The analysis of "Vanino - Kholmsk" ferry line operation is made, need of replacement of existing ferries is designated. On the basis of researches Marine Engineering Bureau created new generation high artic class railway-car-passenger ferry of CNF11CPD project. In comparison with existing ferries the new Marine Engineering Bureau project provides improve cargo capacity, operation without weather restrictions and at hard ice conditions, can effect independent mooring operations (several times a day) without tug assistance, astern movement through constrained port of Kholmsk. Service speed of 18 knots and 2 hours for loading operations in each of port allow makes round voyage per day. Forward part of the hull structure are designed on higher ice category (ARC 7). It allows to provide independent operation in heavy ice conditions of port Vanino.

Ocean Engineering | Year: 2014

A review of the recent progress made regarding ocean environmental data and models with uncertainties in focus is given in the perspective of marine structures' design and operations. Uncertainties of wind, waves, current, sea water level and ice data and models are discussed and recent achievements leading to improvement of their accuracy are addressed. The study includes mathematical, probabilistic, empirical and statistical models. Particular attention is given to rogue waves. Challenges related to wind data and models due to the increase of offshore wind energy installations are presented focusing on wind forecast, information about the wind profile and extreme wind events. Attention is also given to ice which is of particular importance due to the projected climate changes opening new opportunities in the Arctic regions for the marine industry. Impacts of improved accuracy of environmental description on design and operations of ships and offshore structures are highlighted. © 2014 Elsevier Ltd. All rights reserved.


The article presents a description and physical evaluation of a method of flaw detection of solid structures, for example, walls, pillars, and substructures, made of refractory materials and brick masonry using as an example an investigation of concrete structures. Using the method it is possible to perform flaw detection of concrete with different fillers, including porous fillers, for example, concrete claydite. This brings the subject of flaw detection of concrete close to that of flaw detection of brick masonry and structures made of refractory materials. The method is based on local excitation of standing waves across a wall by means of multiple shock pulses. The experimental data obtained confirm that standing waves are not excited once there is a definite number of defects present, i.e., a process of complete damping of the waves occurs. © 2015 Springer Science+Business Media New York

In this paper, a digital image watermarking algorithm based on chaos and Fresnel transform is proposed. The original image is transformed into Fresnel diffraction plane by distance parameter, and watermark information is embedded in its amplitude spectrum after scrambled by chaotic sequence. The watermark information can be extracted without original image, and there is little influence on the original image after embedding. Chaotic scrambling can encrypt watermark information, and Fresnel transform can provide different diffraction planes with different parameters, so attackers couldn't get right watermark information without knowing the parameters in these two processes. During the experiments, the algorithm is also robust against various common attacks, such as filtering, adding noise, JPEG compression and crop and so on. Experimental results show that this watermarking algorithm can provide enough invisibility, security and robustness. © 2012 IEEE.

This article contains an analysis of the major problem related to the development of a power plant based on fuel cells for diesel-electric submarines - hydrogen storage/production. Various options of hydrogen storage/production have been studied. The analysis shows that hydrogen production based on hydrolysis of aluminium onboard the submarine seems to be promising. The article describes a block diagram of the developed plant for hydrogen production via hydrolysis of aluminium, and the test results of the full-scale prototype. The tests confirmed the possibility to create an efficient ship system for continuous hydrogen production based on hydrolysis of coarse-dispersed aluminium powder. As a result, hydrogen can be used in fuel cells of any type without purification, and the reaction product, that is boehmite, is commercially profitable. © 2010 Professor T. Nejat Veziroglu.

A new generation of railway-car-passenger ferry for the line Vanino-Kholmsk. In comparison with existing ferries the new Marine Engineering Bureau project provides improve cargo capacity, operation without weather restrictions and at hard ice conditions, can effect independent mooring operations (several times a day) without tug assistance, astern movement through constrained port of Kholmsk. Service speed of 18 knots and 2 hours for loading operations in each of port allow makes round voyage per day. The new concept should carry up to 150 passengers; she can carry dangerous cargoes. Ice-going capability of the new ferry on moving ahead in ice thickness 1.48 m at speed of 3 knots, 1.04 m at 6 knots, and moving astern in ice thickness 0.85 m at speed of 1.5 knots. Forward part of the hull structure is designed on higher ice category (ARC 7). ) allowing it to provide independent operation in the heavy ice conditions of port Vanino. © 2015: The Royal Institution of Naval Architects.

Basic designing principles of dry-cargo vessels and tankers hulls of river-sea going type that have been built during 2001-2010 are considered. It is shown that all these vessels are designed with fully use of locks dimensions of internal water-ways, maximum possible block coefficient with providing best propulsion qualities, increased tonnage with minimum possible depth; increased controllability in constrained conditions and in shallow water; grounded operating reliability of hull construction with optimum specific quantity of hull metal. © 2014 Taylor & Francis Group, London.

Importance of transport connection in the Black Sea region is shown. Characteristics of existing Black Sea shipping companies’ cargo and cargo-passenger ferries are provided and analysed. It is shown that the mean age of Black Sea ferries is of 28 years and these vessels should be scrapped in near future. To replace outdated fleet Marine Engineering Bureau (MEB) created new generation parametrical line-up of Black Sea cargo and cargo-passenger ferries. Main characteristics of new parametrical line-up of ferries are grounded. Some of these ferries have already been built. Besides modern concepts of cargo and cargo-passenger ferries for different Black Sea lines with good economic efficiency are shown. © 2015 Taylor and Francis Group.

Dimensional line-up of Russian modern river-sea navigation tankers and combined vessels working on river ports is grounded. Accepting of main particulars for river-sea vessels is defined by way restrictions and strategy of future shipowner. As usually the most interesting decisions for tankers are those that provide the maximal cargo capacity for set conditions. General neediness for the river-sea “Volgo-Don Max” type tankers is estimated as 100-120 ones as minimum. © 2015 Taylor and Francis Group.
