Polymer Coupons

To maintain the integrity of the flexible riser it is important to monitor the condition of the polymer in the pressure barrier sheath. The Cosasco® Polymer Monitoring System is used for determining the potential breakdown or ageing of the polymer material under operating conditions.  The Cosasco® Polymer Monitoring System consists of a polymer coupon holder and solid plug assembly installed in a standard 2” Access Fitting that would normally be located in a topside rigid pipe, downstream of the riser end connection.
