Since 1982, there has been a move to Thermal Sprayed Aluminum (TSA) coating in the “splash zone” of offshore structures. Our experience indicates that an experience applicator, good surface preparation and quality of wire combined to achieve required thickness and apply the sealer to seal the entire surface.

Corrosion can seriously damage the substrate and can lead to significant repair or replacement costs. Good corrosion protection for metal coatings is traditionally achieved through two component (2K) systems. However, they show certain disadvantages that do not exist for one component (1K) systems.
This AMPP standard provides a series of effective and economical test methods to evaluate the performance of candidate offshore platform new construction and maintenance coatings. The testing protocol is established to simulate the offshore environment and based on the major failure modes observed on offshore platforms. The test results will rank the candidate coating systems for end-users to select and coating manufacturers to develop reliable coating systems.
The nature and rate of corrosion of a metal depend upon –among other factors- the corrosivity of the environment to which it is exposed. The corrosivity category is a technical characteristic that provides a basis for the selection of materials and protective measures in different environments subject to the demands of the specific application, particularly concerning service life. Data on the corrosivity of the atmosphere is essential for the development and specification of optimized corrosion protection for manufactured products.
Two coatings were developed for the intended purpose of maintaining steel sheet pile at the waterfront. The new splash zone coatings are free of VOC’s and HAP’s thereby providing a more environmentally friendly alternative to the standard coal tar epoxy system. The new coatings are also more abrasion and impact resistant and applied at more than twice the thickness of coal tar epoxy. All of these factors add up to an anticipated service life of 3 to 4 times that of coal tar epoxy leading to reduced life cycle costs.
Splash and immersion zones on offshore installations are areas that are exposed to extremely aggressive environments due to the effects of sea water, tides, wind, waves, and/or ultraviolet radiation. Various certifications such as NORSOK(1) exist to help guide customers select a coating based on its corrosion resistance performance. Despite the necessity of these standards, it is helpful to understand that other properties such as substrate surface and cure conditions can greatly effect performance of the coatings. In this paper, we will compare adhesion of two coatings to different substrate surface conditions while both coatings will be cured in two different environments. Our goal is to investigate the effect of curing environment of coatings on adhesion to the substrate.
Following the worlds growing need for sustainable energy solutions, offshore wind farms are important contributions to the generation of renewable energy. One key element for a profitable and sustainable operation of offshore wind farms is that the installations are protected with the most cost-effective corrosion protective solution for the entire lifetime. In practice, this means that today’s projects are planned with an estimated lifetime of a minimum of 25 years without major maintenance of the corrosion protective solution.
