Case study

Independent technical review of a wind turbine transformer platform cathodic protection (CP) system

We helped our client identify and rectify shortfalls in its proposed cathodic protection (CP) design, and worked with DNV to rectify an error spotted in its standard.

We undertook an independent technical review of the proposed cathodic protection (CP) system for a subsea wind farm transformer platform.

Using a combination of hand calculations and modelling we identified a number of shortfalls in the original design and recommended improvements in the design. This allowed changes to be made onshore, avoiding the costs and difficulties of remedial offshore work should the shortfalls have only been identified once in operation.

During this work we also identified an error in classification society and certification body DNV’s standard, and worked with it to agree the correct approach.
