ABERDEEN-based Wood Group PSN (WGPSN) has continued its run of contract successes in 2013 after extending its deal to provide operations and maintenance services to ConocoPhillips' 50 assets in the southern and central North Sea.

The £40 million extension, which will also see WGPSN provide services to the energy firm's Theddlethorpe onshore gas terminal in Lincolnshire, is a further vote of confidence the North Sea oil and gas services sector.

It is also a significant boost to employment, with the contract supported by 150 onshore and 280 offshore jobs in the UK.

The contract is described by WGPSN as one of its most complex projects, with its work spread over 50 manned and unmanned facilities.

It is also one of its longest running, having held the contract since 1992.

The renewal follows a host contract extensions won by WGPSN this year, with the firm having already secured further work with CNR, Total, Teekey and Ithaca Energy already in 2013.

The Ithaca deal, which safeguarded 200 jobs, was the first life of field contract won by the firm.

It will see WGSPN operate and deliver managed services to the Beatrice offshore platforms in the inner Moray Firth and Nigg onshore terminal until the end of their operating lives.

The deal is expected to be worth £140m to the firm.

This year's contract wins mark the continuing importance of WGPSN to its parent group, with the division now employing more than 28,000 staff in around 35 countries.

Dave Stewart, UK managing director for WGPSN, said: "We are proud to have worked with ConocoPhillips (UK) for more than 20 years and continue this long-term relationship.

"The ConocoPhillips project is a key contract in our UK portfolio and we are pleased to receive this extension and further enhance our reputation with a major international company."

ConocoPhillips declined to comment on the contract extension.
