Pipeline cathodic protection (CP) test stations
Acteon's cathodic protection CP test stations are the most cost-effective method for gathering accurate pipeline readings. There are options for buried and unburied subsea pipelines.
The most common method of evaluating the cathodic protection of subsea pipelines is the three-electrode survey method, which has not proved very reliable in practice.
We developed a far more accurate and cost-effective survey method with its CP test stations. On unburied pipelines, RetroClamps™ fitted with special stab plates are attached around every 10 Km, allowing an ROV to take a stab reading of the pipeline’s real potential and not that of the anode’s. The clamp is electrically connected to the pipeline, and a freely-corroding “coupon” on it draws protection from the CP system. Stabbing the coupon yields an accurate potential reading without damaging the pipeline’s coating.
For buried pipelines, our RetroMat™ is used as a test station. The RetroMat, fitted with stab plates and coupons, is laid on the seabed and is electrically attached to the buried pipeline using a RetroClamp. CP readings can be easily taken from the mat’s stab surface by the ROV’s probe, resulting in far more accurate readings than the three-electrode method can provide.
