Inspection of Ballast Tank Plates and Welds Using SIMS

Sonomatic were engaged to work on a Spar platform in the Gulf of Mexico to inspect the bottom of the ballast tank. The client wanted to inspect the plates and welds.


Navigation on the spar was a challenge due to the unknown visibility at the location.

Sonomatic worked with the client to adapt the MagRover capability to have enhanced navigation and localisation by detecting features through the captured data, utilising a preloaded structural layout. Phased array and ToFD on the welds was carried out simultaneously, and database fusion was performed in real time for improved data management and confidence in the asset condition.


The data quality was much greater than originally expected and produced results beyond the expectation of the client, this allowed the client to reduce the scope and in turn, made cost savings.
