Manage offshore complexity with onshore confidence

You know your onshore grid inside out. Offshore is a different story. As offshore infrastructure, such as substations, export cables and HVDC interconnections become part of your grid, a hard truth emerges: onshore experience doesn’t transfer. Offinity gives you what you’re missing: proven offshore operational knowledge, delivered as a platform, in a matter of weeks.

The offshore
knowledge gap
is real

Offshore isn’t just onshore at sea. It’s marine logistics, remote asset integrity, OT security, and multi-partner coordination under strict regulatory pressure. Most TSOs are stepping into this without the processes, the know-how, or the tools to manage it confidently.

Key challenges include:

  • Limited in-house offshore know-how
  • Marine coordination across vessels and contractors
  • Export cable and OSS integrity monitoring
  • Health & safety in remote maritime environments
  • Gaps in OT security oversight
  • Increasing NIS2, IEC62443 and audit pressure
