The Internet of Things (IoT) is significantly transforming the maritime industry, enabling the generation of vast amounts of data that can drive operational efficiency, safety, and sustainability. This review explores the role and potential of data analysis in maritime IoT applications. Through a series of case studies, it demonstrates the real-world impact of data analysis, from predictive maintenance to efficient port operations, improved navigation safety, and environmental compliance. The review also discusses the benefits and limitations of data analysis and highlights emerging trends and future directions in the field, including the growing application of AI and Machine Learning techniques. Despite the promising opportunities, several challenges, including data quality, complexity, security, cost, and interoperability, need to be addressed to fully harness the potential of data analysis in maritime IoT. As the industry continues to embrace IoT and data analysis, it becomes critical to focus on overcoming these challenges and capitalizing on the opportunities to improve maritime operations.

This study characterises materials that belong to the group of refuse-derived fuels (RDF). This group of materials regarded as an alternative fuel is derived from industrial, municipal solid and commercial wastes. The aim of this study is to evaluate the quality of waste composition, demonstrate statistically different values and the energy efficiency of the fuel derived from waste. Data on incinerated waste were collected from two different sources. The basic physical and chemical parameters of waste include density and water content. The lower heating value (LHV) of waste, chlorine concentration and ash content of two groups of incinerated waste were also evaluated and compared for a given period of time (one year, with monthly breakdown). Statistical analysis indicated the differences in the combustion of waste groups, visualized by box plots and other diagrams to show the distribution of the results. An analysis of exhaust gas parameters was carried out, both in terms of chemical composition and energy parameters. The RDF combustion process was presented through simulations for the adopted conditions of heat recovery. It was found that for each kilogram of RDF, about 3.85 kWh (13,860 kJ) of heat can be obtained. The combustion process was simulated using Aspen Plus software.

The advancement of electric vehicles is linked to the increasing concern about the world’soil resources running out and the problem of global climate change. As global sea trade keepsexpanding quickly, the characteristics of ships also change, as they become bigger, carry morepassengers, and new risky goods emerge, including, for example, electric vehicles. The articlediscusses challenges of preventing fires on ro-ro ships with regard to electric car fires, which arebecoming more recognizable due to their increasing prevalence and consists of two parts. Part 1covers some key challenges of fire safety on the cargo decks of ro-ro ships when an electric carcatches fire and the main aspects of fire safety regulations for seagoing roll-on/roll-off ships inthe ro-ro space. Problematic areas were considered in the following aspects: features of maritimetransport, specifics of cargo carriage on a ro-ro vessel, the difficulty of evacuating sailors andpassengers from a burning ship, specifics of firefighting on a ship, challenges and dangers ofelectric vehicle fires and lack of adequate fire protection and procedures on a ro-ro ship in termsof an electric car fire. The second part of this article presents some possible solutions to improvethe fire safety of ro-ro ships, on cargo decks, and the author’s idea of implementing a new fireprotection device consisting of fire ventilation. No other study has addressed fire safety challengesof ro-ro ships with such depth, especially given the emerging risk of electric cars.
