Full management of underwater sacrificial anode installation projects is offered to clients requiring either new anode installation, or depleted anode replacement. This operation requires experienced underwater welder divers that have the skill and knowledge to ensure that through correct installation and high-performance underwater welding, any submerged metal gains maximum cathodic protection.
A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead of the protected metal.
Regular submerged structure types such as quayside walls, piers, jettys and vessels, all benefit from years of protection through sacrificial anodes.
Sacrificial anodes usually have a maximum life span of around 20 years, before replacement is required dependant on the type of metal and the environment that they are installed within.
Quite often Anode inspections will be carried out at planned periodic stages. Depletion percentages can be gauged and recorded, allowing for the depletion levels to be monitored. This information can also be used for future financial planning and calculating approximate time scales for replacement purposes. UKDC can supply anode inspection services, with monitoring. HD Video evidence of depletion, accompanied with written reports are supplied to clients for record and comparison purposes.
