There has been a major increase in upstream activity and development investment in the UK and Norway over the past five years. This has led to a tight supply chain, cost inflation, delays and the erosion of project returns. As a result, industry is increasingly focused on project execution performance. Of the 100 new field developments sanctioned or brought onstream between 2009 and 2013, 74% are over budget and 70% are delayed. The average cost overrun is 18% and delay is six months.
