Abstract:

The ongoing issues in global supply chain disruptions have raised many concerns of port productivity, among which port congestion is a key issue. This article implements an integrated tactical–operational optimization framework which raises the capabilities of port information systems to deliver smarter decision-making processes in ports through a decision support system. To this end, we developed a library of multiple smart models for the optimization of port operations, independently engaged in parallel but mathematically coordinated to achieve autonomous real-time distributed optimization, using a novel event-driven structure to enable future implementations using digital twins. The framework was tested to benchmark different commercial solvers on several real instances for the port under study. The results show a strong improvement in port operational planning.

Abstract:

With the continuous development of global trade, the Beilun port area of Ningbo Zhoushan Port, as an important node of international shipping, its efficient and orderly container dredging operation is crucial to ensure the overall operational efficiency of the port and the stability of the regional supply chain. However, the actual operation is faced with multiple constraints such as fluctuating berth utilization rate, complex truck scheduling, tight yard space, and so on, which need to be optimized by scientific means. To achieve more efficient container transport, it is necessary to further optimize and improve sea-rail intermodal transport to improve the efficiency of port container operations. Therefore, this paper is based on the background of the rapid development of sea-rail intermodal transport of port containers, focusing on the problem of dredging operation of container terminals in the Beilun port area of Ningbo Zhoushan Port, through the analysis of the characteristics and influencing factors of container dredging operation, research on the optimization of container dredging scheme and put forward optimization scheme for the problem of dredging in Beilun Port Area of Ningbo Zhoushan Port, which is aimed at improving the efficiency and economy of container dredging operation and the efficiency of container dredging operation in Beilun port area through the advanced modeling and simulation technology. Through advanced modeling and simulation technology, it aims to effectively improve the efficiency and economy of container dredging operations in the Beilun port area, to cope with the increasing throughput pressure and the challenges of a complex logistics environment, and to provide theoretical support and practical guidance for the development of China’s sea-railway intermodal transport.

Abstract:

Maritime transport is a pivotal logistics mode for the long-distance and bulk transportation of goods. However, the intricate planning involved in this mode is often hindered by uncertainties, including weather conditions, cargo diversity, and port dynamics, leading to increased costs. Consequently, accurate estimation of the total (stay) time of the vessel and any delays at the port are essential for efficient planning and scheduling of port operations. This study aims to develop predictive analytics to address the shortcomings in the previous works of port operations for a vessel’s Stay Time and Delay Time, offering a valuable contribution to the field of maritime logistics. The proposed solution is designed to assist decision-making in port environments and predict service delays. This is demonstrated through a case study on Brazil’s ports, where the best performance is observed for tree-based methods. Additionally, feature analysis is used to understand and interpret key factors impacting maritime logistics, enhancing the overall understanding of the complexities involved in port operations.

Abstract:

In Finland, the connections to global maritime transportation logistics systems are an essential part of the national critical infrastructure. As a part of maritime logistics systems, the port's operations are important elements for global maritime traffic and the transportation supply chain. Digitalization of seaport services makes it possible to increase the efficiency of terminal systems in the logistic processes. At the same time, port logistic processes can notably reduce its CO2 emissions by optimizing port operations. The improvement of port processes relies very much on the development of Information and Communication Technology (ICT) and Industrial Control Systems (ICS) or Operation Technologies (OT) systems. In port environment there are parts that are controlled (ICS/OT) from the cyber environment but directly interact with the physical surroundings. These are called Cyber-Physical Systems (CPS). In this environment, the cyber security aspects of the port logistic need to be addressed. In Finland, the Port SMARTER research program has been on the way since 2021. The aim of the program is to create port services within new technology solutions, and that way improve cargo and people flows while improving the experience for all stakeholders. However, this development increase also complicated system dimensions in the use of ports and makes port operations complex systems of systems environment characterized by a conglomeration of interconnected networks and dependencies. This paper describes a practical approach to risk assessment work regarding the SMARTER research case. It provides a comprehensive cyber security investigation approach to port operations at the system level. In risk assessment work, the paper emphasizes the importation of description of probabilities to defend the system element against estimated probabilities of cyber-attacks at all parts of port processes. The findings of the study are related to the comprehensive cyber security architecture of the SMARTER research goals. The following research interests are related to the issue: "How a comprehensive cyber security investigation can be conducted in smart ports operations?” This paper emphasizes cyber security risks assessment work should be covered from services for operation, information flows in and between systems, as well as electricity supplies to achieve holistic risks assessment in the smart terminal process.

Abstract:

In recent decades, international shipping trade has grown considerably and ports have been extended in order to satisfy the demands of new ships and cargo. Port management has become a difficult task due to the high number of simultaneous operations in ports and the random nature of the agents that are involved in port operations (climate agents, ship arrivals). This makes necessary an aid-decision making tool that reproduces maritime operations and estimates the uncertainty of the port performance. In this work, the software, based on the methodologies proposed in Benedicto et al (2013) and GarcÃa Morales et al (2015), is presented. The software has a user-friendly interface, reproduces port operations for a given case and provides a set of indicators that measure the performance of the simulated case, like waiting times or occupancy of berths and harbor services. Port performance is characterized from a statistical point of view. Software validation, with Algeciras Port (Spain) as pilot port, is also presented.

Abstract:

In line with the quality management principles applied within a functional settlement of an organization, unconcerned of the size or principal object of activity, port operators should be treated as operational entities carrying out specific activities, aiming to achieve specific objectives, that are prior determined but in dependence with their location and role determined alongside the port logistic chain. The process-based approach involves establishing the processes and sub-processes applied to achieve the port operator's entire set of objectives, functions and tasks. As with any business, the company aims at lowering costs, delivering better, consistent and predictable results, focusing on priority. These can be more easily achieved through a process approach that allows the systematic definition of the activities necessary to achieve the desired outcome, setting clear and quantifiable responsibilities for key management activities, analysing and measuring the capability of core activities, identifying links between key activities and the organization's functions, focusing on the elements that can improve the organization's activities (resources, methods and materials) and assessing the risks, consequences and impact of activities on all stakeholders. Carrying out the process map, identifying the data stream, establishing input and output data are the first steps applied in orderto achieve a process model that will further allow the identification of indicators to improve the quality of the services provided and consequently to ensure the satisfaction of customers and other stakeholders.

Abstract:

The loading and unloading process of ships, known as stevedoring, is a critical operation in ports that significantly affects the efficiency of cargo handling and port operations. This study aims to analyze the stevedoring methods used in Tanjung Perak Port, Surabaya, to enhance productivity. A qualitative approach was employed, including observation, interviews, and document analysis. The findings reveal that conventional methods still dominate stevedoring activities, with limited utilization of modern techniques. Factors such as coordination among personnel and infrastructural limitations contribute to delays and inefficiencies. Comparatively, modern methods demonstrate higher productivity. Recommendations include the increased use of modern methods, infrastructure enhancements, improved coordination, and continuous evaluation and improvement. Implementing these recommendations is expected to improve stevedoring productivity in Tanjung Perak Port and optimize overall port operations.

Abstract:

The purpose of this paper is to discuss the safety of ship berthing operations in port. Based on the features of ship's berthing operations and relevant literature, the Safety Factors (SFs) of ship berthing at docks are first investigated. A Safety Index (SI) with a Fuzzy Analytic Hierarchy Process (AHP) model is then proposed to assess those SFs from port marine pilots, by which port managers and ship carriers may make policies to improve ship berthing safety. To validate the model, berthing operations at Kaohsiung Port in Taiwan were empirically investigated. The results indicate the main safety factors affecting ship berthing at port docks are: working concentration, the condition of mooring lines, emergency response, port policy of improving business and berth length. Based on those results, the theoretical and managerial implications for ship berthing safety at dock are finally discussed.

Abstract:

Efficient and timely delivery of goods is considered the most critical operations for a port, and their optimization is crucial for the success of businesses and economies. In the last years, The machine learning algorithms have demonstrated that are advantageous in improving port operations, and this by the prediction and optimization of various aspects of the supply chain. In this paper, we present a case study of the implementation of machine learning algorithms for the optimization of hydrocarbon operations at Tangier Med Port. We selected four popular machine learning algorithms and tested their effectiveness in predicting cargo volumes and optimizing hydrocarbon liquid storage. Our results showed that the random forest algorithm outperformed the other algorithms with an accuracy of over 90% in predicting cargo volumes and a significant improvement in hydrocarbon liquid storage efficiency. The implementation of the algorithm in the production environment conduced to a considerable reduction in turnaround times, productivity improvement, then it has increased customer satisfaction. Our study is to demonstrate the advantages of the machine learning algorithms to improve the port operations and to provide the valuable insights into their implementation in real time scenarios. As a future work, we can study on exploring the use of other machine learning algorithms and their integration with other technologies such as the use of the Internet of Things (IoT) to promise further port operation optimization

Abstract:

Background: To improve port productivity, safety, and sustainability, the use of information and communication technology is being promoted as a smart port. The utilization of a terminal operation system (TOS) is important for advanced port operations, and it is necessary to organize the issues and characteristics of the TOS. Methods: The characteristics of TOSs introduced in Japan and those widely introduced in Europe and Southeast Asia will be investigated and discussed according to the port management system in Japan. Results: Japanese TOSs are characterized by a lack of automated functions, such as ship loading plans, and by the fact that they are designed to allow the crane driver to select the order of operations, which may be attributed to a system wherein stakeholders are segmented and on-site decisions are emphasized. The promotion of smart ports in Japanese-style ports requires a system for information linkage between stakeholders. Conclusions: TOS capabilities for smart ports should be implemented according to the characteristics of port management in each region, and the studies conducted in this paper are useful in examining port system implementation strategies.

Abstract:

Port tugs are an important element in port activity and navigational safety issues. Port tugs ensure the safety of big ships while they are entering, manoeuvring, mooring and unmooring, and are of huge importance during other port operations. At the same time, optimizing the number of port tugs and tug bollard pull is also important from a port navigational safety and economic point of view. Calculation and evaluation methods of the optimal request for tugs bollard pull, in particular, port operations, are very important in order to guarantee the navigational safety of the port and ships during the main ship operations in the port. This article provides the number of requested port tugs and bollard pull calculation and evaluation methods on the basis of forces and moments acting on ships. On the basis of real ship voyages and manoeuvring at ports data as well as high accuracy simulators, theoretical methods were used, which were followed by our conclusions and recommendations, which can be used by port harbour masters and tug companies. Modern tugs have become an important element and integral part of modern port navigational safety. Such modern port tugs are also used for navigational safety and other important port functions and activities, such as fire protection and search and rescue operations. The optimal number and capacity evaluation of port tugs depending on port capacity and conditions are studied in this article.

Abstract:

Accidents at ports often lead to major accidents, disruption of operations and loss of productivity due to vacancies of workers at ports. In South Korea, laws requiring special attention to safety in port operations, such as the Serious Accident Punishment Act and the Special Port Safety Act, have been enacted and implemented, and social demands for port safety are increasing. Nevertheless, in terms of academic research, there is a lack of studies that consider the number of port disasters as a hazardous output among the various factors that determine the efficiency of ports. Therefore, this study analyzed the safety efficiency of South Korean state-managed trade ports from 2019 to 2023 considering the number of port casualties using the SBM-Undesirable window model. The results of the CCR analysis of the SBM-Undesirable window model show that Gunsan and Daesan ports maintain a high level of efficiency with low volatility, while Busan, Ulsan, and Yeosu-Gwangyang ports show a high level of efficiency with relatively high volatility. The results of the SBM-Undesirable window model BCC analysis showed that Busan Port, Masan Port, Gunsan-Daesan Port, Donghae-Mukho Port, and Donghae-Mukho Port maintained high levels of efficiency with low volatility, while Ulsan Port, Yeosu-Gwangyang Port, and Mokpo Port showed high levels of efficiency with relatively high volatility. Subsequently, the ports of Incheon, Pohang, and Pyeongtaek-Dangjin, where the dynamic safety efficiency of the ports was relatively low, adjusted the input variables, output variables, and hazardous output variables to establish a sustainable operation strategy.

Abstract:

Introduction. Seaports in a state’s economies are the main levers of economic development, investment generators, and innovation demand. Modern trade ports are open systems that are influenced by many factors. During the last decades of globalization and innovative technologies, an essential factor in the competitiveness of seaports, such as the stability of the functioning of Ukraine, is gaining relevance. The improvement of port management is driven by the urgent need to apply innovative strategies and methods to ensure the development and efficiency of the port industry due to the impact of many factors affecting the stability and growth of the port system. Aim and tasks. The aim of the study is to assess the influence of various factors on the consistency of the management system of the port industry. Result. An algorithm for forming generalized stability indicators for the functioning system of the port industry is proposed. Using an entropy approach to the management indicators of the development of the port industry functioning system showed an increase in the indicators of the ship operations group by 1.07% and cargo operations by 1.01%, a decrease in the financial group by 1.65%, and a port environment by 1.30%. The application of the established approach and the defined sequence of relevant calculations will allow ports to respond sensitively to violations of the stability of their system both at the industry and individual port levels and to find answers for each group of selected influential indicators for the finance group, the ship and cargo operations group, and the port environment. The main difference between the proposed approach and the existing ones is the calculation of the overall level of functioning of the port management system, which is based on the accumulation of the values of the relevant integral indicators for groups of indicators such as finance, ship-cargo operations, and port environment. Conclusions. The operation system of the port economy can be considered from the perspective of researching its various states, which are a consequence of the dynamics of the external environment. This allows us to use such a quality of entropy by considering the final nature of the management processes of the industry. This will help determine the nature of trends that can be considered in the future when forecasting the port industry’s development directions and when making relevant comparisons in the industry at the national and global levels.

Abstract:

The cornerstone of port production operations is ship handling, necessitating judicious allocation of diverse production resources to enhance the efficiency of loading and unloading operations. This paper introduces an optimisation method based on deep reinforcement learning to schedule berths and yards at a bulk cargo terminal. A Markov Decision Process model is formulated by analysing scheduling processes and unloading operations in bulk port imports business. The study presents an enhanced reinforcement learning algorithm called PS-D3QN (Prioritised Experience Replay and Softmax strategy-based Dueling Double Deep Q-Network), amalgamating the strengths of the Double DQN and Dueling DQN algorithms. The proposed solution is evaluated using actual port data and benchmarked against the other two algorithms mentioned in this paper. The numerical experiments and comparative analysis substantiate that the PS-D3QN algorithm significantly enhances the efficiency of berth and yard scheduling in bulk terminals, reduces the cost of port operation, and eliminates errors associated with manual scheduling. The algorithm presented in this paper can be tailored to address scheduling issues in the fields of production and manufacturing with suitable adjustments, including problems like the job shop scheduling problem and its extensions.

Abstract:

Turning ships in port turning basins is an important and responsible operation, mainly involving the ship itself and the port tugboats. Such operations involve many maneuvers that consume a lot of energy (fuel) and emit a lot of emissions. Turning basins in harbors and quay approaches are, in most cases, relatively shallow. This paper examines the turning of ships in port turning basins using harbor tugboats, the effect of shallow depth on ship turning, energy (fuel) consumption and the generation of emissions during such maneuvers of harbor tugboats. This paper presents the developed theoretical models, and the experimental results on theoretical models that were verified on real ships and using calibrated simulators. Discussions and conclusions were prepared on the basis of the research results. The use of the developed methodology makes it possible to increase shipping safety, optimize maneuvers and reduce energy (fuel) consumption when turning ships in the port and, at the same time, reduce the amount of fuel consumed by port tugboats and reduce the number of emissions of tugboats during such operations.

Abstract:

Port based freight movement planning is a complicated task that could be carried out efficiently to handle the cargo, optimally utilize the infrastructure and plan the future infrastructure requirements. The nature of activities at the port is dynamic with uncertainties ,since the operations are time bound, scholastic and probabilistic. As the huge capital is involved in port infrastructure, the inter-relationship between port activities need to be understood and a system model enveloping the relationship among the variables is much needed for optimal utilization of existing facilities and to predict the future infrastructure requirements. The conventional four step model approach for modeling the person trips would not effectively reflect the commercial scheduling constraint sand requirements of freight trips. This research work attempts to model the port operations, to assess the level of service of roads and gate operations as subsystems to understand the interdependencies between the variables and the impact on the port operations as a whole.

Abstract:

This research presents a comprehensive analysis of sustainable port operations in two countries, utilizing econometric models, including the stochastic frontier and Cobb–Douglas models, to examine critical elements such as the number of empty containers and vessel traffic. These factors, driven by globalization, significantly impact the environmental and social dynamics within port operations. By integrating these models, this study assesses efficiency and sustainability, addressing methodological gaps in existing research, particularly in the quantification and generalization of CO2 emissions. Findings indicate that, despite differences in port management and operations, CO2 levels can be estimated using operational variables without the need for complete CO2 traceability throughout the logistics chain. This study concludes by emphasizing the importance of incorporating international environmental standards into port operations and recommends the use of econometric models as tools for assessing and managing port sustainability effectively.

Abstract:

The Japanese government has set an overseas infrastructure deployment policy to involve Japanese companies in all upstream to downstream processes, that is, from project formation, procurement, and construction to operation and maintenance. Although Japanese companies have been hitherto involved in overseas port development through Official Development Assistance, their entry into overseas port operation projects has been limited, meaning the realization of the policy is not expected to be easy. This study thus examines the possibility of sustainable entry into overseas port operation markets by Japanese companies. Specifically, we review port governance in Japan, characteristics of the Japanese market in the global market, and the status of the participation of domestic terminal operators in Japan and overseas, and then identify the possibilities and methods of sustainable inclusion in the future overseas port operations by interviewing representative companies and the government. We finally provide future directions in terms of both increasing entry opportunities and improving the entry environment.

Abstract:

China's cruise industry has developed rapidly in the past ten years, and China's cruise port construction has flourished. A total of 20 cities along the coast of mainland China have built or planned to build cruise terminals. According to WTO estimates, China will gradually become the world's largest source country of cruise passengers and cruise travel consumers in the future. Due to different national conditions, the business model and development prospects of Chinese cruise ports are different from those of foreign ports. It requires finding the pioneers of domestic cruise ports to take the lead, providing advice on the development and operation of cruise ports. Dalian Cruise Port is actively formulating its cruise industry development plan, expanding the cruise port, and improving the supporting facilities in the cruise port area. Based on the characteristics of the operation of the Dalian cruise port, we use the gray model to make a vague prediction of the future development of the cruise port. It reflects the advanced operation mode of Dalian Port. This research systematically analyzed cruise port operations and maritime cruise transportation. Because the cruise port's business model and prospects are essential to the cruise port industry, China's cruise ports must learn more advanced operating models.

Abstract:

The paper analyzes hydrometeorological phenomena in the port of Chornomorsk. Changes in climatic conditions over the past 5 years have been identified. The most dangerous directions and speeds of winds, waves, which affect the operation of the port, have been determined. Analyzed the precipitation and the frequency of occurrence of various meteorological phenomena (thunderstorms, fogs, blizzards) in recent years. Conclusions were made on the unfavorable conditions of the port. Ensuring the safety of navigation during entry and exit from the port is one of the most pressing problems. Analysis of hydrometeorological conditions helps to reduce the number of accidents that occur due to ships grounding and bulkheads on the berth. Knowing the weather conditions in the port water area, you can ensure the safety of navigation. To compile a statistical analysis of the hydrometeorological characteristics in the port, a study of the logs of meteorological observations for every day over the past 10 years, as well as the cadastres of the seaports of Ukraine was carried out. The result of this analysis is the receipt of unfavorable factors that hinder the operation of the port in normal mode. It was also possible to establish the most unfavorable phenomena that limited the possibility of entering and leaving the port, as well as the months in which these phenomena are possible. Analysis of the parameters of the hydrometeorological situation allows us to conclude that the industrial activity of the port largely depends on the state of the weather and the sea. unfavorable meteorological phenomena reduce the efficiency of work and can pose a threat to the safety of their conduct. Various weather and sea phenomena affect port operations in different ways. The production activity of the port is largely dependent on the state of the weather and the sea, since unfavorable meteorological phenomena reduce the efficiency of work and can threaten the safety of their work. Various weather and sea phenomena affect port operations in different ways.

Abstract:

Because container shipping is the most important means of transportation for international trade, the integration of port–hinterland operations is critical to improve the performance of global supply chains. Information and communication technology (ICT) can assist port stakeholders in addressing bottlenecks and streamlining processes at the port–hinterland interface. However, ICT adoption is often hindered by uncertainties concerning expected gains. This paper shows that the adoption of well-established technologies for supply chain management—namely barcode and global positioning systems technology—can bring significant performance gains for the port–hinterland interface, as evidenced by increased container cycle time, utilization rates, and total throughput. In addition, results show the presence of diminishing returns when implementing multiple readers in the system. System dynamics and a unique database containing real data from the Hutchinson Terminal at the Port of Veracruz, Mexico—selected because it is one of the most important ports in the Americas—are used to show the benefits that both local (nodes) and global (supply chain) levels can obtain from ICT adoption. The results of this research will help to reduce uncertainty and incentivize ICT adoption by port stakeholders, particularly in developing countries where research is lagging. The model proposed here can be applied to any port to analyze the impact of ICT adoption and provide support for the decision making of port stakeholders.

Abstract:

Supply chain bottlenecks in port operations lead to significant delays and inefficiencies. Blockchain technology emerges as a viable solution, offering tamper-resistant ledgers, secure transactions, and automation capabilities. While considerable research on developing blockchain-based solutions currently exist, there is a lack of studies that specifically focus on optimizing port document management to speed up supply chain operations. In this paper, a supply-blockchain functional prototype for optimizing port operations using Hyperledger Fabric is introduced. In terms of core functionality, the prototype allows initiation of smart contract corresponding to functions such as creating and editing port-related documents, minimizing manual interventions and enhancing efficiency to reduce port congestion. Furthermore, it provides live tracking of completed events and transactions, facilitating transparency and streamlined oversight. The permissioned nature of Hyperledger Fabric ensures security and robust access controls, aligning well with sensitive port operations. Hyperledger Firefly and its connector framework was used as the middleware to facilitate blockchain integration and various functions of the prototype, while chaincode developed using Go language was used to package and deploy smart contracts. The supply-blockchain framework was used as the theoretical framework for prototype development, and agile project management was adopted to ensure timely completion. The results based on functional and performance testing demonstrate the prototype’s potential in alleviating port documentation bottlenecks and quickly delivering benefits to key stakeholders.

Abstract:

Ports are key pieces of infrastructure that enable the transportation of goods and passengers. Bays Port, Sydney NSW is located in close proximity to communities and balances the increased demand for Port facilities and services with community expectations, environmental requirements and regulatory approvals. For noise generated from Port activities at Bays Port, historically, individual port users have been required to monitor and evaluate noise under different environmental requirements and planning approvals, which can lead to inconsistent reporting, noise limits and regulation between operators and a lack of clarity for the community. Port Authority of NSW has implemented a first of its kind policy in Australia for the management of Port noise from both individual vessel and landside noise sources. To achieve these objectives, an automated directional noise monitoring system has been implemented to provide real-time measurement and analysis of noise contributions from vessel and landside activities. The system utilizes live data of individual vessel tracking locations, meteorology and an array of 6 direction microphones located around the port infrastructure. This information feeds into a live platform to facilitate management of port noise operations. This paper provides an overview of the Port Noise Policy and the use of unattended directional noise monitoring systems to meet the policy’s aims. Case studies are also provided to illustrate the benefits of real time monitoring systems in pro-actively managing port noise.

Abstract:

Port tugs bring large vessels into the port and take them out of the port, assist them during mooring and unmooring, move vessels from one mooring to another, tilt vessels, tow port barges, transshipment mechanisms, dredgers and other floating objects. Calculation and evaluation methods of the optimal request for tugs bollard pull port operations, are very important in order to guarantee the navigational safety of the port and ships during the main ship operations in the port. The most dangerous situations are situations of sudden failure of the power plant when maneuvering a vessel in the confined waters of ports, when tugboats become the only means of control that can prevent an accident. This is observed when the vessel moves in an area with hazardous sections of the waterway, calls into and out of the port, as well as when performing mooring operations. Line and / or port pilots, as well as tugs for escorting, escorting or when performing mooring operations of the vessel, are additionally involved in the process of navigating the vessel. In foreign ports, there are also very tense conditions in command management due to language barriers and the need for synergistic interaction of individual independent ship crews without prior preparation for a responsible mission. In this paper done a focus to improve tug possibilities and decrease navigational risks in port areas by method of balance handling forces. Such decrease in risks at ports is important issue to overcome, since the correct and proper usage of port tugs could highly improve the situation there. Keywords: tugs, emergency situation, port maneuvering, energy balance of the control force.

Abstract:

Abstract Determination of efficiency and optimization harbour tug fleet is based on simulation of fleet work and usage for this the methods of ship dynamics and probability theory. Visiting the port transport vessels of possible types is considered as random stream of given intensity. This stream is distributed over the berths. Productivities of berths are given random variables. Random variables are also characteristics of weather conditions in the harbour basin. Tug fleet is represented by the collection of existing port tugs of different types. Work of tugs is determined by operations of approaching to ships, escorting theirs in the near-port waters, posting on the approach channels, transportation within the port waters, berthing, unberthing and going out the ship from the port with the repetition of functioning operations in reverse order. Selection of tugs to service the next arriving or departing ship is dependent from the intensity of the current weather conditions in the port and busyness of tugs in operations with other ships. Work fleet is considered on the conditional time interval of one year. In this time the efficiency of the tug fleet is defined by economic indexes of fulfilment of all towing operations and operations on maintenance tugs. Optimization of the fleet composition is carried out according to the criteria required minimum total bollard pull, low cost and high profit. Based on performed research a program for calculating the efficiency and optimization of the port towing fleet is composed. The program can be adapted to any port with whatever types of tugs.
