Once a project is up and running, the nature of the work around it changes. The day-to-day responsibilities associated with the project pass from P&T to one of Shell’s main businesses: Integrated Gas, Upstream or Downstream. Still, P&T can remain involved. About 15% of all work done by P&T relates to asset support aimed at upholding operational excellence. P&T seeks to deliver these services in an integrated, productive and cost-effective way.
