Turnarounds & Modifications


Minimize downtime, Maximize performance

Plant turnaround and modification processes are complex and multidisciplinary and can mean costly lost production. Stork’s in-depth expertise in turnaround management minimizes shutdown time and costs without compromising on safety and quality, while often improving asset performance by concurrently executing modification scopes. For Stork's turnaround and modification professionals no project is too big or too small.

  • Preparation & planning
  • Detail estimating
  • Total execution, including all staffing and equipment
  • Close-out

Turnaround & Modification scope definition

The cost and success of a turnaround or modification depends strongly on the right scope definition. Therefore we start by focusing on the reduction of scope within the shutdown window, making the process simpler, more transparent and more efficient. We listen to your needs and develop a plan to ensure efficiency in the turnaround, extend maintenance intervals and optimize your total cost of operation.

Our support extends from the scoping phase of the individual shutdown, through work preparation and execution delivery, right through to close-out. A thorough close-out enables us to capture vital plant information and shutdown metrics. These enable us to continuously improve on safety, costs and planning in your next shutdown, regardless of location.

We have delivered more than 2,500 turnarounds and established an unrivalled track record in the many industries we serve.
