Expertise Definition

Law firm partners and associates typically come to us with a good idea of the expertise they need. We work with the best, after all.

Complex feats of engineering are, by definition, not cut and dried. In the upstream energy industry, disputes are often as complex as the projects themselves.

Sometimes you simply need an expert with experience of a certain kind of rig, plant, equipment or process. But often the role you think might be the most qualified for your job only understands part of the story. We can add a lot of value early on in the case by helping you identify where the problems arise. Thanks to our PRIMA methodology, we’ve written the book on many kinds of upstream projects. 

Like fingerprints, every case is unique. With years of dispute resolution experience, specific to the energy industry, we can advise you on the technical components that go into a winning strategy.

  • LAW FIRM Slaughter & May / KPMG (for the defendant)

Construction of ultra-deepwater semi-submersible drilling rig

This dispute involved the investigation and negotiation of claims arising from the termination of a drilling topsides construction contract. The claims were mainly construction progress, variations to scope of work, and quantum based. The dispute was settled favourably for our client after our findings were presented. 

Alleged failure to remedy material breach

It’s vital that equipment is maintained in a safe and operational state, so when the managers of a semi-submersible drilling rig were found to have failed to repair certain plant equipment, they were in breach of their contract. The agreement provided a cure period for the breach, so we were engaged to assess whether or not it was possible to repair the plant and equipment within the cure period and whether the rig managers had the right level of competence to effectively manage the repairs.
