AQUASIGN: Combating hazards in a subsea environment

19 September 2019 – No Comments

From conception to the final stages of product testing, AQUASIGN products are designed to minimise the safety risks associated with working with assets in a subsea environment.

But what are the common hazards of working in a subsea environment? And how exactly do Aquasign anti-fouling markers help to combat those?

Personnel safety

When an asset is located in shallow waters, it’s up to divers to go down and take a look – whether that’s for a routine check or because something’s gone wrong.

Traditional signage with no anti-fouling properties can be hard to spot, forcing your diver to spend longer under the water in an attempt to locate the correct component.

Markers partially obscured by marine growth can also be misread, potentially leading to bigger problems when components on manned assets, such as platforms and vessels, are misidentified.

ROV problems

Remote operated vehicles (ROVs) are seriously expensive bits of kit. So when you send an ROV down to carry out maintenance on a deepwater asset, you want it back on the surface as quickly as possible.

Aquasign markers are easy for ROVs to spot. Our high-contrast colourway stays clearly visible, even after years underwater and in low visibility marine environments. So your ROV can get in, do the job, and get out.

Accessibility

Marine growth doesn’t just impede visibility – it can cause serious problems when it comes to accessing particular components on your subsea asset.

Aquasign markers keep key valves and critical moving pieces as accessible as possible by inhibiting the marine growth that can obscure and block them. And improved accessibility means easier, more effective maintenance.

Even on large subsea structures, where divers and ROVs need to get within frames and inside compartments, Aquasign is there to make life easier.

Environmental risks

Personnel safety is always top of the list when it comes to assessing the risk involved in any subsea activity.

But what about the wider environmental implications of incorrectly identified or inadequately maintained structural components?

The BP Deepwater Horizon oil spill is surely the most devastating recent subsea disaster, with almost 5million barrels of crude spilt out in the marine environment, not to mention the personnel who were killed and injured.

Tethers: a lifeline for divers and ROVs

Further to those previous points, tethers and cables are a critical part of any subsea activity: they’re a lifeline to the individual or vehicle carrying out maintenance on a submerged asset.

So, it’s vital that these tethers and cables can be quickly and easily identified at any point. That’s why AQUASIGN has developed a flexible marker that can be fitted securely to these components.

We’re in the final stages of our live trials, and will be launching these groundbreaking markers in the next few months.

Relative dangers

Whether your asset is big or small, in shallow or deep water, the subsea environment poses major risks to subsea oil and gas operations.

Initial surveys, drilling, installation, maintenance and repair, and decommissioning: thorough planning and risk analysis, is essential for every operator.

And while the hazards caused by excessive marine growth are somewhat lessened in deepwater applications, the dangers associated with this dark, cold and remote environment itself increase.

In both shallow and deep water, Aquasign helps to keep you as safe as possible.

High visibility, long-term sticking power, flexible application, and a variety of adhesive and mechanical installation options: our markers are designed to fit every project perfectly.
