BBC: Growth reported in Scottish businesses' oil supply work
Export sales from Scotland's oil and gas supply chain grew to £10bn in 2013, according to figures from Scottish Enterprise.
It calculated that this represented an increase of 22% from the previous year. The research indicated that more than half of work in this area resulted from overseas activity.
The study covered companies which do not extract oil and gas but support those which do. Scottish Enterprise found steady growth in the importance of international contracts. These had risen from 31% of sales in 2002 to 50.2% in 2013.
The figures were revealed at the Offshore Technology Conference at Houston, Texas.
