N2 - This study investigated productivity in an offshore wind project to understand the distribution of their value-adding and non-value-adding hours. A comprehensive literature review presented results on productivity in regular mega-projects, revealing a limited knowledge of offshore wind projects. From the first quarter of 2019 to the early second quarter of 2020, 62,447 realized activities, equaling 213,786 h, were sampled from a wind farm development project in the British sector of the North Sea. This data was then analyzed and presented through a descriptive statistic. The results showed a distribution of 21.21% value-adding (VA) and 50.09% non-value-adding (NVA) hours. With 20.9% of the total hours, the weather is the dominant cause of waiting time, followed by vessels and previous tasks. The findings further show the disruptions of the COVID-19 pandemic and its effects on productivity. It supports and expands on existing knowledge of causes for waiting time in offshore wind projects, ultimately providing the industry with an understanding of areas that need development to enhance productivity. The paper contributes to current knowledge by providing an understanding of productivity in offshore wind projects.
