Supply chain collaboration drives efficiencies
With responsibility for all sub-contracted services on the project, Tullow had just one interface. This enabled us to take a holistic approach to optimise operations and maximise collaboration to deliver even greater efficiency.
Throughout each decommissioning phase, our Well Engineering team collaborated with the supply chain to develop a shared approach to risk and reward, meaning those involved were fully invested in safely beating the schedule resulting in significant project savings.
It was this collaboration, that contributed toward successful completion of the three subsea well decommissioning campaigns in successive years within the project budget.
We worked together to implement alternative solutions to mitigate key risks and control project expenditure, from the deployment of air divers from the rig instead of utilising a Dive Support Vessel, to the novel application of a managed pressure drilling spread to mitigate the well re-entry risks of unknown pressure regimes.
Together with our key contractors we also continually improved operational efficiency to reduce the campaign schedule, and overall made material savings which were shared across the supply chain.
