Content available A theoretical analysis of contemporary vessel navigational systems: assessing the future role of the human element for unmanned vessels

This article aims to investigate the contemporary challenges of electronic navigation and assess the appropriate amendments should autonomous vessel technology becomes widespread in the near future. Vessel control systems and maritime communication are essential and sending and receiving alarm signals is critical to contemporary ship navigation. Numerous location and shipping information systems, such as GPS, Loran-C, and Decca, have arisen in recent decades to improve navigational safety. Other systems, including VHF and Inmarsat, have been developed to enhance the efficiency of maritime communication on board and to transmit risk and safety-related data. Additionally, safe navigation requires systems like Navtex, EGS, DSC, Epirb, and others [1].

The German-funded FernSAMS project aimed at the development of an unmanned, remote-controlled tug operation with AR/VR technology. After an extensive simulation test with ship-handling simulators, the developed FernSAMS AR/VR system has now been in-situ tested with a scale model of the tug. The model test results showed very robust stability in remote operations with improved situational awareness with the VR/AR system and sensors. After a short introduction of the FernSAMS concept as well as some first insights into FernSAMS Human-Machine-Interface tests within the simulator, this paper introduces the technical setup of the scale-model tests being conducted with the FernSAMS concept to test the operational and technical feasibility of AR/VR-based remote control. This includes an overview of the systems and sensors integration and an analysis of the effectiveness of AR/VR system combined with 360-degree video streaming.

W artykule omówiony zostało zagadnienie rozwoju bezzałogowych, autonomicznych jednostek pływających. Zaprezentowano argumenty wskazujące na konieczność rozwoju żeglugi w tym kierunku: poprawa bezpieczeństwa nawigacji i środowiska pracy marynarzy oraz obniżenie kosztów eksploatacji połączonych z ochroną środowiska morskiego. Przedstawiono i omówiono również szczegółowo zagadnienia, kierunki, w których muszą podążać badania, aby stworzyć finalnie jednostkę częściowo lub w pełni autonomiczną.

The article discusses the issue of development of unmanned, autonomous vessels. Presented arguments pointing that the needs for navigational development in this direction are: improving navigational safety and working environment of seafarers reduce operating costs associated with the protection of the marine environment. Presented the topics and directions in which to follow the research and discussed in detail in direction to eventually create partially or fully autonomous vessel.

An unmanned merchant vessel seems to be escaping from the stage of idea exploration. Once the concept proofs its safety, it may become a part of maritime reality. Although the safety aspect of such a ship has been addressed by a handful of scholars, the problem remains open. This is mainly due to lack of knowledge regarding actual operational circumstances and design of unmanned ships, which are yet to be developed. In the attempt of bridging this gap, the risk analysis associated with unmanned ships needs to be carried out, where all relevant hazards and consequences are assessed and quantified in systematic manner. In this paper we present the results of a first step of such analysis, namely the hazard analysis associated with the unmanned ships. The list of hazards covers various aspects of unmanned shipping originating from both design and operational phases of vessel’s life. Subsequently the hazards and related consequences are organized in a casual manner, resulting in the development of a structure of a risk model.
