Lightweight Tomographic Monitoring of Pipe Wall Thickness

Product Number: MECC23-19896-SG

Publication Date: 2023

While corrosion and erosion in subsea pipes remains a significant concern, instrumentation has been developed to provide detailed mapping of wall thickness loss. In the mid-2000s the Corrosion-Erosion Monitor was introduced, which utilizes guided ultrasonic waves (GUW) to monitor mean wall thickness loss between non-intrusive ultrasound transducers installed permanently on pipe sections with typical length 0.7 m–1 m [1, 2, 3, 4]. The tomography software package was developed in the 2010s [5, 6, 7, 8] to produce two-dimensional wall thickness maps from the GUW monitoring data.

One of the key factors affecting ship performance, particularly fuel consumption and associated GHG (Green House Gas) emissions, is the degree of biofouling on the immersed hull and propeller(s). Rates of biofouling accumulation vary considerably, depending on the suitability, age and physical condition of the coating system(s) applied to the hull, the voyaging, anchoring and lay up patterns of the ship, and the geographical regions where these take place.
