METHOD AND ARRANGEMENT FOR ESTABLISHING AND OPERATING A RISER LESS COILED TUBING |
摘要 |
A method and system are for establishing and operating a riser less coiled tubing intervention arrangement from a surface vessel, the vessel having a deck and a coiled tubing reel holding a coiled tubing, and where a subsea injector is connectable to a head of a subsea borehole. The method includes: arranging; the coiled tubing in a surface injector and the subsea injector, attaching, the surface injector to a lifting tackle of the vessel; after connecting a tool string to the coiled tubing, lowering the coiled tubing tool string and the subsea injector through the sea to the head by running the surface injector while paying out coiled tubing from the coiled tubing reel; and inserting, the tool string in the head and connecting the subsea injector to the head. |
