Offshore wind farms: relevance› 13,9% of total EU electricity demand by 20301
Target Netherlands much more ambitious (Green Deal)› Cumulative investments 211,1 billion euros until 20302
› Annual reduction 315 Mt of CO2 emissions2
› 50.000 fte employment in The Netherlands by 20203
› Operations & maintenance (O&M) 25% of total cost1
› Service logistics typically 50% of O&M cost4
› 40% (O&M) cost decrease needed for profitable wind energy1
› Even for 2015 capacity (37.000MW5) and corresponding O&M cost, a 5% cost reduction amounts to 1 billion euros
› Smarter service logistics can help make this energy source truly sustainable

Challenges and sustainability goals addressed within 5 work packages
Challenges:• Lumpy service demand• Multi-material network
(spares, tools, consumables)• Coordination flows materials
and technicians (different transportation requirements)
• Coordination onshore and offshore flows
• Uncertainties (e.g. weather)• Coordination of return flows• Cooperation within and
across wind farms
Goals:• Improving availability• Reducing maintenance• Reducing waiting time• Reducing time spent offshore
(and onshore)• Reducing transportation

Work packages• Buffer and repair facilities design; location decisions; kitting locations; transshipment locations
WP 1: Onshore and offshore network design
• Failure prediction; opportunistic CBM; multiple resource planning; joint service and resource planning
WP 2: Planning of offshore service policies
• Vehicle assignment, routing, timing; storage; kit completion
WP 3: Coordination of sustainable service logistics
• Performance-based contracting, cooperation in diads and triads, multiple wind farms, trust
WP 4: Collaboration and governance aspects
• Robustness, simulation; cross-chain control, implementation
WP 5: Integrated logistics operations

Knowledge utilization› Societal and business relevance
Sustainable service logistics research contributes to targeted cost reductions (40% by 2020), reduced CO2 emissions, reduced risk for workers, economic growth
› Valorisation Continuous interaction with 12 external partners for
brainstorming, discussion, data gathering, model validation, implementation of solutions in business processes- Tool development and Implementation with partners ECN,
Oliveira, Eyewind › Dissemination
Dissemination through workshops, white papers, practical publications, lectures (e.g. Energy Academy Europe)- This will be done with the help of dissemination partners Dutch
Institute for World Class Maintenance and Energy Valley
