Natural gas production in older United Kingdom North Sea gas fields is tailing off, forcing energy companies to finance major decommissioning works. Platforms and all their gas processing equipment are required by British and Norwegian law to be entirely removed after shutdown right down to the seabed.
Jet Edge abrasive waterjets are perfectly suited to steel-cutting in volatile gas-laden atmospheres. An increasing number of offshore operators are turning to spark-free “cold cutting” to carry out the removal of redundant oil and gas production hardware safely.
Aquablast, Jet Edge’s UK distributor, recently cut up obsolete contractor towers on a live gas platform. The towers operated by the french oil company Perenco in the 40 year-old Indefatigable Gas Field off the Norfolk coast of England, were constructed of 70 mm heavy steel plate (2 3/4 inches think) and weighed in at over 300 tons. Perenco called in Aquablast to cut the towers int smaller cylindrical sections o the platform’s crane could lift the towers on its own.
