CLS Offshore has won a major contract to carry out remedial work as part of a improvement project by southern North Sea production company Perenco.

The oil, gas and wind energy business said that work on Perenco's Leman 27 Bravo platform, off the coast of Norfolk, will ensure that where identified remedial work was undertaken and platforms continue to operate to Perenco's standard now and in the future.

It comes after CLS Offshore completed a similar project for Perenco on the 23 Charlie platform in the Inde field.

Scott McMillan, CLS managing director, said: 'It's significant business for us and, hopefully, potential work way into the future. There are approximately 400 platforms to eventually be decommissioned within the North Sea and the remaining platforms are predicted to continue operating into 2040.' He added that with enhanced recovery techniques allowing continued extraction, platform life extension would be paramount.

Last year CLS Offshore moved into a new headquarters in modernised former council offices off Malthouse Lane in Great Yarmouth after a �300,000 investment.

Mr McMillan said: 'Our quayside facility, with easy access to the North Sea, provides the perfect support solution for activities of this type.

'We anticipate that this type of work will continue well into future decades if the long-term price of hydrocarbons remains high and technology further improves to allow the extraction of more gas.'

The completed work on 23C included the removal of redundant process equipment items such as contactor vessels and their associated pipework, as part of an overall integrated plan.

CLS Offshore engineered the rigging solutions which included designing and fabricating the supporting transit framework for transferring the contactors to the supply vessel and onward shipment to shore.

Mr McMillan added: 'This piece of work was executed to the highest safety standards and to our client's timescales and planning requirements.

'This workscope was important to our client and their commitment to asset integrity.'

Today CLS earns about 30pc of its turnover from asset integrity and decommissioning work, a sector it is ambitious to develop further.
