A successful turnaround depends heavily on having the right partner and the right scope definition, we focus on the preparation and execution phase of large turnarounds to help our clients reduce the shutdown window.
During the lifecycle of your asset it requires regular shutdowns to allow for modifications, maintenance, and repair work. At D&D we ensure that this is realised within the set time and budget and assure that the work meets the
relevant quality requirements. Reliability of your asset’s performance after start-up is critical to our success.
