Summary: The rapid growth of offshore renewable energy has led to tremendous demands but also significant challenges in terms of high cost. To tackle this, advanced designs such as composite structures and flexible devices have been introduced. However, traditional structural dynamic analysis tools are unable to comprehensively analyze these new designs, especially their nonlinearity, hindering the development of offshore renewable technology. In order to address this issue, a new method is proposed to conduct nonlinear analysis by incorporating a variable Winkler-type viscoelastic foundation into geometrically exact beam theory. The advantages of this new method are validated through comparison with commercial tools and demonstrated through applications in wind turbines and wave energy converters.

Summary: In recent years, photovoltaic energy production has made significant progress and has been integrated into the grid through large-scale distributed systems. However, the intermittent nature of solar irradiance and the presence of photovoltaic failures can lead to fluctuations that compromise the stability of the electrical grid. This paper proposes a novel photovoltaic power smoothing method that combines moving averages and ramp rate with hybrid storage systems to reduce fluctuations. The method optimizes the number of charging/discharging cycles under PV failures. Experimental results show a reduction in the operation of supercapacitors compared to other power smoothing methods, and a photovoltaic failure detection method utilizing machine learning is also proposed.

Summary: Existing methods for optimizing wind array layouts typically use power or cost objectives and rarely consider reliability-based objectives. Component and system failure rates are dependent on wind conditions, influenced by array layout, and impact capital costs, operational costs, and power production. Computational efficient, reliability-based layout optimization methods have been developed to explore the relationship between component reliability and layout optimization.

Summary: The study shows that collocating offshore wind and wave power can reduce power variability, with varying effects at different locations. Significant reductions in variability are found on the US West Coast and UK North Sea, while minimal changes are observed on the US East Coast. The benefits of reduced variability depend on the specific wind-wave capacity mix in each region.

Summary: Wave energy, a renewable energy source with high potential, can be combined with end-of-life offshore stranded gas reservoirs for stabilizing the energy grid and increasing renewable energy penetration. Back-up systems are necessary for wave energy to ensure dispatching energy schedules. An innovative approach is developed to design offshore hybrid energy systems based on wave energy, optimizing gas to power back-up systems and operation strategies. The methodology considers various factors for evaluating the sustainability performance of the hybrid system and was tested in two offshore operating theaters. The results show similar design choices for the hybrid system, but the North Sea test-case had significantly higher annual energy production and lower levelized cost of energy compared to the Adriatic Sea test-site.
