Importance of HSE in Wind Farm Operations

Offshore wind farm operations are complex and demanding, requiring a high level of safety and sustainability to operate effectively. While responsible for ensuring that these wind farms operate that way, the HSE department also plays a critical role in developing and implementing safety procedures and protocols, training workers, monitoring and evaluating offshore wind farm operations, emergency response planning and execution, and promoting a culture of safety.

The Global Offshore Wind Health Organization Incident Report highlights (source) that in 2021 alone, there were 780 reported incidents resulting in 106 recordable injuries, fortunately with no fatalities, but 72 lost or restricted workday ones, and 34 medical treatment accidents.

The number of hours worked increased by a staggering 28% compared to the previous year, mainly due to the construction of offshore wind farms, which saw an increase from 14.9 million to 19.1 million hours. As more offshore wind farms become operational, there is a steady and progressive increase in the hours worked.

HSE's daily life in wind farm operations

Developing and implementing safety procedures and protocols is one of the HSE's fundamental roles. The department ensures that all aspects of offshore wind farm operations, from construction to maintenance and decommissioning, are covered by comprehensive safety procedures and protocols.

It also ensures that all workers are trained in safety procedures and protocols and have access to the necessary equipment and tools to work safely. Regular training and refresher courses are conducted to ensure that workers remain up-to-date, thereby maintaining safety standards and reducing the risk of accidents or incidents.

Monitoring and evaluating offshore wind farm operations is another crucial role. Regular inspections and audits are conducted to identify potential hazards and risks, recommend corrective actions, and ensure that offshore wind farm operations comply with relevant health, safety, and environmental regulations. HSE's work in this area ensures that safety and sustainability are at the forefront of offshore wind farm operations, reducing the negative impact on the environment and ensuring the safety of workers and stakeholders.

The HSE department is also responsible for emergency response planning and execution by working closely with other stakeholders, including emergency services, to develop and implement emergency response plans and procedures that minimize the impact of any accidents or incidents that may occur (read more about RFID mustering).

The department also ensures that workers are trained in emergency response procedures and that the necessary equipment and resources are available to respond quickly and effectively to emergencies, thereby minimizing the risk of loss of life and damage to the environment.
Promoting a culture of safety in offshore wind farm operations is the final key role of the HSE by developing and implementing safety campaigns and initiatives to raise awareness and promote a culture of safety among workers.

In addition, the department works with stakeholders to create and implement sustainability initiatives that help to minimize the impact of offshore wind farm operations on the environment. HSE's work in this area helps to ensure that offshore wind farm operations remain sustainable and safe for all stakeholders involved, enhancing the industry's reputation and promoting its growth.

Despite efforts to improve safety in wind turbine nacelles, the number of incidents and injuries remains a concern. In 2021, the nacelle saw the highest number of recorded incidents and injuries, totalling to 91 - a 16% increase from the previous year and the third-highest on record.

However, there is some good news, as a result of improved turbine design and maintenance practices that minimize hazards and standardized procedures within the turbine, the number of recordable injuries has significantly reduced to 9, the lowest ever recorded.

Unfortunately, lifting operations continue to be the main cause of most incidents, with a 53% increase from the previous year. This highlights the need for better training and safety protocols around those operations.

Furthermore, 30 high-potential incidents occurred within the nacelle, 88% more than in 2020, and the third-highest on record. These high-potential incidents serve as a warning sign that more needs to be done to ensure the safety of workers in this specific part of the turbine.

Although reducing recordable injuries is a step in the right direction, it is crucial to prioritize safety in the nacelle. The wind industry must remain vigilant in identifying and mitigating hazards to prevent incidents and injuries in the future. By implementing effective safety measures and best practices, the industry can work together to reduce incidents and ensure the safety of all workers.



As offshore wind farms become more prevalent, Crew Transfer Vessels (CTV) have become an essential mode of transportation for workers. However, the increasing number of incidents involving CTVs has become a significant concern for the industry.

With 85 incidents reported in 2021, an 8% increase from the previous year, those vessels have become a focal point for safety improvement efforts. However, the high potential incidents, matching last year's number and setting a new record low, were still a cause for alarm, with 18 incidents reported.

Most incidents occurred during transit, with 32% being high potential incidents, while nine incidents involved lifting, representing a significant increase of 125% compared to the previous year, with 44% of these incidents being high potential. These incidents can have a wide-reaching impact on many individuals, considering the crucial role of CTVs in transferring personnel to and from wind farms. Therefore, there is a need to improve safety onboard.

It is crucial to implement measures that ensure the safety of workers on the transfer vessels, as it is the industry's responsibility to provide a safe working environment. The offshore wind industry is continually evolving, and safety must remain a top priority to guarantee the industry's success.

By improving safety onboard CTVs, the industry can ensure that workers are protected and their well-being is safeguarded.
