LONG-TERM FORECAST OF THE POSITION OF THE ICE EDGE IN THE FAR EASTERN SEAS

Abstract

The study of ice condition in the Far-Eastern seas includes the following characteristics: formation; development and destruction of the ice; the ice period duration; the changes in maritime ice cover; ice concentration; the age types, forms, thickness of the ice; the presence of ice hummocks and snow cover; compression and rarefaction; landfast ice and ice drift. Since the end of 1970s the specialists in FERHRI are actively working on the development of methods for these characteristics.

There is a need for deep consideration of ice characteristics while performing practical and research tasks in water areas therefore it is desirable to improve the existing methods of ice research and long-term forecasting and to look for new ones, for example to expand the use of computer modeling. Since 2005 FERHRI (Department of long-term forecasts) experts are working in this direction, in order, for instance, to make forecasts for remote periods (more than 6 months) [1-5, 16]. Much of the accumulated positive experience has been used by the authors in this article.

This article presents the results of research work on the creation of new method of long-term forecasting of the position of the ice edge in the Far Eastern seas.

It is known that during the month the position of the ice edge may vary considerably. But even the picture of the average position of the ice edge during the ice period may allow to better plan their business activities on the seas.

Keywords

long-term forecast, ice edge, ice cover, predictors, accuracy of forecasts, ice regime of the sea, Sea of Okhotsk, Sea of Japan

THE USE OF FUZZY NEURAL NETWORK TECHNOLOGY FOR MANAGING TRANSPORT AND LOGISTICS PROCESSES IN THE ARCTIC

Abstract

The article presents the background and reasons for introducing the automated information control systems for transport and logistics processes basing on fuzzy neural network technology. The use of such systems is feasible for the components of maritime transport control systems in which the reliability, timeliness and regularity of delivery of goods cannot be guaranteed due to the fuzziness of the initial information. The Arctic meets these criteria due to its severe and unpredictably changing weather and ice conditions, communication problems and insufficient hydrographic support. It is proposed to apply this method to create a vessel / cargo traffic management system along the Northern Sea Route. Such system can be a powerful tool for planning and operational control on condition that maximum number of input parameters is assessed and that highly skilled experts with a real hands-on experience in the Arctic are engaged in its development.

BIONIC CONTROL OF THE ELECTROMECHANICAL DEVICE AND POSSIBILITY OF ITS IMPLEMENTATION IN SHIPBUILDING AND SHIP REPAIR INDUSTRY

Abstract

Mechanization of all production elements is the key to increasing its efficiency. Especially it is essential for labor intensive nature of the shipbuilding industry. The system allows mechanization of manual labor requiring physical efforts. Apparently, there are some disadvantages of using mechanisms with limited mobility. Specially designed carcass would allow its operator to manipulate with weight equal or exceeding the weight of the carcass via hydraulic actuators and other associated systems. Apart from production the system can be used to perform the other tasks when mobility and strength are required.

Keywords

bioelectric control, EMG signal (Electromyography), surface electrodes, myographic sensor, shipbuilding, ship repair industry.

THE PATTERN OF THE NAMES OF THE SEA IN THE MASS MEDIA AND ITS PROPAGATION APECTS: A CASE OF THE SEA BETWEEN KOREA AND JAPAN IN THE FRANCOPHONE NEWSPAPERS AND BROADCASTERS

Abstract

The purpose of this study was to investigate the names used in the newspapers and broadcasters in Francophone countries except France by analyzing the newspaper articles and broadcast contents, and to illuminate how the names of the East Sea produced in France, and the discourse about the names was diffused in Francophone countries and what kind of influence they have in those countries.

This paper analyzed the current usage of the names of the East Sea, decision making process about the names, and diffusion process of the names from France to Francophone countries by studying the major news media in Francophone countries. This study selected Algeria in North Africa, Belgium and Luxembourg in West Europe and Quebec in Canada as the research areas. To find out the names of the East Sea used in the representative newspapers and broadcasters in research countries, this study collated the newspaper articles and broadcast contents, distinguished features by each country based on this, and identified the interconnectivity by comparing them with France. Building on this basic study, the principles were examined which were applied when map or designation managers of the newspapers and broadcasters through the interview with them. This paper focused on the pattern of the names in the Francophone countries, connectivity with France, and the channels of geographic information from France to the Francophone countries.

Today, it is widely known that Korea and Japan have engaged in a delicate diplomatic warfare around the world for the names of the East Sea, and many map-making agents tend to evade this sensitive issue.

As a result, while Algeria in North Africa and Luxembourg are showing inhospitality to the name of East Sea, Belgium and Quebec are taking a flexible attitude toward the name. Every Francophone countries are provided with press releases from AFP in France. The result shows that some media stick to the name ‘Sea of Japan’, though others demonstrate a will to use simultaneously two names.

PREVENTION OF SHIPS COLLISION IN EXCESSIVE PROXIMITY ZONE USING THE THEORY OF FUZZY SETS

Abstract

The model of preventing collisions of ships using the fuzzy set theory is described. The presented model consists of four input variables such as bearing, course of own ship and target ship, speed of target ship, and one output variable - change of own ship course. The procedure of preparing rule base of fuzzy productions comprising 525 rules is shown. A maneuvering board was used for the formation of each rule.

Keywords

bearing, own ship course, target ship course, maneuvering board, rules of preventing ships collisions at sea, fuzzy sets, linguistic variable

THE ARCTIC IS BECOMING CLOSER…

Abstract

The development of Northern territories requires the using of modern vessels of active ice navigation powered by electric propulsion equipment. The main features that contributed to the use of electric propulsion are: excellent thrust, high maneuverability, good adaptability to various conditions of navigation. In the Soviet Union, the icebreaker fleet in the Far East basin consisted of up to 40 electric propulsion icebreakers and vessels of high Arctic class capable of active ice navigation.Then the number of them lessened due to which the transportation of goods to the North began to decline.

The situation began to change when the newest vessels powered by electric propulsion (icebreakers, tankers, gas-carriers, container ships) started operations in the Far Eastern basin. All this takes place within the framework of state programs.

The specialists for electric propulsion vessels are trained in several Russian universities, including Admiral Nevelskoy Maritime State University.
