Underwater marine units (such as remote operated vehicles or small submarines) may be employed to connect the assemblies to each other and to the subsea wellhead equipment. The subsea wellhead equipment includes a carrier line spool (e.g., coiled tubing spool, wireline spool, slickline spool) and equipment to inject a carrier line from the carrier line spool into the subsea well. The carrier line spool can be located underwater, such as on the sea floor or positioned above the subsea wellhead equipment. The carrier line spool can also be located on a sea vessel. Also, to switch tools, a carousel system having multiple chambers containing different types of tools can be used.Field of SearchConnection or disconnection of submerged members remotely controlledWith provision for removal or repositioning of member without removal of other well structure Disconnection With orienting or aligning of member for connection Including means to pull member into position Connection of riser-and-tubing assembly to other structure Connection of guide means Means removably connected to permanent well structure Well component assembly means Multiple wells Assembling well part | |
