  2. 1. On maintenance optimization for offshore wind farms

    Author : Francois Besnard; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle cost; optimization; maintenance; maintenance planning; Offshore wind energy; maintenance strategy; maintenance support organization; reliability;

    Abstract : The maintenance cost is known to be an important part of the levelized cost of energy generated by wind parks. Operational costs can be significantly reduced by optimizing decisions for maintenance strategies, maintenance support organization and maintenance planning. READ MORE

  4. 2. Reliability-based assessment procedures for existing concrete structures

    Author : Joakim Jeppsson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; reliability theory; service life; assessment; monitoring; hydraulic engineering; Civil engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : A feasibility study of reliability theory as a tool for the assessment of present safety and residual service life of damaged concrete structures has been performed in order to find a transparent methodology for the assessment procedure. It is concluded that the current guidelines are open to interpretation and that the variation in the results obtained regarding the structural safety is too great to be acceptable. READ MORE

  5. 3. On Optimal Maintenance Management for Wind Power Systems

    Author : Francois Besnard; Lina Bertling; Lars Gertmar; KTH; []
    Keywords : Wind Power; Maintenance; Reliability; Optimization;

    Abstract : Sound maintenance strategies and planning are of crucial importance for wind power systems, and especially for offshore locations. In the last decades, an increased awareness of the impact of human living on the environment has emerged in the world. READ MORE

  6. 4. Load and Risk Based Maintenance Management of Wind Turbines

    Author : Pramod Bangalore; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; wind energy.; supervisory control and data acquisition SCADA ; condition monitoring system CMS ; Artificial neural networks ANN ; maintenance strategy; maintenance planning; maintenance management; life cycle cost;

    Abstract : The cost of maintenance is a considerable part of the total life cycle cost in wind turbines, especially for offshore applications. Research has shown that some critical components account for most of the downtime in the wind turbines. READ MORE

  7. 5. Considering Engineering Change Management in Project Realisation : The Case of Offshore Platform Projects

    Author : Peter Sjögren; Monica Bellgran; Björn Fagerström; Tommy Olin; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Offshore wind converter platforms are complex installations that increase the competitiveness of offshore wind as an energy source. Prior research in the field of offshore platform project execution has focused on early project phases and planning as means to increase project reliability. READ MORE
