Opis:
In recent years, there has been an intensification of work on the autonomy of means of transport, which also applies to ships. Modern ships are already equipped with crew decision support systems and numerous diagnostic systems. Increasingly more systems are installed on ships that can operate without human integration. This situation leads to the development and use of fully autonomous ships. This overview publication briefly describes the main features of the construction and operation of autonomous ships, including some examples of structures already demonstrated in recent years. In summary, the author presents comments that provide a contribution to the discussion on the autonomy of means of maritime transport.

Opis:
This paper explores the use of machine learning and deep learning artificial intelligence (AI) techniques as a means to integrate multiple sensor modalities into a cohesive approach to navigation for autonomous ships. Considered is the case of a fully autonomous ship capable of making decisions and determining actions by itself without active supervision on the part of onboard crew or remote human operators. These techniques, when combined with advanced sensor capabilities, have been touted as a means to overcome existing technical and human limitations as unmanned and autonomous ships become operational presently and in upcoming years. Promises of the extraordinary capabilities of these technologies that may even exceed those of crewmembers for decision making under comparable conditions must be tempered with realistic expectations as to their ultimate technical potential, their use in the maritime domain, vulnerabilities that may preclude their safe operation; and methods for development, integration and test. The results of research performed by the author in specific applications of machine learning and AI to shipping are presented citing key factors that must be achieved for certification of these technologies as being suitable for their intended purpose. Recommendations are made for strategies to surmount present limitations in the development, evaluation and deployment of intelligent maritime systems that may accommodate future technological advances. Lessons learned that may be applied to improve safety of navigation for conventional shipping are also provided.

Opis:
The progressing automation of maritime transport, including the introduction of autonomous and/or unmanned ships, calls for the development of communication principles, particularly conversations currently carried out verbally. The work in this field is intended to improve the safety of maritime transport. This article describes research on automatic communication in the form that will support navigators responsible for ship conduct. The processes of inference and conversation management are described. The developed methods are based on standard marine communication phrases. The presented example conversation between navigators is supported by an automatic communication system. The work herein described aims at the creation of procedures for communication at sea between autonomous ships.

Opis:
The article presents regression formulas for calculating the friction resistance RF and the total resistance RT of ship models in the 2.0–10.0 m range. The method for calculating the total resistance is novel and applies to the design models of an unmanned surface vessel (USV) for experimental testing of autonomous control. For both regression models (RF and RT), statistical and substantive tests were performed (the results of the calculations were compared with the experimental measurements). In both cases, convincing results were obtained, which have confirmed the possibility of their use at the preliminary design stage of unmanned ship models.

Opis:
The first ever attempt at fully autonomous dock-to-dock operation has been tested and demonstrated successfully at the end of 2018. The revolutionary shift is feared to have a negative impact on the safety of navigation and the getting of real-time situation awareness. Especially, the centralized context onboard could be changed to a distributed context. In navigation safety domain, monitoring, control, assessment of dangerous situations, support of operators of decision-making support system should be implemented in real time. In the context of autonomous ships, decision-making processes will play an important role under such ocean autonomy, therefore the same technologies should consist of adequate system intelligence. At the same time, situation awareness is the key element of the decision-making processes. Although there is substantial research on situation awareness measurement techniques, they are not suitable to directly execute quantitative processing for the situation awareness of autonomous ships navigation. Hence, a novel quantitative model of situation awareness is firstly proposed based on the system safety control structure of remotely controlled vessel. The data source is greatly limited, but the main result still indicates that the probability of operator lose adequate situation awareness of the autonomous ship is significantly higher than the conventional ship. Finally, the paper provides a probabilistic theory and model for high-level abstractions of situation awareness to guide future evaluation of the navigation safety of autonomous ships.

Opis:
A paradigm shift is presently underway in the shipping industry promising safer, greener and more efficient ship traffic. In this article, we will look at some of the accidents from conventional shipping and see if they could have been avoided with autonomous ship technology. A hypothesis of increased safety is often brought forward, and we know from various studies that the number of maritime accidents that involves what is called “human error” ranges from some 60‐90 percent. If we replace the human with automation, can we then reduce the number of accidents? On the other hand, is there a possibility for new types of accidents to appear? What about the accidents that are today averted by the crew? This paper will present a method to assess these different aspects of the risk scenarios in light of the specific capabilities and constraints of autonomous ships.

Opis:
This paper represents the first stage of research into a multi-objective method of planning safe trajectories for marine autonomous surface ships (MASSs) involved in encounter situations. Our method applies an evolutionary multiobjective optimisation (EMO) approach to pursue three objectives: minimisation of the risk of collision, minimisation of fuel consumption due to collision avoidance manoeuvres, and minimisation of the extra time spent on collision avoidance manoeuvres. Until now, a fully multi-objective optimisation has not been applied to the real-time problem of planning safe trajectories; instead, this optimisation problem has usually been reduced to a single aggregated cost function covering all objectives. The aim is to develop a method of planning safe trajectories for MASSs that is able to simultaneously pursue the three abovementioned objectives, make decisions in real time and without interaction with a human operator, handle basic types of encounters (in open or restricted waters, and in good or restricted visibility) and guarantee compliance with the International Regulations for Preventing Collisions at Sea. It should also be mentioned that optimisation of the system based on each criterion may occur at the cost of the others, so a reasonable balance is applied here by means of a configurable trade-off. This is done throughout the EMO process by means of modified Pareto dominance rules and by using a multi-criteria decision-making phase to filter the output Pareto set and choose the final solution.

Opis:
Modern industries often attempt to implement innovations that have a disruptive potential. In shipping, this included a largely unsuccessful introduction of nuclear propulsion in late 20th century, among other concepts. Nowadays, introduction of increased autonomy is being associated with prospects of various industry-wide benefits, but is also burdened with serious obstacles. The objective of this study is to investigate reasons behind the failure of nuclear-powered merchant ships introduction and whether lessons learnt from it can be applied to the prospective implementation of autonomous merchant ships. It advocates that three aspects of maritime technology are crucial for its successful implementation: perceived level of safety, economical feasibility, and legal setup.

carriage of goods by sea
Opis:
When performing the carriage of goods by sea, each contracting party, shipowner and charterer, has a number of rights and obligations. In legal sources which regulate carriage of goods by sea, in particular contracts concluded between parties, international conventions and national laws, standard clause is shipowner's obligation to provide a seaworthy vessel. Such obligation implies that the vessel must be able to carry and keep the contracted cargo in good condition and also have required number of qualified crew. On the other side, charterer's obligation is to order the vessel to sail to ports/berths which are considered safe (safe port warranty). Also, legal sources of carriage of goods by sea regulate liability issues for loading and discharging operations, the limitation of the shipowner’s liability and application of provisions related to exclusion of liability. All of the above represent important rights and obligations of the regulation of the carriage of goods by sea, and so regulated thus far have been common in the carriage of goods by sea by traditional vessels. However, the question that arises is how the problems related to the carriage of goods by sea will be regulated when such carriage is performed by autonomous vessels. In other words, there is a question about interpretation of the provisions of seaworthiness, safe port warranty, liability and the limitation of the shipowner’s liability and exclusion of liability in the carriage of goods by sea by autonomous ships. The purpose of this paper is comparison of problems related to the carriage of goods by sea between the traditional and autonomous vessels, and regarding the regulation of seaworthiness, safe port warranty, liability, the limitation of the shipowner’s liability and exclusion of liability. The results of this comparison lead to the conclusion that reconsideration of the content of the listed terms is needed when we are talking about carriage of goods by sea by autonomous vessels.

Opis:
Vessel Traffic Services (VTS) are to improve the safety and efficiency of vessel traffic and to protect the marine environment by interacting with the ship’s traffic in monitored coastal areas. Today, VTS operators are maritime professionals with nautical education from a university or technical college and practical experience on board. This experience and nautical background is a key element of the work as a VTS operator. It is to support understanding the daily work. The current situation in the maritime domain is undergoing substantial changes, such as introducing new technologies, implementing the e-Navigation concept based on sustainable digitalization and ambitions to realize unmanned and autonomous shipping. This paper will present preliminary results of a pilot study conducted in VTS Centres along the coast of North and Baltic Sea and discuss selected options and opportunities for education and training of future VTS operators, which might not have the advantage of practical sea experience anymore.

Opis:
Over the last few decades, the International Maritime Organization (IMO) has very heavily utilized the Safety of Life at Sea (SOLAS), 1974 Convention as the main legal instrument (and implementation tool) concerning safety at sea for merchant vessels engaged in international trade. During this more than a century of existence and continuous improvement of the Convention, wide-ranging safety risks have been addressed via SOLAS and certain relevant “supporting” Codes, covering for example the issues of design, construction and equipment of ships, as well as paving the way for the introduction of a structured framework of operational procedures that ensures a high level of professional performance for the crew onboard those seagoing vessels (the International Management Code for the Safe Operation of Ships and for Pollution Prevention-ISM Code) and even including human factors topics. Until this point in time, the IMO has developed the SOLAS Convention with fourteen (14) chapters that are covering all the main risks associated with shipping operations and are working in parallel with other related Conventions and Codes to enhance the level of safety at sea, under a holistic approach that is working under the principle of interrelation. This paper aims to briefly discuss SOLAS’ history of development and highlight just a few of those important risks that this Convention is addressing, with certain emphasis on the topic of “safety of navigation”. Apart from helping to understand the way this Convention and other IMO’s legal instruments are interrelated, it will also provide a few educated guesses about the “upcoming” challenges that in the near future should also be included into the scope of the SOLAS, with the topic of Maritime Autonomous Surface Ships (MAAS) clearly standing out.

Opis:
The collision regulations include several qualitative terms without providing guidance as to how these terms could be understood in quantitative terms. These terms must therefore be interpreted by navigators, which poses a problem for autonomous ships. Extend the knowledge of how navigators interpret the collision regulations, with a specific focus on how they interpret the rule covering the requirement to proceed at a safe speed. Qualitative study based on interviews of a convenience sample of eight Norwegian navigators. Data was analysed with systematic text condensation. Navigators characterise safe speed as a speed in which they have control. Navigators do not look at different factors mentioned in the collision regulations in isolation, but within the context of the situation. Determining the safe speed of a vessel is more complicated than made out in the literature. As autonomous ships will have to cooperate with conventional vessels, their programming must include the knowledge of how the collision regulations are interpreted by human navigators.
