SPOWTT focuses on offshore wind farm transits in a bid to improve safety & productivity


A consortium of European offshore wind and maritime industry players has initiated the project ‘improving Safety and Productivity of Offshore Wind Technician Transit’ (SPOWTT), which aims to widen the workable weather window for Crew Transfer Vessels (CTV) and to improve the productivity of technicians performing service activities on offshore wind turbines.


The project consortium consists of BMO Offshore, Energy research Centre of the Netherlands (ECN), Offshore Renewable Energy Catapult (ORE Catapult), Siemens, Specialist Marine Consultants, the University of Hull and MARIN.


Measurements on board CTVs and of the surrounding environment will be combined with psychological and physiological methods to monitor the well-being of the technicians as they transit in different sea conditions. The relationship between the environment, ship motions and technician well-being will result in a tool that will support the CTV operators in making decisions about whether it is safe to launch, or to launch but only with certain control measures in place.

Optimised weather window Optimising how CTVs make use of the ‘weather window’ to deliver technicians will improve productivity and lead to increased turbine


availability. When combined, it is estimated that this innovation will lead to a 0.7% reduction in the levelised cost of electricity; equivalent to additional revenue of more than €1.2m a year for a 500MW wind farm. To make uptake as rapid as ossible the ‘model’ that is created will be open access and will be promoted for use throughout Europe across the existing and future CTV fleet.


This project has received funding from the European Union’s Horizon 2020 research and innovation programme and the Dutch Ministry of Economic Affairs via its “TKI Wind op Zee” (Topsector Energie) initiative. SPOWTT started in 2016 and will run until 2020.
