  • Marine Coolant Fluids’ Effect on the Mechanical Properties of Glass Fiber-Reinforced Composites
    Dean Bernečić, Marino Mikelić, Goran Vizentin
    Pomorstvo, 2026
    This study examines the effect of coolant and antifreeze solutions such as distilled water, ethylene glycol-based antifreeze with organic acid technology (OAT), and ethylene glycol-based antifreeze with inorganic inhibitors and glycerol (IAT/HOAT) on the tensile strength of glass fiber-reinforced polyester (GFRP-P) and vinyl ester (GFRP-VE) composites. Standardized specimens were produced and immersed in these solutions for three months at room temperature. Following exposure, tensile tests were conducted using the universal testing machine, supported by microscopic analysis to evaluate surface damage and internal structural changes such as composite layer delamination. The tensile test results show the highest decrease in tensile strength for GFRP-P specimens immersed in HOAT antifreeze (16.3%), whereas GFRP-VE specimens exhibit only a minimal reduction (3.4%). This difference is attributed to the higher chemical aggressiveness and alkalinity of the HOAT antifreeze. Furthermore, the decrease in the tensile strength of GFR-P exposed to OAT antifreeze is 6.1%, whereas GFRP-VE demonstrates a significantly smaller reduction of 1%, which can be attributed to the less aggressive chemical composition of the OAT formulation compared to HOAT. In contrast, the influence of distilled water on GFRP-P specimens is manifested as a tensile strength decrease of 12.7%, whereas GFRP-VE specimens show a reduction of 11%, attributed to the fluid’s density and the rate of hydrolytic degradation. These results contribute to a deeper understanding of the effects of various coolant media on the performance of GFRP in marine cooling systems, highlighting GFRP-VE as a more suitable matrix for prolonged exposure to coolant environments.
  • Towards Decarbonization of the Maritime Transport Sector: A Review of Hydrogen as an Alternative Marine Fuel
    Fran Torbarina, Josip Dujmović, Goran Vizentin, Mateo Kirinčić
    Pomorstvo, 2026
    This review examines the current landscape of hydrogen production technologies, including thermochemical, electrochemical, and biological methods, highlighting their efficiencies, feedstock requirements, and environmental implications. Furthermore, the paper explores the challenges and advancements in hydrogen storage technologies, primarily on compressed gas, liquefied hydrogen, and solid-state storage. Hydrogen technology across industries, from transportation, to grid energy storage and industrial processes are discussed, with a focus on maritime sector applications, showcasing hydrogen’s versatility and decarbonization potential. Despite its promise, large-scale hydrogen adoption is constrained by high costs, infrastructure limitations, and energy efficiency concerns. This review aims to provide a foundational understanding for researchers and policymakers to support the advancement of hydrogen as a key component in future energy systems.

  • Application of VR Technology for Maritime Firefighting and Evacuation Training—A Review
    Goran Vukelic, Dario Ogrizovic, Dean Bernecic, Darko Glujic, Goran Vizentin
    Journal of Marine Science and Engineering, 2023
    Firefighting and evacuation training are important tasks in maritime education and training, especially for crews working on large passenger ships, to ensure the safety of the vessel, cargo and passengers. With the evolution of virtual reality (VR) technology and the introduction of wearable hardware, a change in paradigm has happened in firefighting and evacuation training where these new technologies are being introduced. This paper serves as a review on the use of VR technology in maritime firefighting and evacuation training, trying to answer the following questions: what is the current state of using VR technology, and what are the research gaps that need to be addressed to further accelerate the implementation of VR? Research shows that other industries have adopted the use of VR technology relatively quickly, but the maritime industry still seems reluctant. As for the research gaps, the physics-based modelling of fire spread is discussed along with two other topics: the lack of immersive solutions for evacuation and the potential for developing search and rescue scenarios onboard a ship.

  • Prediction of the Deterioration of FRP Composite Properties Induced by Marine Environments
    Goran Vizentin, Goran Vukelic
    Journal of Marine Science and Engineering, 2022
    In this paper, a model for the prediction of fatigue life degradation of fiber-reinforced (FRP) composite materials exposed for prolonged periods to real marine environments is proposed. The data collected during the previous phases of a more comprehensive research of real marine environment-induced changes of mechanical properties in FRP composites are used to assess the influence of these changes on the durability characteristics of composites. Attention is paid to the classification societies’ design and exploitation rules on this matter. The need for the modification of the process used for obtaining composite material S–N curves, considering the influence of the marine environment, is studied. A regression analysis of the experimental data is conducted, resulting in a mathematical model of strength degradation over time. The regression analysis shows an acceptable correlation value. The S–N curves for E-glass/polyester composites with three different fiber layout configurations are evaluated and modified to encompass the findings of this research.
