Elsyca was approached by Exmar Offshore Company, based in Houston, to evaluate and redesign the cathodic protection installation for the Opti-Ex production semi-submersible oil rig. With Elsyca’s technology, reliability of the corrosion protection over the complete structure is assured, leading to substantial cost reductions over the service life of the system. The technology mitigates the risk of not meeting the design goals and enables future management of assets to be lanned effectively.
