Biofouling as one of the Factors of Sustainable Development of Shipbuilding

Sea transportation is one of the cheapest and most widespread types of cargo transportation, and the process of fouling of the vessel’s hull has an extremely negative impact on its maneuverability and running characteristics. This leads to excessive consumption of fuel, an increase in the cost of delivery of goods and environmental risks. Namely, when additional fuel is burned, the emission of the greenhouse gas CO2 increases. Considering the accompanying environmental risks in the long-term planning of the shipbuilding industry will ensure the sustainability of its development. In the study we suggest a simple way to assess quantitatively the development strategy of shipbuilding from the point of view of the accompanying economic and environmental consequences by constructing a matrix model for the industry development. The matrix model was applied to the Strategy for Development of the Shipbuilding Industry in Russia until 2035. In the future, on the basis of the offered model, it is possible to develop optimal environmentally neutral scenarios for shipbuilding development.

Long-Term Development of Russian Shipbuilding in View of Defense Sector Diversification Processes: Model and Forecast

The article reconstructs and analyzes trends in the development of Russian shipbuilding in 2011–2019 and assesses the long-term development potential of the shipbuilding industry in 2020–2035, with due consideration of a scenario of fast-tracking the reequipment of the technological and industrial base of the industry. The analysis showed that shipbuilding development was at its most effective in 2014–2017, and in 2018–2019 the trend changed for the worse due to changes in implementation timelines of a number of large military contracts, which lead to reduced efficiency of production. If current trends continue, the target level of shipbuilding industry growth specified in the Strategy of Shipbuilding Industry Development for the period up to 2035 cannot be achieved. Support measures need to be reoriented to proactive modernization of the technological and industrial base of the industry, which includes increasing the number of shipbuilding yards designed for construction of large vessels.

To the Issue of the Methodology of Formation of Shipbuilding Programs in Russia

The presented study addresses the need to change approaches to the formation of long-term shipbuilding programs in the Russian Federation and determines the place of such programs in the system of strategic management of the national economy.Aim. The study identifies efficient approaches to the formation of long-term shipbuilding programs in Russia with allowance for international experience and current political and economic conditions.Tasks. The authors analyze the existing methodological framework for the formation of shipbuilding programs in the Russian Federation; examine the shipbuilding development experience of South Korea, China, the US, and Ukraine; address the issue of improving the investment climate in the shipbuilding industry by changing the institutional conditions in closely related industries.Methods. This study’s scientific methodology is based on using general scientific methods of cognition, a systems approach to the problem, and comprehensive consideration of the issues of formation of industry programs with allowance for the specific features of shipbuilding.Results. Over the past decades, shipbuilding programs in the Russian Federation have been formed according to a methodological framework of questionable depth and insufficient sophistication. Successful development of shipbuilding in the world’s leading countries is largely due to the achievement of the required level of competence and technological advancement accumulated through the development of the domestic market, which is impossible without active state participation. Based on the analysis of positive and negative shipbuilding development experience of different countries and current trends in the Russian shipbuilding industry, it is possible to conclude that the success of shipbuilding development largely depends on the rules (institutional conditions) established by the state.Conclusions. The efficiency of investment processes in the industry can be improved by integrating the shipbuilding development program into a global program for the development of the marine economic complexes of the Russian Federation.

Shipbuilding in the Aral Sea and the Amu Darya River

This article is focused on the history of the emergence and development of shipbuilding in the Khorezm oasis in the 19th and 20th centuries. The history of Butakov's study of the Aral Sea and the discovery of sea routes in Amu Darya river has a two-hundred-year period. During this time, the navy and the seafaring reached a high level and almost ended. During this period, the major part of cargo transported to the Khorezm oasis by ships was a huge flotilla in this area. The deterioration of the ecological situation, the extreme degradation of the river and the complication of ships, the efficiency of rail, automobile, airfreight and passenger transport - all led to the limitation of ships' movement on the rivers of Central Asia.

Constraint Theory Approach Analysis of the Nigerian Shipbuilding Industry

Abstract Nigeria has been unable to develop a viable ship building industry over the years notwithstanding several efforts of government at achieving that. The study aimed to identify and determine the principal component constraints to ship building development in Nigeria. Adopting the theory of constraint approach, survey research design was used in which primary data were obtained from questionnaire responses from employees and management staff of shipyards in the ship building clusters in Lagos, Port-Harcourt and Warri. The data collected were analyzed using principal component factor analysis, analysis of variance and pie-chart. It was found that the principal component constraints to the development of the ship building sector in Nigeria include financial constraint with Eigen value of 31.23%, infrastructural constraint with Eigenvalue of 26.35% and poor skill and technical know-how with Eigen value of 16.23%. This implies that financial constraints, poor skill and lack of technical know-how and infrastructural constraints contribute a cumulative Eigen value of 74.259% and thus constitute the dominant constraints impeding the performance of ship yards, ship building and repair sector in Nigeria. Development of national ship building and dry-docking funding scheme, ship building research and training center among other things were recommended.

A Short Communication for Shipbuilding Industry in Vietnam

According to Shipbuilding Industry Corporation (SBIC), in 2017, shipbuilding value reached more than VND 3,071 billion, equal to 69% of the plan. Other fields have increased significantly, such as: Ship repair reached VND 488.3 billion, equal to 125% of the plan; supporting industry reached VND 264.5 billion, equal to 123% of the plan. Although shipbuilding has not reached the plan, but looking back on the period from 2008 to now, this field is always in a situation of hardship and bottomless decline because of lack of jobs, these are quite satisfactory numbers. The cause of the decline is due to the world shipping and shipbuilding industry has experienced an extremely difficult period due to the heavy influence of the world economic crisis from 2008 up to now. The Vietnamese shipbuilding and shipping industry is also not out of that situation. For the shipbuilding industry to develop, specific policies, with specific support addresses, are needed, which are well-designed and visionary shipbuilding development programs.

History of shipbuilding in the South of the Ukrainian SSR in 1945–1991: theoretical and methodological principles of the research

Coverage of the past requires, first of all, researcher’s understanding of the essence of the historical knowledge, skills on the principles of epistemology and historical science, using necessary scientific methods, objective reconstruction of the course of events. That is, he must know the ways of research and the ways of learning the past, in other words, he must be knowledgeable about the methodology of the historical science. The modern methodology of history is characterized by diverse, sometimes opposite approaches to the study of the historical past due to, first of all, differences in historians’ worldview and their understanding of a historical reality. All this leads to the formation of a polyvariant, pluralistic, nonlinear methodology. Starting a research, a historian must understand what theoretical principles he will rely on, from which point of view he will consider events and phenomena. At the same time, each researcher has the right to choose his own methodological foundations for comprehension of historical existence, to use logical constructions, principles and methods which, in his opinion, are most optimal for solving a specific scientific problem. Investigating the development of shipbuilding in the South of Ukraine in 1945–1991, the author supports the dialectical understanding of history, believing that dialectics captures (reflects) the most characteristic features of the development. Choosing dialectics and the theory of modernization as the main philosophical approaches, the principles of objectivity, historicism, systematicity, pluralism and modern methodological tools makes it possible to solve the tasks and achieve the goal of a concrete historical research of the development of shipbuilding in the South of Ukraine in 1945–1991.

In order to develop the Russian industries, federal authorities have taken steps to implement the program approach. At the same time, among a wide variety of industries, the shipbuilding industry is recognized as one of the priority. The article identifies the trends in development of shipbuilding industry in Russia and abroad - investment activity. There has been considered the state, problems and priority directions of development of shipbuilding in the context of the investment policy implemented within the framework of the existing program of the Russian Federation for the development of shipbuilding. The direct and indirect influence of investments on the branches of the economy is analyzed, examples of attracting investments in the context of free placement of investments or limiting their presence in a country are given. The results of the state policy in the field of shipbuilding have been considered.The special features of shipbuilding production, the instability of the external environment have determined the specifics of investment in the industry. The analysis of investment mechanisms into the shipbuilding industry has been made on the example of tools of the state support at the level of the entities of the Russian Federation. The characteristics of the form of state support for special economic zone on the example of the “Lotos” economic zone (the Astrakhan region) have been considered. The economic zone in the Astrakhan region, due its geopolitical location and economic potential, will base on enterprises of shipbuilding complex; in this connection, there have been formulated conditions for characterizing efficiency of the special economic zone development. There have been shown the results of the general economic effect obtained due to investments in the region.

Critical study on the thermal-structural characteristics of worktable assembly of a dry hobbing machine

Dry hobbing machine is a kind of specialized machine tool to manufacture high-quality small-module gears. With the development of shipbuilding, automobile, and wind power industries, higher request on the dry gear hobbing accuracy is called. The thermal-induced error, which accounts for 50–70% of machining error, needs to be reduced more efficiently. Hence, in-depth investigation on the thermal-structural characteristics of the dry hobbing machine is indispensable. In this paper, thermal-structural coupling numerical simulations were conducted to investigate the heat transfer process as well as thermal-induced deformation of the worktable of a YDE3120CNC gear hobbing machine in the large-volume gear production. New equations were used here to describe the convection heat transfer happened on the worktable assembly. Verifying test results proved the feasibility of the newly proposed numerical method. Following numerical simulation, results indicated that during the gear hobbing process, the highest surface temperature of the worktable assembly appeared at the top surface of the fixture, and corresponding thermal-induced deformation reached the maximum of 49.9 μm. Besides, in a large-volume production, the worktable assembly would attain thermal equilibrium in 15,000 s. Hence, the assumption widely used in previous studies on gear hobbing machines that the worktable assembly could be treated as an ideal solid without any thermal deformation is wrong. The thermal-induced deformation of the worktable assembly should be considered in the subsequent development of the thermal error compensation system.

Measuring Severity of Downtime Influence Factors to Naval Ship Operational Availability: A Delphi Study

Rapid development of shipbuilding and ship repair industry in recent years has been increasingly transforming the way organizations apply the long term strategic thinking of “cradle to grave” maintenance approach in order to maximize their growth in a dynamic marine industry. With increased ship complexity, size and revolutionary design, organizations strive to balance ideal maintenance philosophies against on-going efforts of cost reduction whilst maintaining high availability of vessels. Despite aspiration and efforts to improve the ship availability, the Royal Malaysian Navy [RMN] vessels which are currently maintained under the In Service Support [ISS] Contracts are hardly tackling the human and equipment related aspects due to limited knowledge and available data on ship Downtime Influence Factors [DIFs]. The current research carried out an explorative study across various engineering disciplines to generate RMN ship maintenance DIFs and their severity measures via a 3-Stage Modified Delphi approach. 30 Experts experienced in daily implementation of naval ship maintenance contracts were involved. In the first stage, Focus Group Discussions [FGDs] amongst Experts were conducted to produce the DIFs, followed by questionnaire distribution to measure the severity of the DIFs in the second stage. In the third stage, the Severe DIFs were confirmed and ranked based on a Risk Assessment method. The study revealed 50 DIFs to RMN ship availability and deduced the top 15 Severe DIFs pinpointing the key problem areas to prioritize efforts in improving RMN ship availability.

Research Report: Thonis-Heracleion, Emporion of Egypt, Recent Discoveries and Research Perspectives: The Shipwrecks

The European Institute of Underwater Archaeology’s work on the city of Thonis-Heracleion, which is located in the submerged Canopic region in the west of the Egyptian Nile Delta, has revealed this ancient port-city in all of its detail. From the 8th century BCE, this town was the custom and border post and the emporion that controlled access to the Canopic channel, traded with the Greek regions, and supervised foreign ships. This paper will highlight the discovery of over 60 shipwrecks, dating from the 6th to the 2nd centuries BCE, which demonstrate the intense maritime and fluvial activity in this coastal region. Each shipwreck was radiocarbon dated and a paleobotanical examination of its structural timbers was carried out in order to assess the wood species used in the construction of the vessels. These data constitute an exceptional source of primary evidence to pursue investigations of the development of shipbuilding in the eastern Mediterranean, and of maritime trade and regional connectivity and finally on the interaction between human society/topography of the town and the natural environment.
