Abstract:
The management of fleets, especially as part of the state-private interaction, is a complex endeavor influenced by economic, political, and strategic factors. This article delves into the concept of the “convenience flag” as a mechanism for optimizing fleet management, exploring its implications within the evolving landscape of mari-time industries. It analyzes optimization mechanisms for fleet management through the utilization of “conven-ience flags” and offshore zones. The current optimization mechanisms are scrutinized against the backdrop of modern transformations in strategic economic sectors, particularly shipbuilding and maritime transport fleet development. Approaches to financing and balancing state-private interests amid heightened international re-lations are examined in greater detail. Through identifying causal relationships between elements of optimiza-tion mechanisms, particularly in financial operations, asset transactions, and the increased risk of fleet vessel loss, the necessity of upholding state interests in these processes is substantiated. Principles of organizational measures to prevent vessel loss and, consequently, the entities operating under “convenience flags” and off-shore zone jurisdictions, are proposed. In conclusion, the management of fleets through “convenience flags” represents a complex interplay of economic, political, and regulatory considerations. While offering potential benefits in terms of cost efficiency and operational flexibility, it also poses inherent risks to state sovereignty and maritime security. Moving forward, a balanced approach that prioritizes transparency, accountability, and stakeholder engagement is essential to ensure the sustainable and responsible management of fleets in the Russian Federation and beyond.

Abstract:
The article explores the potential applications of artificial intelligence (AI) in maritime fleet management, focusing on improving operational efficiency and reducing costs. An analysis of key technological solutions is presented, including predictive maintenance, intelligent routing systems, crew performance monitoring tools, and energy consumption optimization. It is demonstrated that machine learning algorithms processing vast datasets, such as Automatic Identification System (AIS) data, weather information, and vessel sensor readings, can predict emergency situations and schedule maintenance based on actual equipment wear. The study examines case studies from Maersk, Shell, Wärtsilä, and other companies, highlighting fuel savings of up to 15%, reductions in unplanned maintenance events, and improvements in environmental sustainability. Special attention is given to decision-support systems that integrate diverse data sources into a unified information platform, enabling comprehensive analysis and timely decision-making. The implementation of AI technologies can enhance not only safety levels but also the profitability of maritime transport by optimizing cargo flows and reducing fuel and maintenance costs. The article concludes with practical recommendations for shipping operators transitioning to a "digital" fleet and outlines promising directions for further research. The information presented will be of interest to professionals and researchers in maritime logistics, digital transformation, and operational management who aim to integrate advanced AI-driven models with systems analysis to develop innovative strategies for improving efficiency and reducing costs in maritime fleet management amid global industry dynamics.

Abstract:
Abstract Since the implementation of Emission Control Areas (ECA) in 2015, investment decisions related to abatement technologies represent a crucial task in the maritime industry. Currently, the focus in the maritime sector is on Sulphur reductions due to SECA regulations and the legislative of Global Sulphur Cap that started in 2020. A special challenge appears in maritime fleet management where sets of ships have to be considered, representing portfolios of assets that have to be equipped with a variety of different options of abatement technologies. Modern portfolio theory has been applied to various economic decisions to achieve an optimal allocation of resources among different investment opportunities. The research investigates and discusses the application of the Markowitz´ optimization in the context of SECA regulations for maritime fleets. The optimal investment portfolios are taking into account the three most important compliance options based on the use of low Sulphur fuel, the use of LNG fuel and the use of HFO with a scrubber. The theoretical results are empirically validated by a case of a shipping line operating 10 vessels.

Abstract:
The article is devoted to the project of creating a Digest of Maritime Laws, developed in 1833 in the maritime department and the influence of the experience of Michael Speransky on its key characteristics. Based on archival materials from the Russian State Archive of the Navy and the Manuscripts Department of the Russian National Library, a project for systematization of maritime legislation was investigated, which appeared as an attempt to streamline disparate maritime laws and create a Digest of laws similar to that developed with mid-1820s at the War Ministry. Based on the analysis of the documents of the plan of naval code of 1833, it is shown how the concept of systematization of laws proposed by Michael Speransky was adapted to the realities and characteristics of the navy. In the article the project to create a Digest of Maritime Laws is considered in the context of maritime management reforms initiated by Nicholas I himself and carried out under the leadership of Prince Alexandre Menshikov. These reforms were aimed at overcoming the management crisis in the fleet and corruption. From this point of view, the attempt to streamline laws can be interpreted as an integral part of these transformations, generally aimed at strengthening the presence of supreme power in the fleet. However, unlike the military code, the draft Digest of Maritime Laws of 1833 remained unrealized. The article describes the reasons for the failure of the first real attempt to systematize maritime laws and its place in the history of maritime codification in the 19th century.

Abstract:
The safety and health of merchant seafarers is of grave concern. With the ongoing global pandemic, the weaknesses in the governance structure to protect the safety and health of seafarers have been further exposed. Safety and health on ships is governed by two international instruments, the International Safety Management Code (ISM) and the Maritime Labour Convention 2006 (MLC). Yet, the maritime industry is challenged with how to effectively manage safe and healthy working conditions in the global merchant fleet. Regulations in and of themselves have been found to be inadequate. Other considerations are important such as representative participation, which has been neglected as a viable mechanism in the maritime safety and health regulatory regime. This chapter foregrounds representative participation as necessary for effective safety and health management on ships. It argues that along with enabling regulations and other supports for its effective implementation and practice, representative participation might help to address the challenges in safety and health management on ships.

Abstract:
The world merchant fleet has increased in the last decade producing an increase of fuel consumption and greenhouse gas emissions (GHGs). Thus, the concerns of ship-owners to implement alternatives to improve the fleet efficiency are growing. However, shipowners are facing barriers to implement energy efficiency technologies mainly due to reliability, financial and economic constraints as well as complexity of change. Actually several shipowners are using onboard data measurements systems that collect navigation and propulsion information of their ships. Therefore, after being sent via satellite and stored in data warehouse, these data are being made available to assess the performance of their fleets. This paper describes the use of these data to generate models in order to answer to the following questions: What is the ship with least efficiency in my fleet? What is the best strategy to improve the overall efficiency of my fleet? What is the ship that I should sell in priority? What is the influence of this maintenance policy on the performance of my fleet? The application case of this paper is based on one fleet of 13 ships containing 223 trips that gather approximately 6,844 traveling days. After the definition of the key performance indicators (KPIs), a data envelopment analysis (DEA) models is discussed. Then, a multicriterion decision analysis (MCDA) model is compared to the DEA outputs. The results suggest that this new methodology can efficiently provide a multicriteria decision framework to shipowners avoiding engineers’ subjectivity. These findings offer a new way to address efficiency and performance in ship management.

Abstract:
The Autoregressive Integrated Moving Average (ARIMA) model has proven to be a powerful statistical prediction technique due to its simplicity and wide acceptance. Its main application lies within the realms of economics and social sciences, although not limited to these. This study explores its utilization in the context of maritime safety within the Galician fishing fleet. Specifically, its application is proposed for predicting the vessels involved in accidents quarterly index. The Galician fishing environment, of significant socioeconomic relevance to the region, is affected by serious accidents compromising its sustainability. The vessels involved in accidents index, derived from investigation reports by the Maritime Accident Investigation Commission (CIAIM) and fleet data collected by the European Fishing Vessel Register, depicts the annual evolution of these accidents in relation to the decreasing fishing capacity of the fleet. Analysis of quarterly values for the period between 2011 and 2021 indicates that accidents are recurrent and persistent in nature. Using the proposed ARIMA model, index values for the quarters of 2022 were forecasted and the model's effectiveness was validated by comparing the obtained results with actual observed data. The outcomes support the utility of ARIMA model as a tool for predicting maritime accidents and pave the way for future research in the field of safety. In the studied case, this predictive capacity supports proactive safety management on board while providing a solid foundation for the adoption of preventive initiatives in both public and private sectors within the industry.

Abstract:
The Arctic is a vast area with many future economic possibilities for the oil and gas, shipping and the fishing industries. The climate is harsh, the environment vulnerable, but the potential profits from future expansion in the area are huge. The on-going public debate on the Arctic includes discussions both for and against industrial development in these areas, however the reality is that as resources become scarcer in other parts of the world, Arctic expansion will become inevitable. Therefore adequate preplanning of the activities, understanding of the operational environment and development of barriers against undesired events becomes infinitely more important for sustainable, reliable and safe operation in the future. The fishing fleet has been operating in the Arctic region for decades and while the safety for the fishers is questionable, it is a matter of resources that drove and will continue to drive this expansion. The IMO’s Polar Code for shipping is now under construction and the fishing fleet will have to comply with this and other regulations for future operations in the Arctic. This paper focuses on the maintenance and safety management regimes and requirements of the fishing fleet currently operating in the Arctic. With long distances to service and help, and a short operating season, a reliable system is a mandatory requirement for the economic stability of these operations. Mutual benefits may be gained if operational experiences from fishing can be utilized by the oil and gas industry and ship transport when moving their operations into the arctic areas, whereas the fishing fleet can improve their safety performance through closer alignment with those standardized procedures applied in other industries.

Abstract:
In this paper, we will investigate social factors that indirectly affect ship energy efficiency, intended or not. These include fleet management, charter party agreements, piracy, regulatory factors such as Emission Control Areas, port congestion and port awareness, economic factors such as cost of fuel and charter rates, and human factors (safety, comfort, attitude, and education). I call them “social factors” because they all have the characteristic of being created by our society, rather than being driven by the laws of physics. In comparison, physical factors include such things as hull and propeller design and condition, draft and trim, speed through water, engine state of tune, weather effects such as waves, wind and storms, ocean currents, and fuel quality. While optimizing for physical factors can lead to energy and cost reductions of 5-20%, focusing our attention on social factors can lead to even higher net savings, providing greater return on investment. First, we will review how social factors differ from physical ones. Then we will explore several social factors that affect operating efficiency that are frequently overlooked as having potential for optimization, or at least taken for granted as being unavoidable. Finally, we will examine specific social factors where existing technology, either as is or in modified form, may be applied toward realizing substantial return on investment in terms of operating costs, along with reductions of fuel consumption and associated greenhouse gas emissions.

Abstract:
Complex Event Recognition (CER) systems detect event occurrences in streaming time-stamped input using predefined event patterns. Logic-based approaches are of special interest in CER, since, via Statistical Relational AI, they combine uncertainty-resilient reasoning with time and change, with machine learning, thus alleviating the cost of manual event pattern authoring. We present WOLED, a system based on Answer Set Programming (ASP), capable of probabilistic reasoning with complex event patterns in the form of weighted rules in the Event Calculus, whose structure and weights are learnt online. We compare our ASP-based implementation with a Markov Logic-based one and with a crisp version of the algorithm that learns unweighted rules, on CER datasets for activity recognition, maritime surveillance and fleet management. Our results demonstrate the superiority of our novel implementation, both in terms of efficiency and predictive performance.

Abstract:
Liquified natural gas (LNG) as a fuel source for shipping is a ready-made solution for the maritime industry. LNG is a clean fuel that meets the current environmental regulations set by the International Maritime Organization (IMO) to lower the sulfur content of marine fuel from 3.5% to 0.5% by January 2020. LNG is also competitive in terms of price and the increasing availability of fueling terminals. This technological readiness promotes the adoption of LNG powered ships, and the demand for such ships is increasing and is projected to increase in the future. LNG fuelled ships (LFS) comply with the tightened emission regulations, and major industry players have predicted that more than 10% of the world fleet will be using gas as a fuel by 2035. The rapid increase in the design and use of LFS has to be carefully monitored to ensure a successful transition. The design of ship and containment systems for LFS is usually carried out using risk-based design processes. Monitoring and advisory solutions are critical to ensure that changes take place in a safe manner. The experience and lessons learned from designing a suitable database framework and data analytics for traditional ship design are presented, and the knowledge transfer and applications for LFS are discussed. Additional critical parameters that are specific to LFS are discussed, and procedures required to ensure quality data collection to provide necessary solutions for the future fleet are presented. The importance of monitoring quality and quantity of the bunkering process with traditional fuel is outlined along with strategies to adopt and promote infrastructure readiness for the increase in LFS use. Data management and big data analysis for decision making is becoming increasingly apparent in many industries, including the shipping industry. Therefore, the inclusion of the systematic design of data acquisition and analytics systems for newly designed LFS is needed. This will accelerate data-driven knowledge generation and design improvements, promote safe and efficient ship operations, and provide a solid foundation for automation. The synergistic blending of solutions from fuel suppliers, engine makers, containment providers, sensor makers, logistics and government will be needed to ensure the global growth and sustainability of LNG fuelled shipping.
