With the inclusion of INTECSEA, Advisian is uniquely qualified to support large-scale offshore and deepwater hydrocarbon developments.

Advisian and its INTECSEA division are global leaders in subsea systems, offshore pipelines, floating systems and overall field development, and our topside specialists are among a select few with the experience to support the world’s largest, most complex integrated float-over decks (IFDs).

The group’s breadth of expertise includes:

  • Field development planning and concept selection

Our technical and commercial strength combined with vast project real-world experience helps reduce uncertainty and ensures our clients get the most value out of their assets.
