There is provided high power laser systems, high power laser tools, and methods of using these tools and systems for cutting, sectioning and removing structures objects, and materials, and in particular, for doing so in difficult to access locations and environments, such as offshore, underwater, or in hazardous environments, such as nuclear and chemical facilities. Thus, there is also provided high power laser systems, high power laser tools, and methods of using these systems and tools for removing structures, objects, and materials located offshore, under bodies of water and under the seafloor.

High power laser offshore decommissioning tool, system and methods of use

There are provided high power laser systems for performing decommissioning of structures in land based boreholes, and wells, offshore, and other remote and hazardous locations, and using those system to perform decommissioning operations. In particular embodiments the laser system is a Class I system and reduces emission of materials created during laser cutting operations. The laser systems can include lifting and removal equipment for removing laser sectioned material.

Systems for surface decommissioning of wells

High power laser systems, high power laser tools, and methods of using these tools and systems for opening up damaged wells and for cutting, sectioning and removing structures objects, and materials, and in particular, for doing so in difficult to access locations and environments, such as offshore, underwater, or in hazardous environments, such as nuclear and chemical facilities. And, high power laser systems, high power laser tools, and methods of using these systems and tools for providing rock-to-rock plugs for decommissioning of wells.

A tubular clamp for gripping a tubular is disclosed. In one aspect, a tubular clamp for use with a cutting and lifting system is provided. The tubular clamp is configured to move between an opened position and a closed position. The tubular clamp further includes at least one slip member to permit the clamp to bear the weight of a severed tubular string. Lifting lugs on an outer surface of the clamp permit attachment to a lifting assembly.
