disposed in fluid communication with at least one of the one or more valves of the flow device via the one or more first lines, the control manifold receiving the flow from the at least one valve in the third state and configured to reduce a rate and a pressure of the received flow.
