    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; vacuum technology; hydraulics; Mechanical engineering; a cost-effective vibration-based maintenance policy.; Integrated maintenance; Condition monitoring and control; Total Time on Test-plots; Vibration monitoring; effectiveness and accuracy; Failure causes and mechanisms; Maintenance quality; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; Commercial and industrial economics; Industriell ekonomi; Maintenance Technology; Failure analysis; Spectral analysis; Vibration-based maintenance policy; Maintenance cost-effectiveness; Selection of the most cost-effective maintenance strategy and policy; benchmarking; Total Quality Maintenance TQMain ; Cyclic improvement of maintenance experience; Terotechnology; Systemekonomi;

    Abstract : Modern machinery is expensive and therefore must run at high availability and effectiveness which cannot be achieved without an effective maintenance policy. Condition monitoring, (CM), techniques can be utilised to reduce or arrest the rate of deterioration of a component so increasing operating life. READ MORE

  2. 2. On maintenance optimization for offshore wind farms

    Author : Francois Besnard; Chalmers University of Technology; []
    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
