Decom Engineering makes the cut in Congo decommissioning project success

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 metres 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 workscope 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 workscopes on behalf of major oil and gas operators and contractors including workscopes 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.

Decom Engineering managing director, Sean Conway, said: “Our C1 range of chop saws are firmly established in the decommissioning sector where the nature of the work and complexity of the projects require smart solutions and fresh thinking.

“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 workscopes 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 metres, has multiple buoyancy options, hot stab integration, blade reverse capability and bespoke customisation 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.
