: The process of decarbonization and the pursuit of zero ‐ emissions growth are a challenge for maritime transport, while strict environmental regulations regarding greenhouse gas emissions call for changes in both organizational and technological processes. The aim of the article is to present the problem of carbon footprint in relation to the maritime transport industry . The article discusses the negative impact of sea transport on the environment. The main research objective was to shed light on carbon footprint in the context of maritime transport as well as to identify the possibilities of its reduction, including through regulatory measures. Various research methods were used in the study, including a literature review, a review of the documentation of IMO regulations, reports and an analysis of technologies implemented to reduce pollutant emissions in maritime transport.

: Successful and sustainable development of county ports implies identification and assessment of all the elements that affect their performance. Several factors determine port’s performance out of which the most significant one is its position, usually in the centre of a town/settlement. This situation is the most common in the Mediterranean countries where small ports are usually in the centre of a settlement. Such a location of ports affects their urban and spatial planning, i.e., it affects planning the development of county ports.

: This paper aims to cover a gap in maritime literature by analysing the performance of the international fleet through the BIMCO Shipping KPI System databases, and by highlighting the necessity for the adoption of Global Performance Indicators to serve the needs of a sustainable maritime industry. The paper investigates the complex interrelations of the various types of performance in shipping, consisting of 57,622 ships of all commercial types, operated from 26 countries, covering the environmental, health, safety management, HR management, navigational safety, operational, security, and technical performance. Results indicate that countries rank differently with regards to the aggregated performance of their respective shipping companies, signifying different managerial approaches. This paper contributes to the discourse of maritime governance, aiming to be of interest to all maritime stakeholders dealing with marine policies and institutional arrangements for the management and regulation of international shipping.

: This article explores the use of Light Detection And Ranging (LiDAR) derived point clouds to extract the shoreline of the Lake K ł odno (Poland), based on their geometry properties. The data collection was performed using the Velodyne VLP ‐ 16 laser scanner, which was mounted on the HydroDron Unmanned Surface Vehicle (USV). A modified version of the shoreline extraction method proposed by Xu et al. was employed, comprising of the following steps: (1) classifying the point cloud using the Euclidean cluster extraction with a tolerance parameter of 1 m and min. cluster size of 10,000 points, (2) further filtration of boundary points by removing those with height above 1 m from the measured elevation of water surface, (3) manual determination of a curve consisting of 5 points located along the entire shoreline extraction region at a relatively constant distant from the coast, (4) removal of points that are further from the curve than the average distance, repeated twice. The method was tested on the scanned section of the lake shoreline for which Ground Control Points (GCP) were measured using a Global Navigation Satellite System (GNSS) Real Time Kinematic (RTK) receiver. Then, the results were compared to the ground truth data, obtaining an average position error of 2.12 m with a standard deviation of 1.11 m. The max error was 5.54 m, while the min. error was 0.41 m, all calculated on 281 extracted shoreline points. Despite the limitations of this parametric, semi ‐ supervised approach, those preliminary results demonstrate the potential for accurate shoreline extraction based on LiDAR data obtained using an USV. Further testing and optimisation of this method for larger scale and better generalisation for different waterbodies are necessary to fully assess its effectiveness and feasibility. In this context, it is essential to develop computationally efficient methods for approximating shorelines that can accurately determine their course based on a set of points.

: Maritime education and training (MET) are under constant pressure from the maritime industry, characterized by extremely rapid development. Due to the high risk in the transport and handling of crude oil, seafarers employed on oil tankers are required to have skills and competencies well above the minimum education standards set by the International Maritime Organization (IMO) and the International Convention on Standards of Training, Certification and Watchkeeping (STCW). Therefore, tanker companies should provide additional training for their employees to ensure the fundamental goals of zero ‐ accident rates and reduce human error to a minimum. This especially applies to seafarers at the management level, who must have the competence and knowledge to operate oil tankers at the highest professional level. This paper examines the current challenges in education and the required competencies of seafarers at management levels concerning the rapid growth and development of the tanker industry. In addition, some shortcomings regarding the current form of education and training have been considered, and recommendations for the future upgrade of the education and training system for seafarers at the management level are provided.

: Design and construction of container ships follow consolidated requirements, with standard consideration of fire management. Indeed, cargo fires can have important consequence on crewmembers and cargoes, as well as impacting coastal zone and marine environment. Innovative strategies include prevention of events and mitigation of consequences. Digital solutions, providing with situational pictures onboard and around the vessel are fundamental for new fire management solutions, seamless and integrated into the vessel IT infrastructure, according to IMO regulations and the recent EMSA CARGOSAFE Report. The assessment of these solutions requires theoretical evaluation, validation activities in simulated environment and demonstration activities in real environments, with use cases to prove feasibility and benefits. This paper, after a review of traditional preventing and mitigating solutions against fire and an analysis of container ships fires, proposes applicable innovative technologies and operational measures, emerging problems for their potential implementation and requirements for virtual and real tests design.
