Description

technical field [0001] The invention relates to a cathodic protection simulation experiment device and method for an ocean platform, which is mainly used for a platform cathodic protection effect evaluation experiment and belongs to the field of electrochemistry. Background technique [0002] The offshore platform is the main equipment for offshore oil and gas exploitation. It is mainly composed of steel structures and located in the vast ocean. The structure is complex, the construction is difficult, and the investment is huge. Compared with land-based oil extraction equipment, the environment it is in is very harsh. The platform is exposed to seawater erosion, wind and waves, currents, sea ice and a series of factors during operation, which is a great test for the main steel structure of the offshore platform. . Corrosion of the platform material is so severe that cathodic protection must be employed. However, due to the difficulty of underwater construction, cathodic pr...

Problems solved by technology

However, due to the difficulty of underwater construction, cathodic protection facilities are usually determined by software simulation to determine the protection scheme, and then directly installed in the platform construction process, which is quite different from the actual working conditions. Once there are problems such as insufficient protection potential and premature failure, Costly repairs required
