⚠ Illustrative viewpoint, written to demonstrate the resource hub.
The rules around what you can put in the water column are moving in one direction: tighter. For anyone specifying subsea identification, that quietly changes the calculus in favour of non-toxic, maintenance-free materials.
Biofouling has always been an operational nuisance. Increasingly it is also a regulatory and environmental concern. Guidance associated with the International Maritime Organization on biofouling, and the broader environmental expectations across the North Sea and renewables, are pushing operators to think harder about what their subsea hardware sheds into the water, and about the biocides used to keep things clean.
Why it matters for identification
Marking is a small part of a subsea scope, but it is not exempt. Coatings and anti-fouling treatments that rely on biocides are exactly the sort of thing that comes under scrutiny. A marker that leaches nothing, needs no cleaning, and still stays legible for decades sits comfortably on the right side of that trend.
Non-toxic, maintenance-free identification used to be a nice-to-have. It is becoming a line in the specification.
The practical read
For offshore wind in particular, where environmental credentials are part of the value proposition, specifying identification that is 100% non-toxic and never needs a cleaning intervention is an easy win. It removes a small compliance question, and it removes a recurring operation from assets nobody wants to revisit. That is the case Aquasign's oil-exuding silicone was built for.
