Quality defects of underwater assets in offshore wind power and the detecting methods
The cost of underwater assets in offshore wind farms is relatively low compared with the total cost of offshore wind power projects,yet the quality of these assets is vital for safe and stable operation of the offshore wind farms.The quality issues that can arise with wind turbines,underwater steel structures and foundations of offshore substations,and submarine cables during the construction and operation and maintenance phases are analyzed.Based on cases from practical offshore wind power generation projects,the inspection requirements and methods stipulated by relevant standards are evaluated,and comprehensive and effective underwater inspection methods for various types of quality defects are put forward.These methods have been verified in real cases,forming industry standards and specifications,which provides significant technical guidance and reference value for quality control and operational maintenance of underwater assets in offshore wind farms.
