Ecosea provide a wide range of Urethane coatings suitable for many uses in the oil & gas industry. We are able to provide one of our standard proprietary coatings, or if required we can tailor a product to meet your unique and specific requirements. Our patented Cuprotect® product is an effective, low maintenance, yet extremely long lasting antifoul solution which is second to none. Our range of MetProtect™ moisture cured urethanes are suitable for protecting virtually all steel and metals while Gel-Gard™ was developed specifically as a GRP coating. Whatever your coating requirements may be - we are able to help.

A pipeline with Cuprotect® coated strake is about to go through a ‘Stinger’ test - using a 25 Ton roller press to confirm the durability and

adhesion of Cuprotect®.

Cuprotect® being applied to Risers, Bumper Bars and clamps for Chevron in Australia demonstrates how easy it is to coat complex shapes and curves.

The increasing use of floating production systems (FPS) in the offshore oil industry has driven the  development of various methods and technologies that may have far reaching benefits for both commercial and military ships. The versatility and cost benefits of using FPS units for exploiting deep water and marginal oil fields has made them very attractive to oil companies. However, there have been problems associated with having to dry dock these ships at five-year intervals in order to meet traditional, prescribed class and regulatory requirements.

Excessive biofouling will adversely affect the FPS in several ways; It will place greater stress on moorings, increase inspection times and extend dry docking periods, which in turn will significantly

increase costs by several million dollars.

Operators are seeking a proven, long term fouling control system such as Cuprotect® to minimise

the down time to their valuable offshore assets, caused by biofouling.

Oil drilling platforms are extremely expensive structures which require a great deal of inspection and maintenance if they are to remain in a safe condition. Initially it was not thought that fouling would be a great problem and few precautions were taken against it. However, two problems have become apparent. Although the rigs are normally stationary there can be a considerable tidal flow of water past them and this can be greatly increased under storm conditions. In some waters fouling has been found to be very extensive, especially around the tidal splash zone and this can increase the drag sufficiently to affect rig stability. The pounding of wind and sea on these rigs causes high alternating stresses which can initiate failures in structural members and it is therefore essential to maintain a regular programme of inspection on legs, bracing

struts and the nodes that join them. Only after fouling has been removed can inspection for excessive corrosion or cracks be undertaken.

Biofouling not only makes inspection more difficult but it actually causes anticorrosive coatings to fail, especially in the splash-zone where barnacle shells often cut right through to the steel. This can result in expensive steel replacement for the rig owner. Conventional antifouling paints may be applied during rig construction but they have a limited life, which can be as short as 18 months. After this short period many rigs, especially production platforms, cannot be docked even though they suffer from serious fouling and exploration rigs have to be taken out of service for maintenance that Cuprotect® could make unnecessary. Periodic repainting of the accessible splash zone may preserve the upper parts of the rig legs but this is an extremely expensive undertaking which is not always successful. The lower part of the splash zone is not usually accessible for repainting due to very infrequent calm low tides. Current practice is to add 12 to 16 mm extra to the plate thickness as a corrosion allowance for a reasonable life.

Very high corrosion rates have been encountered with steel riser pipes, due to the higher operating temperature caused by hot oil. Cladding of these with nickel-copper alloy has been proved successful and given the known corrosion and biofouling resistance of 90/10 copper-nickel alloy, it is to be expected that this will be an ideal material for leg cladding. Using Cuprotect® which is manufactured from 90/10 copper-nickel, numerous tests are underway with various oil majors in The Gulf of Mexico, Australia and the Middle East.

Cuprotect® is supplied to the oil industry for application to a variety of subsea equipment. VIV (vortex induced vibration) strakes are used to protect pipelines and cables between offshore installations and the seabed. They are designed to minimise the hydrodynamic effect of vibrations caused by current flow that can result in premature failure of the pipes. Biofouling on the strakes

renders them ineffective after a very short period. Strakes are required to be light but strong and very flexible. Consequently they are made from a variety of materials, normally polyurethane and occasionally polyethylene to which it is extremely difficult (if not impossible) to adhere with conventional anti-foul coatings.

Extensive independent tests conducted by clients have proven Cuprotect® as the ONLY anti-foul coating that meets or exceeds their requirements. For more information on how Cuprotect® or other protective coatings from Ecosea can help you, please CLICK HERE to send us an e-mail.

Most FPS units are ship-shaped and are often based on new build or converted trading tankers. Many FPS units anticipate remaining on station for extended periods (typically several years) without dry docking.  Only Cuprotect® with its proven efficacy and durability, can provide such long lasting anti-foul protection.
