Offshore facilities are covered with marine life, such as algae, mussels, sponges, barnacles and bryozoa. What are the disadvantages? Is there any way to solve this problem?

Marine life (algae, mussels, sponges, barnacles and bryozoa, etc. ) attached to the surface of the hull and offshore facilities, which seriously affects the normal operation and increases the operating cost. It has been proved that biological fouling can slow down ships by as much as 40%. Without the effective protection of antifouling coatings, the industry will spend an additional $35 billion on fuel and emit 400 million tons of carbon dioxide every year. On the fixed facilities of the ocean, the attachment of marine life causes pipeline blockage, anoxia of mariculture, increased load of facilities and accelerated corrosion. It has become a challenging problem in the industry to effectively control the growth of marine life and keep the outer surface of marine facilities smooth and clean so as to minimize the resistance.

Now there is a kind of coating: bionic self-cleaning antifouling coating material, which can ensure smooth facilities, low source ridge friction, ensure normal operation of facilities and significantly reduce fuel and CO2 emissions. Bionic self-cleaning antifouling coatings abandon the traditional technical route of releasing antifouling agents into the sea, and do not add heavy metal biocides such as TBT, DDT, mercury and copper. Adopting the most advanced drag-reducing nano bionic technology, combined with new resin, environmental protection antifouling agent and silicone antifouling desorption technology (FRC), it is a good antifouling coating for friends of marine ecology. Long-term anti-pollution: the effective anti-pollution time is as long as 60 months; Excellent tear resistance: it is 10 times higher than silicone FRC antifouling paint; Ultra-high flexibility: resistant to 180 bending without cracking paint film; Excellent wear resistance: resistance to wire brush and fishing net machine cleaning; Good adhesion: on metal, plastic and cement substrates, the adhesion is more than 5 MPa and the VOC is low: the volume solid content is more than 80%; Good construction performance: single channel can reach 250μm without sagging.
