Structural Testing of Tidal Turbine Blades
Structural testing of tidal turbine blades is vital due to several reasons. Firstly, it allows for the optimization of blade performance, ensuring efficient energy conversion and maximizing power output. Secondly, it ensures the reliability and safety of the blades, enabling them to withstand harsh marine conditions and reducing the risk of failure or damage. Thirdly, structural testing helps assess the durability of the blades, determining their fatigue life and enabling effective maintenance strategies. Additionally, it aids in designing cost-effective solutions by evaluating materials, manufacturing techniques, and configurations. Finally, structural testing facilitates regulatory compliance, ensuring that blades meet the necessary standards and certifications for deployment in tidal energy projects. Overall, structural testing plays a crucial role in enhancing performance, safety, durability, cost-effectiveness, and regulatory compliance of tidal turbine blades.

Shipping Decarbonization
Decarbonization in the shipping industry could be achieved through technical and operational strategies such as Energy Saving Devices (ESDs) to reduce the fuel consumption of new and existing ships. According to the makers, ESDs can optimize fuel efficiency by up to 15%. Researchers review the current literature on stern hydrodynamic ESDs, which are mainly used on typical merchant vessels, i.e., bulkers, tankers, and carriers.

Ship Fouling Cleaning
Ship fouling has significant adverse effects on vessel performance and environmental sustainability. Therefore, it is imperative to regularly clean ship hulls to reduce the adverse impacts of biofouling. A bi-level programming model to simultaneously optimize cleaning equipment deployment by cleaning service providers in the upper level and cleaning decisions by shipping companies in the lower level is developed to achieve the goal.

Shape-Informed Dimensional Reduction in Airfoil/Hydrofoil Modeling Approachs
Parametric models have been widely used in pertinent literature for reconstructing, modifying and representing a wide range of airfoil and/or hydrofoil profile geometries. Design spaces corresponding to these models can be exploited for modeling and profile-shape optimization under various performance criteria. Accuracy requirements, along with the need for modeling local features, often lead to high-dimensional design spaces that hinder the process of shape optimization and design through analysis.

Semantic Modeling, Simulation and Cybersecurity in the IoUT
As maritime and military missions become more and more complex and multi-factorial over the years, there has been a high interest in the research and development of (autonomous) unmanned underwater vehicles (UUVs). Latest efforts concern the modeling and simulation of UUVs’ collaboration in swarm formations, towards obtaining deeper insights related to the critical issues of cybersecurity and interoperability. The research topics, which are constantly emerging in this domain, are closely related to the communication, interoperability, and secure operation of UUVs, as well as to the volume, velocity, variety, and veracity of data transmitted in low bit-rate due to the medium, i.e., the water.

Scour Protections Design Optimization
The offshore wind is the sector of marine renewable energy with the highest commercial development at present. The margin to optimise offshore wind foundations is considerable, thus attracting both the scientific and the industrial community. Due to the complexity of the marine environment, the foundation of an offshore wind turbine represents a considerable portion of the overall investment. An important part of the foundation’s costs relates to the scour protections, which prevent scour effects that can lead the structure to reach the ultimate and service limit states. Presently, the advances in scour protections design and its optimisation for marine envi-ronments face many challenges, and the latest findings are often bounded by stakeholder’s strict confidential policies.

Salinity and Turbidity in the Red Sea
Several industrial and scientific underwater applications require high-speed wireless connectivity. Acoustic communications have low data rates and high latency, whereas attenuation in seawater severely limits radio frequency communications. Optical wireless communication is a promising solution, with high transmission rates (up to Gb/s) and little attenuation in water at visible wavelengths.
