The application of carbon fiber in offshore engineering is mainly based on the properties of lightweight, high strength, and corrosion resistance. Replacing traditional steel building materials in tendons and structural parts, the carbon fiber rebar is free from corrosion and cost-saving in long-distance transportation. Carbon fiber materials in the offshore islands, docks, floating platforms, and lighthouse towers have been widely applied in many other countries.

Another application of carbon fiber in offshore engineering is the repair and reinforcement of submarine pipelines and columns. In the carbon fiber cloth, epoxy resin, and other high-strength and adhesive resins, the material is adhered to the repairable surface. It is thin and light, strong and durable, easy to process, and suitable for different shapes.

CFRT in Offshore Engineering

The use of carbon fiber composites in engineering maintenance began in the 1980s. Mitsubishi is the first to study the mechanical properties and engineering reinforcement performance of carbon fiber. The initial focus was on the reinforcement of concrete beams and then moved onto various civil engineering.

The excellent performance of carbon fiber composite makes it prospective in marine applications. Compared with its matured application in aerospace and some other fields, carbon fiber composites came a little later into the marine field, a possible consequence of the high cost in the material itself. With the development of maritime military and the exploitation of marine resources, it is an inevitable trend to promote the application of carbon fiber in the marine field.
