About this Research Topic
The increasing demand for availability and reliability of energy supply worldwide, in combination with improved environmental standards, make the optimum design and safe operation of energy projects a vital issue with significant safety and economic requirements. Although most of the energy projects are located onshore, during the last decades various energy projects have been designed and constructed offshore, while many more are expected to be constructed in the near future. Usually, the energy projects (such as oil and gas tanks, oil refineries, offshore platforms and wind turbines) have relatively small dimensions, but in some cases high-pressure gas pipelines or electric cables may cross extensive areas on the land and/or the sea and can be exposed to various hazards and geohazards as well as a variety of topographical/bathymetrical and geological conditions.
Since most energy projects are complicated systems / structures, the best possible design of such projects requires mainly structural, mechanical and geotechnical engineering skills, while earthquake engineering is also necessary in the case of energy projects located in areas characterized by moderate to high seismicity. Moreover, current norms, guidelines or standards, mainly proposed for ordinary and regular structures, may be insufficient or inappropriate to ensure the desired level of performance and safety during the operation of such complex systems.
Hence, it is evident that during the design phase of an energy project all aforementioned disciplines are based on sophisticated and advanced numerical simulations in order to: (a) take realistically into account all potential loads under static and dynamic conditions, (b) simulate the (nonlinear) behavior of the various materials, including the behavior of the soil(s), and (c) the anticipated interactions between the structure(s) and the soil(s). As expected, the "degree of sophistication" of the numerical simulations depends on the importance/criticality of the energy project and the available resources (input data, software, engineers’ skills and experience, cost, etc). Therefore, this collection of papers will consist a forum for presenting state-of-the-art research on advanced computational methodologies and their applications on onshore and offshore energy infrastructure projects. It will serve as a valuable reference and will be extremely helpful to all people involved in this field: researchers, professional engineers and decision-makers.
