Manufacturing Methods
Composite parts can be made in a controlled factory environment and delivered to the site as finished pipe, beams or grating, or fiber and resin can be combined on site to make or repair structures. Regardless of the fabrication method and its location, a quality composite requires that the reinforcement be co

A variety of resins can be used for offshore applications, depending on the requirements for the final product. General-purpose polyester offers a low-cost option that provides greater corrosion resistance than steel. Isophthalic polyester provides somewhat better corrosion resistance, while vinyl ester is pre

Petrobras Pioneers Topside Composites
Petrobras (Rio de Janeiro, Brazil) was the first major oil company to experiment with molded gratings in the 1980s, though these early products proved unsatisfactory due to wide variations in mechanical properties. However, advances in pultrusion and filament winding technology coupled with the availability of

The Composite Carbon Cable system developed by Doris Engineering, IFP, Soficar and Freyssinet is based on a different design. Their concept is to assemble a tether from uniformly sized strands or “modules” made up of parallel rods. Each module is hexagonally shaped, allowing any number of modules (strands) to
