Importance of a Robust Commissioning Strategy for Offshore Wind Farms

Commissioning is a critical phase in the development of offshore wind farms, marking the transition from construction to operation. A well-defined commissioning strategy is essential to ensure the seamless integration of various components, validate their functionality, and ultimately optimize the performance and reliability of the entire offshore wind farm.

Boslan, an engineering and consultancy company with more than 20 years of experience in the energy industry, understands the significance of having a comprehensive commissioning strategy that outlines the key components it should encompass and complies with the regulatory considerations. In this sense, after more than a decade of experience providing onshore wind services, Boslan has developed a Corporate Commissioning Manual that serves as a foundation for devising the strategy to be applied in any offshore wind project. Boslan can adapt this Commissioning Manual to the particularities of the any project and it is a living document that continues to improve with the experiences and lessons learned from the commissioning services provided by Boslan.

 A commissioning strategy provides a systematic and organized approach to integrating the diverse components of an offshore wind farm. This includes turbines, substructures, electrical systems, and control systems. The strategy outlines a step-by-step plan for connecting and testing each component to ensure they function cohesively as a unified system.

Additionally, a well-thought-out commissioning strategy helps identify potential risks and challenges before they escalate. It allows for thorough testing and validation of critical systems, reducing the likelihood of operational issues or failures during the operational phase. By addressing issues early in the commissioning process, developers can save both time and resources. A robust strategy includes procedures for performance testing, calibration, and optimization, ensuring that the turbines operate at their maximum efficiency. This not only enhances energy production but also contributes to the economic viability of the project.

Boslan develops commissioning strategies through close collaboration between project stakeholders and Boslan’s Services Managers. Individuals like Paul Carney, with extensive experience in developing such strategies and their subsequent implementation, play a crucial role. Paul Carney holds multiple certifications, the highest authorization level for HV Switching, and has experience in numerous projects such as Wikinger (Iberdrola), Burbo Bank (Orsted), and Borssele (Orsted).

The key components that a Commissioning Strategy should have are:

  1. Pre-Commissioning Inspection:
    Before the commissioning phase begins, a thorough pre-commissioning inspection should be conducted. This involves verifying that all components are installed correctly, assessing the quality of construction, and ensuring compliance with design specifications and regulations.
  2. Functional Testing:
    The strategy should outline detailed procedures for functional testing of each component. This includes testing the turbines’ power generation capabilities, validating electrical systems, and checking the communication between turbines and the central control system.
  3. Grid Connection Testing:
    As grid connection is a critical aspect of offshore wind farms, the commissioning strategy should include comprehensive testing of the interconnection with the electrical grid. This ensures that the wind farm can reliably supply electricity to the grid and adhere to grid code requirements.
  4. Safety Systems Verification:
    Safety is paramount in offshore environments. The commissioning strategy must encompass rigorous testing of safety systems, including emergency shutdown procedures, fire detection and suppression, and personnel evacuation protocols.

In addition to this, an appropriate strategy must comply with the relevant regulations. Offshore wind farms must adhere to international standards such as IEC 61400 for wind turbine design and IEC 62282 for electrical systems. The commissioning strategy should align with these standards to ensure compliance and facilitate certification processes.

Regulatory compliance extends beyond technical aspects to encompass environmental and permitting regulations. The commissioning strategy should include procedures for monitoring and mitigating potential environmental impacts, such as noise levels and wildlife interactions, to meet regulatory requirements.

Additionally, offshore wind farms must comply with grid codes stipulated by the relevant transmission system operator (TSO). The commissioning strategy should address grid connection requirements and ensure that the wind farm meets the specified technical standards.

In conclusion, a well-defined commissioning strategy is indispensable for the successful deployment of offshore wind farms. By systematically addressing integration, risk mitigation, and performance optimization, developers can ensure that the wind farm operates efficiently and reliably. Moreover, compliance with international standards and regulatory requirements is paramount, emphasizing the need for a comprehensive commissioning strategy that covers technical, environmental, and safety considerations. The implementation of such a strategy not only supports the long-term success of the wind farm but also contributes to the sustainable growth of the offshore wind industry.
