Ireland-based offshore decommissioning technology firm Decom Engineering has reportedly developed its largest Chopsaw in response to client demand for larger-sized subsea pipe-cutting capability.

The C1-46 Chopsaw has been designed to cut tubulars and other materials up to 46 inches, and it can cut a wide range of materials, including Inconel alloys, duplex and concrete.

According to Decom Engineering, the new Chopsaw can be operated in water depths of up to 2,000 meters. The new Chopsaw is currently deployed on its first project, which involves cutting large surface-laid pipelines (36 inches) with 57 mm concrete coating, along with other large pipelines.

"With the ability to cut in any orientation, the C1-46 is capable of multiple cuts per blade (20-100), resulting in large cost savings and increased efficiency. Blade changes are efficient, safe and the Chopsaw can be supplied set up in a number of configurations and settings to suit project requirements," Decom Engineering said.

"Multiple lifting points located around the tool allow a highly versatile angle of deployment and an array of cuts can be completed whilst subsea or held in wet storage, without returning to the surface. The tungsten carbide tipped saw, which can be operated topside or by ROV (with hot stab capability), is highly adaptable to suit challenging surroundings and varied structures," the company added.
