  • Maintenance optimisation for wind turbines. 

    Andrawus, Jesse A. (The Robert Gordon University The Robert Gordon University, School of Engineering, 2008-04)
    Wind is becoming an increasingly important source of energy for countries that ratify to reduce the emission of greenhouse gases and mitigate the effects of global warming. Investments in wind farms are affected by ...
  • Optimisation of offshore wind farm maintenance. 

    Sinha, Yashwant (Robert Gordon University Faculty of Design and Technology. School of Engineering., 2016-05)
    SINHA, Y. 2016. Optimisation of offshore wind farm maintenance. Robert Gordon University, PhD thesis.
    The installed capacity of European Offshore Wind Turbines (OWT) is likely to rise from the 2014 value of 7GW to 150GW in 2030. However maintenance of OWT is facing unprecedented challenges and cost 35% of lifetime costs. ...
  • Optimisation of wind turbine inspection intervals. 

    Andrawus, Jesse A.; Watson, John; Kishk, Mohammed; Gordon, Heather (Multi-Science Publishing. http://dx.doi.org/10.1260/030952408786411921, 2008-10)
    ANDRAWUS, J. A., WATSON, J., KISHK, M. and GORDON, H., 2008. Optimisation of wind turbine inspection intervals. Wind Engineering, 32 (5), pp. 477-490.
    The choice of correct inspection intervals poses a serious challenge to industries that utilise physical assets. Too short an interval increases operational cost and waste production time while too long an interval increases ...
  • The selection of a suitable maintenance strategy for wind turbines. 

    Andrawus, Jesse A.; Watson, John; Kishk, Mohammed; Adam, Allan (Multi-Science Publishing Co. Ltd. http://dx.doi.org/10.1260/030952406779994141, 2006-12)
    ANDRAWUS, J. A. et al., 2006. The selection of a suitable maintenance strategy for wind turbines. Wind Engineering, 30 (6), pp. 471-486
    Common maintenance strategies applied to wind turbines include ‘Time-Based’ which involves carrying out maintenance tasks at predetermined regular-intervals and ‘Failure- Based’ which entails using a wind turbine until ...
  • Significance of effective lubrication in mitigating system failures – a wind turbine gearbox case study. 

    Sinha, Yashwant; Steel, John A.; Andrawus, Jesse A.; Gibson, Karen (Multi-Science / Sage http://dx.doi.org/10.1260/0309-524x.38.4.441, 2015)
    SINHA, Y. and STEEL, J., 2015. Significance of effective lubrication in mitigating system failures – a wind turbine gearbox case study. Wind Engineering, Vol 38 (4), pp. 441-450.
    The effectiveness of lubrication in machines mainly depends on the physical and chemical properties of lubricating oil, like quantity, level of suspended particles, effect of external load/shear forces, temperature amongst ...
  • A SMART software package for maintenance optimisation of offshore wind turbines. 

    Sinha, Yashwant; Steel, John A.; Andrawus, Jesse A.; Gibson, Karen (Multi-Science / Sage http://dx.doi.org/10.1260/0309-524X.37.6.569, 2013)
    SINHA, Y., STEEL, J., ANDRAWUS, J. and GIBSON, K., 2013. A SMART software package for maintenance optimisation of offshore wind turbines. Wind Engineering, Vol 37 (6), pp. 569-577.
    Offshore Wind Turbine (OWT) maintenance costs in between 20 - 35% of the lifetime power generation cost. Many techniques and tools that are being developed to curtail this cost are challenged by the stochastic climatic ...
  • Wind Turbine Maintenance Optimisation: principles of quantitative maintenance optimisation 

    Andrawus, Jesse A.; Watson, John; Kishk, Mohammed (Multi-Science Publishing Co. Ltd. http://dx.doi.org/10.1260/030952407781494467, 2007-03)
    ANDRAWUS, J. A., WATSON, J. and KISHK, M., 2007. Wind turbine maintenance optimisation: principles of quantitative maintenance optimisation. Wind Engineering, 31 (2), pp. 101-110
    Maintenance optimisation is a crucial issue for industries that utilise physical assets due to its impact on costs, risks and performance. Current quantitative maintenance optimisation techniques include Modelling System ...
