Decom Engineering’s (Decom) specialist cutting technology has been successfully deployed on a decommissioning project offshore West Africa.

Decom deployed its C1-24 chop saw in water depths of up to 1,050 meters as part of an operation to recover a jumper connector on behalf of Total Energies in the Gulf of Guinea, offshore the Democratic Republic of Congo.

The work scope included the cutting of the insulated 6” Duplex flowline at each end of the jumper, with the chop saw deployed by ROV with hot stab capability, and using a Tungsten Carbon Tip blade with an average cutting time of 1 hour 15 minutes.

The Congo project follows other successful work scopes on behalf of major oil and gas operators and contractors including work scopes in the North Sea, Mauritania, Norway, and Gulf of Thailand.

Established in the United Kingdom in 2011 and with bases in Aberdeen and Belfast, Decom is an R&D specialist focusing on the design and fabrication of cutting solutions and innovative decommissioning equipment, with a growing reputation for providing complex deep water project solutions.

“Our latest project in deep water offshore DCR is another tick in the box for the versatility, safety and efficiency of our cutting technologies, adding to an extensive track record of completed work scopes in the major hydrocarbon producing regions.

“Decommissioning redundant piping infrastructure or repurposing assets to be converted for low or zero carbon energy storage is a massive global market, and we are committed to investing in research and development to ensure our clients have the most sustainable means at their disposal to address their needs.”

The C-1 chop saw range is certified for use in water depths of up to 2,000 meters, has multiple buoyancy options, hot stab integration, blade reverse capability and bespoke customization capabilities.

Decom are expanding its C1 chop saw range with development of new model which will be capable of cutting piping infrastructure of up to 46” in diameter.
