  2. 31. 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

  5. 33. Wave Loads on Offshore Wind Power Plants

    Author : Jenny Trumars; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ocean engineering; shallow water; fatigue; Non-linear waves; wave load; wind energy converter; perturbation theory;

    Abstract : The thesis gives a short introduction to waves and discusses the problem with non-linear waves in shallow water and how they effect an offshore wind energy converter. The focus is on the realisation of non-linear waves in the time domain from short-term statistics in the form of a variance density spectrum of the wave elevation. READ MORE

  6. 34. Analysis and improvement of risk assessment methodology for offshore energy installations : Aspects of environmental impact assessment and as-built subsea cable verification

    Author : Andreas Olsson; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DST; Decision Support Tools; subsea cables; statistical method; environmental risk; risk of accidents; Systemteknik; Systems Engineering;

    Abstract : In the expansion of offshore sustainable energy systems, there is growing pressure on the environment and permit processes and the accumulation results in much higher total risk for accidents of future assets. Anticipating the problems at the design stage and improving verification is likely to increase energy development and reduce costs. READ MORE

  7. 35. Nonlinear finite element simulations of ice forces on offshore structures

    Author : Björnar Sand; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The present investigation has been devoted to the development of nonlinear finite element simulations by means of obtaining ice forces on structures. The effects of material nonlinearities and friction between ice and structure are taken into account. READ MORE
