Inspecting a Jacket structure costs enormous ammounts of CO2
This does not come from the inspection itself
But rather the IMR vessel used to transport and operate the work class ROV
It does not have to be like that

The Quiet Carbon-Cost of Inspections
Every platform, pipeline and wind turbine at sea has to be checked for damage on a regular basis. The normal way of doing that costs more than most think, and not just in money. Here is what it costs the air and the sea, and how we do it differently.

Jacket Inspection with ROVs:
What Determines the Choice of Method and Vehicle Class?
And still save of money doing a beter job!
Steel substructures – known as jackets – are among the most safety-critical structures in the offshore industry. Regular inspection of welds, nodes, members and cathodic protection is not just good practice; it is a requirement within integrity management. How the inspection is actually carried out, and which ROV class is used, is a decision with greater consequences than many assume. This article takes a closer look at the trade-offs behind that method choice.
What a Jacket Inspection Actually Involves
Inspecting a substructure is primarily about documenting structural condition and corrosion protection. The most common tasks are:
- GVI (General Visual Inspection) – an overall visual review to detect visible damage, marine growth or anomalies.
- CVI (Close Visual Inspection) – close-range visual inspection of selected points, typically welds and nodes.
- CP survey (cathodic protection) – potential measurements to verify that anodes and corrosion protection are working.
Newer approaches supplement this with photogrammetry for 3D modelling, and field gradient methods that map CP condition without physical contact. What these tasks have in common is that, at their core, they are about observing and measuring – not about intervening in the structure.

The Smart Choice for Subsea Integrity
To save the planet we all need to
The beter way to inspect
When you order an inspection from BeyonC doesn’t use large support vessels for subsea inspections. We use compact mini-ROVs instead, which cuts CO2 emissions by up to 90% and causes a lot less disturbance to marine wildlife
