Special Issue Information

Dear Colleagues,

We would like to invite submissions to this Special Issue on the subject of “Innovations and Inventions in Ocean Energy Engineering”.

As the demand for energy becomes higher, climate change, mostly induced by anthropogenic emissions, represents a reality that has to be considered, and effective actions should be taken very quickly. The energy sector is responsible for about three quarters of these emissions. From this perspective, the drastic reduction in CO2 emissions represents an issue of highly increasing importance.

As we all know, offshore energy, and especially Offshore Renewable Energy (ORE), is abundant, and there are large spaces in both offshore and nearshore areas that can be considered for extracting various kinds of energy. Furthermore, the technologies currently associated with ocean energy extraction are very significant for achieving the expected targets in energy efficiency and environmental protection. Research into offshore wind has experienced outstanding success in the last decade and advances are also expected for other ocean technologies. At the same time, there are still important challenges related to the implementation of cost-effective technologies that could survive in the harsh marine environment.

From this perspective, the target of this Special Issue is to contribute to the sustainable energy agenda through enhanced scientific and multi-disciplinary works, aiming to improve knowledge and performance in harvesting ocean energy. We strongly encourage the submission of papers that provide innovative technical developments, reviews, case studies, and analytics, as well as assessments and manuscripts targeting different disciplines which are relevant to ocean energy extraction and to the associated advances and challenges. Expected climate change effects in marine environments are also topics of high interest for this Special Issue.

This study examines the impact of monitoring, reporting, and verification (MRV) system indicators on the costs associated with the emissions trading system (ETS) of the maritime sector in the European Union. Since maritime transport has recently been incorporated into the ETS, it becomes essential to understand how different operational and environmental factors affect the economic burden of shipping companies and port competitiveness. To this end, a model based on Bayesian networks is used to analyse the interdependencies between key variables, facilitating the identification of the most influential factors in the determination of the costs of the ETS. The results show that fuel efficiency and CO2 emissions in port are decisive in the configuration of costs. In particular, it was identified that emissions during the stay in port have a greater weight than expected, which suggests that strategies such as the use of electrical connections in port (cold ironing) may be key to mitigating costs. Likewise, navigation patterns and traffic regionalisation show a strong correlation with ETS exposure, which could lead to adjustments in maritime routes. This probabilistic model offers a valuable tool for strategic decision-making in the maritime sector, benefiting shipping companies, port operators, and policymakers. However, future research could integrate new technologies and regulatory scenarios to improve the accuracy of the analysis and anticipate changes in the ETS cost structure. Full article
