2016-10-05 Spain: Development of an Advanced Inorganic Protective Coating Technology for Providing Multifunctional Effects Improving the Problematic in Offshore


 

Development of an Advanced Inorganic Protective Coating Technology for Providing Multifunctional Effects Improving the Problematic in Offshore

Description of the project offered: 
The offshore environment is highly corrosive which poses additional challenges on the coating systems used for protection of man-made structures. Even though milder than in near-shore locations, marine fouling is also an issue off-shore and can dramatically affect the performance of immersed structures.
The reduction of corrosion management capital and operational costs are key to making infrastructures offshore cost-competitive. 
From marine corrosion point of view, seawater environment is divided into four zones, namely, foundations, continuously submerged, splash zone and an atmospheric zone. The corrosion behavior of metals and alloys differs from one zone to another. 
Steel structures situated above the seawater in the so-called atmospheric zone are in a high corrosivity category. The very high corrosion rates are caused by extended periods of wetness and high concentrations of chlorides that accelerate corrosion. Another factor that needs to be considered in the atmospheric zone is UV - light from the sun as this may have a degrading effect on some types of corrosion protection. Area alternately above and below the water line due to the action of waves is called the splash zone, and here the corrosion stresses are even higher. Compared to the atmospheric zone, additional stresses include erosion from the seawater, possible debris and, in some places of the world, even ice. Meanwhile, continuously immersed areas show high corrosion rates and fouling by accumulation of microorganisms. Finally, subsoil area and the foundation of the infrastructures also suffer severe corrosion as well as damage produced by sand and mud erosion and durability problems in concrete structures. 
Many methods had been used to settle the marine corrosion problems. The techniques widely used in corrosion prevention including organic coating and cathodic corrosion protecting. But painting and electrochemical protecting techniques cannot afford an effective protection for steel structure used in the most severe corrosion splash zone. Marine paints are time-consuming to apply and sacrificial anodes have initial costs very high, besides both techniques need frequent, costly inspection and maintenance. 
Thus, this Project proposal presents an innovative approach focused on the development and demonstration of an advanced inorganic protective coating technology which due to the inorganic nature will give longer resistance to environmental aging factors, and which based on nanoparticles inclusions on the formulation will be tailored and designed for providing multifunctional effects in order to solve the specific problematic of each offshore application. In this sense, a multifunctional nanocoating including anti-corrosive and hydrophobic properties as well as adherence to metal substrate will be developed, and in which different nanoparticles will be added in order to give: 1) UV resistance for its application in the atmospheric zones; 2) abrasion resistance and wear for its application in the splash zone and subsoil; 3) anti-fouling properties for its application in the submerged zone. 
In addition, the technology will be developed in order to allow rapid and easy application for maintenance and repair operations, therefore the initials costs and the maintenance will be reduced.
