Within a few weeks in a 2012 cathodic protection (CP) trial for monopiled windturbine structures in the North Sea, the seawater pH inside the monopile dropped from 8 to 5 and toxic gas (H2S and CO) alarms were energised. This paper explains why.
Long-term (>1.5 years) field testing of reference electrodes and anodes are carried out on port facilities in Kozmino (marine conditions) and in Ural region (in soils). Experimental procedures and some observations made in course of the testing.
Seawater pH inside an offshore wind turbine monopole had changed from pH 8 to less than pH 5. And toxic gas alarms were energised. This paper discusses a theory why the pHdropped and solutions to overcome the low pH with the use of aluminium anodes.
Literature on cathodic protection (CP) in the ocean at depths greater than 300 m (1,000 ft). Reports extensively on deep water field test results and operating experiences.
This NACE International standard has been prepared to provide users and manufacturers of embeddable anodes with a test method for evaluating the anode material to an expected lifetime criterion. Historical Document 1994
