In offshore aquaculture, polyester felt is revolutionizing fish farming. Traditional fish cages are often vulnerable to damage from strong ocean currents, marine organisms, and harsh weather conditions. Polyester felt – reinforced fish cages offer enhanced strength and durability. The felt’s high – tensile – strength fibers can withstand the forces exerted by waves and currents, reducing the risk of cage breakage. Additionally, polyester felt’s resistance to corrosion from saltwater and marine organisms ensures a longer lifespan for the cages. This not only protects the fish within but also reduces the frequency of cage replacement, making aquaculture more cost – effective and environmentally friendly. Moreover, polyester felt can be used to create filters within the fish cages, helping to maintain water quality by removing waste and excess nutrients, promoting a healthier environment for the fish.​

For offshore oil and gas exploration, polyester felt plays a vital role in pipeline protection. Submarine pipelines are exposed to extreme conditions, including high pressure, corrosive seawater, and potential damage from marine activities. Polyester felt – based insulation and protective coatings can be applied to these pipelines. The insulation helps maintain the temperature of the transported oil and gas, preventing wax formation and reducing energy consumption. The protective coating, with its excellent chemical resistance, shields the pipeline from seawater corrosion and mechanical damage. This significantly extends the service life of the pipelines, ensuring a stable and reliable supply of energy resources from offshore fields.​

In marine construction projects, such as the building of offshore wind farms and artificial reefs, polyester felt is also being utilized. For offshore wind farms, polyester felt can be used in the construction of foundations and platforms. Its high – strength and durability contribute to the stability of these structures in the harsh marine environment. In the creation of artificial reefs, polyester felt can be incorporated into the materials used. It provides a suitable surface for marine organisms to attach and grow, promoting the development of marine ecosystems around the reefs. This not only enhances biodiversity but also helps protect coastal areas from erosion by dissipating wave energy.​

As the world increasingly turns to the oceans for resources, the importance of polyester felt in marine applications will continue to grow. With ongoing research and development, new and improved polyester felt – based products are expected to emerge, further enhancing the efficiency and sustainability of marine resource exploitation while minimizing the environmental impact on the delicate marine ecosystem.
