  • The Modelling, Simulation and Control of a 50 kW Vertical Axis Wind Turbine 
    Bati, Akram F.; Brennan, Feargal P. (2012-09-13)
    This paper presents the modelling, Simulation and control of the APP 50 kW vertical axis wind turbine generating unit which is designed and built by Cranfield University, Department of Offshore, Process & Energy Engineering. ...
  • Multi-criteria assessment of offshore wind turbine support structures 
    Lozano Minguez, Estivaliz; Kolios, Athanasios J.; Brennan, Feargal P. (Elsevier Science B.V., Amsterdam., 2011-11-30)
    Wind power, especially offshore, is considered one of the most promising sources of ‘clean’ energy towards meeting the EU and UK targets for 2020 and 2050. Deployment of wind turbines in constantly increasing water depths ...
  • Non-stationary stochastic optimization of an oscillating water column 
    Jalon, Maria L.; Brennan, Feargal P. (World Academy of Science, Engineering and Technology, 2017-07-31)
    A non-stationary stochastic optimization methodology is applied to an OWC (oscillating water column) to find the design that maximizes the wave energy extraction. Different temporal cycles are considered to represent ...
  • A novel weight function for RMS stress intensity factor determination in surface cracks 
    Chahardehi, Amir Ebrahim; Brennan, Feargal P. (Elsevier, 2010-01)
    This paper discusses the problem of stress intensity factor determination in surface cracks. In particular, the concept of root mean square stress intensity factors (RMS SIF) is discussed for the general class of ...
  • A parametric whole life cost model for offshore wind farms 
    Shafiee, Mahmood; Brennan, Feargal P.; Armada Espinosa, Ines (Springer, 2016-03-14)
    Purpose Life cycle cost (LCC) considerations are of increasing importance to offshore wind farm operators and their insurers to undertake long-term profitable investments and to make electricity generation more ...
  • Reliability of floating foundation concepts for vertical axis wind turbines 
    Kolios, Athanasios J.; Collu, Maurizio; Brennan, Feargal P. (2010-12-31)
    Offshore wind turbines are developing at a rapid pace. By far the most common turbine configuration is the HAWT (Horizontal Axis Wind Turbine) and development of these machines is largely centered about drive train and ...
  • Report of Committee III.2: fatigue and fracture 
    Brennan, Feargal P. (Elsevier, 2003-12-31)
    COMMITTEE MANDATE Concern for crack initiation and growth under cyclic loading as well as unstable crack propagation and tearing in ship and offshore structures. Due attention shall be paid to practical application ...
  • Risk-based methods for sustainable energy system planning: a review 
    Ioannou, Anastasia; Angus, Andrew; Brennan, Feargal P. (Elsevier, 2017-03-02)
    The value of investments in renewable energy (RE) technologies has increased rapidly over the last decade as a result of political pressures to reduce carbon dioxide emissions and the policy incentives to increase the share ...
  • Stochastic prediction of offshore wind farm LCOE through an integrated cost model 
    Ioannou, Anastasia; Angus, Andrew; Brennan, Feargal P. (Elsevier, 2017-03-09)
    Common deterministic cost of energy models applied in offshore wind energy installations usually disregard the effect of uncertainty of key input variables – associated with OPEX, CAPEX, energy generation and other financial ...
  • Stress Monitoring of Civil and Mechanical Engineering Infrastructure 
    Brennan, Feargal P. (British Institute of Non-Destructive Testing, 2007-06)
    Structural Integrity Monitoring is a rapidly growing science and practice which promises in the future to measure and record every shudder and twitch within the lifetime of future structural components. Indeed, structures ...
  • Surface Crack Shape Evolution Modelling using an RMS SIF approach 
    Chahardehi, Amir Ebrahim; Brennan, Feargal P.; Han, S. K. (Elsevier, 2010)
    The majority of fatigue cracks in thick plate and tubular sections in structural components are two-dimensional surface cracks having significant propagation lives before becoming critical. The modelling of surface crack ...
  • Weld toe stress concentrations in multi-planar stiffened tubular KK joints 
    Woghiren, C. O.; Brennan, Feargal P. (Elsevier Science B.V., Amsterdam., 2009-01-31)
    This paper reports a parametric stress analysis of various configurations of rack plate stiffened multi-planar welded KK joints using the finite element method. The KK joint finds application in the leg structure of ...
