We have estimated the costs of a subsea riser system, for a typical deep-water project; and the potential cost-reduction that can be achieved by using ThermoPlastic Composite Pipe instead (e.g., Airborne, Magma). Savings should be around c45%, or c$20M/riser. Our data-file also includes the order-history to-date for TCP: by project, operator, and geography (below).
