Marine Operations and Logistics
Developing methods and tools for efficient and safe marine operations and logistic planning for installation and maintenance of offshore wind farms.
Work Package 2 is led by Henning Braaten from SINTEF Ocean and Svein Sævik from NTNU. Its focus areas are installation and replacement, vessels and access solutions and offshore wind farm logistics.
Anticipated results:
- Digital twin for more efficient marine operations
- Safe and robust access solutions
- Optimal logistic planning for marine O&M
Hypothesis
Developing efficient and innovative installation/access methods and optimised maintenance strategies is the key to enable massive deployment of future offshore wind farms and to reduce OPEX.
Methodology and research tasks
Installation and replacement operations.
Blade installation/replacement and seabed preparation methods.
Service Operation Vessel (SOV) for offshore wind turbines
Advanced simulations for vessel design optimisation and onboard decision support system (ODSS) for walk-to-work (W2W) operations.
Offshore wind farm (WF) logistics
Installation and decommissioning logistics, predictive maintenance logistics and industrialisation of supply chain.
