Abstract

A hydrate remediation system and method utilizing a concentric coiled tubing downline is provided. The concentric coiled tubing downline includes an outer coiled tubing and an inner coiled tubing, the inner coiled tubing disposed within the outer coiled tubing and extending at least partially through the outer coiled tubing. The concentric coiled tubing downline may be deployed from a single surface reel housed on a surface vessel. A bottom hole assembly (BHA) including a subsea connector is disposed at a distal end of the concentric coiled tubing. The subsea connector of the BHA is configured to be connected to the subsea interface that will be depressurized via the concentric coiled tubing downline. The concentric coiled tubing downline may provide two flow paths. Pressurized gas flows down one flow path, and effluent from the hydrate remediation flows up to the surface via the other flow path.
