Design Issues With Subsea And Downhole Components
For structures below the water line and in the borehole, composites add to their list of benefits the key characteristic of design flexibility, because composite materials can be tailored to meet specific challenges. For example, composites can add buoyancy to low-pressure steel air cans on a spar platform’s r

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

Studies Support Viability Of Composites
Numerous studies have compared the performance and cost of steel and composite tendons. Conoco, Norske Conoco A/S (NCAS) and KOP headed several projects to qualify composite TLP tethers prior to launching a full sea test. In a recent study, they compared steel and composite TLP systems in water depths up to 9,
