The purpose of the article is to determine the scope of regulations shaping the situation of workers employed at offshore wind farms. The authors believe that offshore wind farms, which are floating farms (not permanently connected to the seabed), should be recognized as ships, and therefore the provisions of the Act on Work at Sea should be applied to employees working on such farms. In addition, depending on where the offshore wind farm operates, this Act will apply in whole or only in part. The article presents the differences in the legal position of employees working on offshore wind farms in particular situations. In the opinion of the authors, the described differentiation of the situation of employees depending on the construction and location of the offshore wind farm is unjustified and constitutes a violation of the principle of equality of employees, and does not provide an adequate level of protection for the various categories of employees. Therefore, the authors present de lege ferenda postulates aiming at unifying the rules of employment of workers on offshore wind farms, while taking into account the specifics of employment on this type of facilities.
