Recently, "Haiji No. 1", a deep-water jacket designed and built by China, was successfully installed in the waters of the Pearl River Estuary Basin in the eastern part of the South China Sea, setting a new record for offshore installation of deep-water jackets in Asia, marking that the complete set of key technologies and installation capabilities of China's deep-water ultra-large jacket have reached the world-class level. It has important strategic significance to promote the increase of offshore oil and gas storage and production and ensure national energy security.

    According to the People's Daily report, "Sea No. 1" is the first 300-meter-class deepwater jacket in Asia, with a total height of 302 meters and a weight of 30,000 tons, and the first application of intelligent monitoring, digital twin and other technologies, can withstand the harsh sea conditions once in a hundred years. So the question comes, for such huge, harsh working environment, high stability requirements of Marine facilities and equipment, how to design and consider protection and maintenance work, in order to ensure its safe, stable and efficient work?

    The part of the Marine engineering operation platform soaked in seawater will be worn and corroded due to long-term continuous seawater erosion and bioadhesion, while the part exposed to the Marine atmospheric environment will age rapidly due to waves splashing, tidal range changes, frequent dry and wet alternations, and high thermal radiation. In general, one of the starting points for the protection and maintenance of offshore platforms is anti-wear and anti-corrosion. At the same time, because the Marine operation platform is a large volume, and is located in the far sea, and is frequently subjected to adverse stimuli for a long time, the protection and maintenance work is best to achieve the effect of a single operation and long-term effect to avoid unnecessary time and energy consumption. In addition, it is necessary to eliminate the use of equipment and raw materials that pollute the Marine environment, which is more conducive to the protection of Marine security and the development of Marine economy. Therefore, the key words of protection and maintenance are "anti-wear and anti-corrosion", "efficient" and "environmental protection".

    The polymer nano hydrophobic heavy anti-corrosion coating produced by Titanian Technology is designed and developed from the above situation. Polymer nano hydrophobic heavy anti-corrosion coating has excellent acid, alkali, salt spray corrosion resistance, anti-aging and other properties, solidified into a film at normal temperature, can form a strong sealing gas film between the matrix and the corrosive medium, well isolated the matrix and the external environment, to avoid the matrix being oxidized or corroded. At the same time, it is made of non-toxic and environmentally friendly raw materials, and does not produce toxic and harmful waste. In addition, the coating is sprayed to the substrate through a simple procedure, which can provide longer protection. Therefore, Titanian technology polymer nanohydrophobic heavy anti-corrosion coating can play an excellent and efficient protective role for facilities and equipment such as Marine engineering platforms and hulls in harsh Marine working environments, and truly achieve environmental friendliness.
