Ayman Asfari, Group Chief Executive said: "2011 has been an important year for us, with good operational performance across our portfolio of projects, the rolling out of Integrated Energy Services (IES) and positive initial progress in delivering our IES strategy."During the year we also set out our medium-term target of more than doubling our recurring 2010 group earnings by 2015. The extensive pipeline of new bidding opportunities, our strong financial position together with our differentiated and competitive offering and proven track record in project execution increase our confidence in achieving that goal. "In 2012, we expect to make further progress towards this ambition, with net profit expected to grow by at least 15%."JH/NR
