Good activity in Europe, the Middle East, Africa and the Caspian hascontributed to growth in our subsea business, although in other markets we haveseen some impact from the completion of existing projects. Onshore pipelinescontinues to perform well in the US, as a result of continued strength in shaleactivity. Downstream is benefitting from brownfield work in US refining and somegreenfield activity in the chemicals market. Wood Group PSN Production Services1 Growth in the first half has been led by performance in the Americas,principally in the US shale regions where we invested further in ourfabrication and training capabilities and now have over 5,000 personnel. Wehave seen good organic growth in US shale, together with a significantcontribution from Elkhorn, which was acquired in 2013. Underlying performance in the North Sea remains strong in an environment whereoperators are increasing their focus on efficiency.

Overall forTurbine Joint Ventures we expect some improvement in performance in the secondhalf although not to the level originally anticipated. The Dorad contract sits outside of our Turbine Joint Ventures. Customerhandover was achieved in the second half of May. Overall, the contract isprofitable, although delayed customer handover contributed to a year to dateloss.
