https://orcid.org/0000-0001-7618-0018 Dear Readers,
We are pleased to present this year’s first issue (No. 65) of the Scientific Journals of the Maritime University of Szczecin. This year will bring many new challenges, also for the journal, where we continually focus on improved quality. We would like to thank the authors, reviewers and readers for their contribution to our journal. I hope that we will continue to develop this path together.
This issue presents the research results and authors’ views in seven articles organized into three thematic sections: Civil Engineering and Transport, Mechanical Engineering, and Economics, Management and Quality Science.
The Civil Engineering and Transport section features two articles. The first article presents an analysis of internal forces and roll motion during a nodule loading simulation for a ship at sea. The study carried out a full assessment of a ship’s behaviour during loading, which took into account wave height and period around the Clarion–Clipperton Zone by the use of an operational efficiency index. The second article addresses the International Convention for the Safety of Life at Sea (SOLAS). The Convention aims to improve the safety of life at sea by laying down rules and regulations for the construction of ships and providing models for the documents created.
The Mechanical Engineering section consists of three articles. In the first article, the authors analysed the special configuration of a multi-role moving-column machining centre by the finite element method. In the second article, a CFD-based numerical approach was developed and applied to a trimaran hull in the presence of regular and irregular waves. According to the authors, the proposed CFD method reduces the simulation time and calculation resources needed to determine a ship’s motion. The third article presents the results of the testing of long-distance heat transfer surfaces in marine diesel engines, including elliptical and flat-oval tubes. The study used mathematical models that involved equations from conservation of energy, equations of motion, continuity and state, where the RSM of turbulence was also used to complete the equation system.
The Economics, Management and Quality Science section includes two articles. The first article analyses the factors affecting the performance of VTS operators. Its general conclusion is that the effective work of VTS operators, combined with a specific maritime environment and vessel traffic management support system, are the key determinants for ensuring the reliability and safety of the entire system. The second article’s authors wanted to see if a multi-criteria analysis was appropriate for the evaluation and implementation of energy-efficient mobility in seaports. The multi-criteria model for the selection of the most appropriate energy-efficient mobility solution was tested for two Croatian private marinas.
