PDi have a successful track record of supporting both international and North Sea operators in all aspects of decommissioning.


PDi has delivered decommissioning projects for over ten years and so substantial decommissioning expertise has been developed within the organisation. Applying this we have helped clients to successfully obtain approval of decommissioning programmes, maintain safety performance and reduce project risk & cost.

Our team has extensive experience of providing decommissioning engineering consultancy services for the global oil and gas industry. This includes comparative assessments, decommissioning studies, cost estimates and decommissioning execution support.

Our decommissioning scopes have covered FPSO’s, steel platforms and CGBS, subsea pipelines, bundles, umbilicals, structures and all associated subsea facilities, with project locations covering the UKCS, Ireland, India and Africa.

Utilising the full range of discipline engineering capabilities, a selection of typical decommissioning work scopes performed by PDi are shown below.

PDi Compare

PDi has developed a software tool, PDi Compare, to record, compare and report the findings of the comparative assessment process typical of decommissioning projects. This can easily be tailored to meet client and project requirements both in terms of how the options are quantified and how the criteria are weighted. The process is completely flexible and can be adjusted to reflect agreed criteria.
