Our team of highly qualified experts with a strong drive for innovation and a healthy dose of conservatism developed the fit for purpose semi-submersible crane vessel OWL-010.
The vessel combines 150 meters of hook height with high hook position precision by 3D motion compensation. The lower daily rate and 50% faster turnaround time of the OWL-010 both contribute to the common goal of reducing the offshore renewable energy LCOE.
By sailing under the Dutch flag and DNV GL class, the OWL-010 meets the highest levels of safety and she is designed and built to the highest standards with a green profile.
The vessel is the ideal platform for wind turbine related services because of the following characteristics
- Able to serve any wind turbine, anywhere.
- Lower day rate and faster turnaround times compared to other cranes with same hook height.
- State of the art 3D motion compensated crane provides great hook accuracy.
- Unrestricted by a maximum operational water depth or by soil conditions.
- Longer working seasons and improved fuel efficiency.
- Benchmark safety and comfort levels.
- Capable of operating on transit draft, enabling to access and operations in shallow waters + increasing hook height.
- Unit is designed and certified for worldwide unrestricted operation.
- Planned delivery ex-yard mid 2022.
Workability analysis performed
- Defined typical vessel operational limits for various operations.
- Frequency domain motion analysis using 3D Diffraction.
- Spectral motion analysis.
Workability based on wave scatters for locations
- North Sea German Bight: Dolwin 3.
- North Sea Dogger Banks.
For both these regions, indicative workability is approximately
- 100% in summer.
- Over 75% in winter.
It is assumed that the vessel is free to weather vane and can always use the best heading for the lift operation.
At request, OWL Heavy Lift can provide details of the above mentioned and/or revise workability of the OWL-010 for specific geographic site locations.
