As more and more offshore structures enter, or have exceeded their design life, many continue to be kept in service due to operational necessity.
Cost savings can be gained through early intervention, which will reduce extensive anode replacement, and minimise vessel time and, in many cases, diver intervention. The benefits are particularly apparent if action is taken before the original anodes are fully depleted and depolarisation begins.
ISES offers detailed assessments that, when combined with cathodic protection surveys and field gradient measurements, provide a clear indication of the effectiveness of the existing CP systems and support the planning and optimisation of future anode retrofit programmes, thereby helping to extend the operational life of offshore assets efficiently and cost effectively.
