Abstract:
A novel configuration of lightly tensioned or substantially untensioned, i.e. substantially compliant mini-riser is provided to facilitate coiled tubing and/or wireline interventions in rigid catenary riser installations. Those can include in particular clearing hydrates that may accidentally plug risers or subsea pipelines connected to those risers. Existing Intervention Y units can be used, or they can be modified to suit design condition of particular installations. The mini-riser can be used with flexible joint hang-offs, Titanium Stress Joint hang-offs or with novel Spoolflex hang-offs.

Claim (Index 1):
A riser assembly comprising:\n an Intervention \u2018Y\u2019 fitting designed for coiled tubing or wireline operations, a mini-riser connected by a lower end of said mini-riser to a service flange of said Intervention \u2018Y\u2019 fitting designed for said coiled tubing or said wireline operations, said Intervention \u2018Y\u2019 fitting designed for said coiled tubing or said wireline operations being installed in a general area of and connected to a top of a riser including at least one of a rigid catenary riser, or a metallic catenary riser, or a steel catenary riser, or a steel lazy wave riser, or a titanium catenary riser, or a Chinese lantern riser, or a bottom weighed riser, or a fiber reinforced plastic catenary riser, or a fiber reinforced plastic lazy wave riser; wherein said mini-riser is connected above a water surface by an upper end of said mini-riser to a servicing deck attached to at least one of a platform, or a spread moored vessel, or a turret moored vessel, or a disconnectable turret vessel, or an offshore support vessel, or a diving support vessel, or a multipurpose support vessel, or a barge, or a floating buoy, or a submerged buoy, and wherein said mini-riser is substantially compliant between said upper end of said mini-riser and said lower end of said mini-riser.
