OPERATIONS & MAINTENANCE
Oxifree’s coating is used globally to halt the issue of CUPS
the clamp to also move within the TM198. Tis makes it suitable for a wide range of piping where pipes expand and contract or subject to vibration, even on FPSOs. Indeed, the coating is now being used globally to halt the issue of CUPS for oil and gas majors. Whereas other solutions require
a shutdown and take time to install, the Oxifree coating can be applied to live pipework and provides protection immediately, as it cools on impact, saving considerable downtime cost, and no
disruption to production. Tis makes it complementary to (applied alongside and/ or over) other protective solutions. Once the pipe, saddle and clamp
are encapsulated, the surface within is protected from moisture and oxygen protecting it from further degradation. Tis novel solution is only applied once and will provide many years of protection in the harshest of environments. Should inspection be required this can be done through the coating with the use of NDT/ ANDT inspection techniques (such as
UT) or a small area cut away from the coating for visual inspection and can simply be refilled/resealed. Te oil & gas industry is still facing the challenge to reduce unnecessary expenditure and make critical savings to maintenance, while increasing safety and reducing ecological impact. Extending asset lifespan without operational shutdown is the fundamental way forward. Creating a culture of prevention with new technologies will be the ultimate solution.
THE COATING IN ACTION O
xifree Global Services recently performed work for a large energy supplier in the
Netherlands. The work involved protecting flange connections on a riser turret on an unmanned OLT. A small team of two personnel
were mobilised via a ‘walk to work’ system provided by a service support vessel. With bedspace at a premium a small team was a major advantage.
Oxifree’s application technician
completed the project in just two days, applying TM198 directly onto each of the flange assemblies, as requested by the client. Nine flanges were coated using
the new Polymelt 50 application machine with a 15m hose. This machine has a small footprint, making it ideal for the platform size. The surface preparation was minimal, a wire brush was used
to remove the loose debris, no degreasing or blasting was required and no habitat needed to catch any coating or blasting materials. The project was a great demonstration of how TM198 can provide a cost effective, no waste and speedy, space efficient solution to the problem. The technology was able to tick many boxes that are typically prohibitive to all services in this environment.
