With just two weeks to go before the year end, oil and gas facilities service provider Wood Group believes 2009 earnings will be in line with expectations.It thanked a "robust" performance from its production support related businesses, with development related engineering activities, subsea and pipelines doing well.But it did warn that project delays in upstream and downstream have reduced volumes and margins. Wood sees this trend continuing into 2010 before recovering in the second half of the year. Production Facilities has seen a strong performance during the 12 months, while good progress has been made at the electric submersible pumps business.There have been delays in winning fast track power projects at the gas turbine services unit, despite "reasonable" demand for aftermarket services, although awards are expected to begin in 2010, which should provide good growth in 2011. "Our financial position remains strong and we will deliver good operating cash flow for the year," the firm said. "Overall, we believe our EBITA will be in line with market expectations.""We remain confident in the medium and longer term fundamentals of our key markets and are continuing to develop our business to ensure that we are well positioned to deliver good growth as energy market activity recovers."Results for the 12 months to 31 December are due on 2 March.
