Decision support for maritime logistics challenges for offshore wind farms

Scientists at SINTEF Ocean (previously MARINTEK) have over several years, and in cooperation with other research institutions, academia and industry, developed models for optimization of the maritime logistics related to offshore wind farms. Some of these have been developed into decision support tools to aid stakeholders in the industry to select, and develop the most promising logistical resources. The tools are made based on mathematical formulations of the decision problems and use complex and efficient techniques from operations research to find optimal solutions according to the users' defined objective.

PROJECTS

The tools have been developed, and are continuously beeing improved through several research projects:

NOWITECH (2009 - 2017)
- Norwegian Research Centre for Offshore Wind Technology

An international research cooperation on offshore wind technology, co-financed by the Research Council of Norway, industry and research partners.
Objective: Precompetitive research laying a foundation for industrial value creation and cost-effective offshore wind farms. Emphasis is on "deep-sea" (+30 m) including bottom-fixed and floating wind turbines.

Key research areas:

  • Integrated numerical design tools for novel offshore wind energy concepts.
  • Energy conversion systems using new materials for blades and generators.
  • Novel substructures (bottom-fixed and floaters) for offshore wind turbines.
  • Grid connection and system integration of large offshore wind farms.
  • Operation and maintenance strategies and technologies.
  • Assessment of novel concepts by numerical tools and physical experiments.

FAROFF (2012 - 2013)
- Far offshore operation and maintenance vessel concept development and optimization

Innovation project for the industry co-financed by the Research Council of Norway. 
Partners: Statkraft, Statoil, Fred. Olsen Windcarrier, Offshore Kinetics, Odfjell Wind, SINTEF Ocean/MARINTEK, SINTEF Energy Research

Activities:

  • Development and evaluation of far-offshore O&M vessel concepts (SINTEF Ocean/MARINTEK)
  • Development of life-cycle O&M simulation model for vessel concept decision support (NOWIcob, SINTEF Energy Research)
  • Development of O&M vessel fleet size and mix optimization model (SINTEF Ocean/MARINTEK)

LEANWIND (2013 - 2017)
- Logistic Efficiencies And Naval architecture for Wind Installations with Novel Developments

Funded under the Seventh Framework Programme of the European Union.
Objective: Provide cost reductions across the offshore wind farm lifecycle and supply chain.

Key research areas:

  • Construction, deployment and decommissioning
  • Novel vessels and equipment
  • Operation and maintenance strategies
  • Integrated logistics
  • Economic and market assessments

INSTALLER (2018 - 2020)
- Floating installation concept for offshore wind developments

Innovation project for the industry co-financed by the Research Council of Norway.
Partners: National Oilwell Varco, Statoil, Ulstein, Fred. Olsen Windcarrier, SINTEF Ocean

Project goal: To develop a flexible and cost-efficient solution for large offshore wind turbines, located at sea-depths exceeding current capabilities of jack-up vessels.

In this project, the LIVO-tool developed in the LEANWIND project will be further developed and used for value chain and cost-benefit analysis.
