GENERIC APPROACH TO ASSESSMENT OF NAVIGATIONAL RELIABILITY

(Download article in PDF)
Abstract

This paper presents the generic approach to the assessment of the navigational reliability in the specific sea way. This approach combines two methods that are usually used when studying the safety at sea problem: analytical and statistical ones. The expressions are obtained that may be used for calculating the probabilities of the collision and grounding.

Keywords

vessel traffic flow, safety at sea, navigational reliability, probability of a collision, probability of a grounding, random value, distribution function, density.

EVALUATION OFALLOWANCE TIME FOR COMMENCEMENT OF THE CLOSE QUARTERS AVOIDANCE MANOEUVRE

(Download article in PDF)
Abstract

While making the decision for any action to avoid close quarters situation the navigator must evaluate the manoeuvrability of the vessel for the commencement of the manoeuvre. Very simple and convenient methods recommended for the alteration course alone and alteration speed alone manoeuvres explained with the illustrations. The algorithms and the equations systems developed for obtaining the results of this article may be used for calculation of close quarters avoidance manoeuvre as in the operational ARPA and VTS systems as in the developing ones.

Keywords

allowance time, close quarters avoidance, avoiding collision, safety maneuver calculation, vessel traffic management

CALCULATING WHEEL-OVER POINT

(Download article in PDF)
Abstract

The article consists of two parts. The first one presents a ship turning method in restricted waters that based on calculating the wheel-over point. The second part presents the method of ship’s turning in shallow waters that taking into account the increasing radius of turning due to increase of resistance of water and large water masses.

Keywords

ship, turning, radius of circulation, wheel-over point, turning radius, shallow waters, restricted water maneuvers.

SEA-GOING ALL-TERRAIN VEHICLES FOR EXPLORATION AND DEVELOPMENT OFARCTIC AND ASIA-PACIFIC COAST

(Download article in PDF)
Abstract

The use of versatile sea-going ATVs utilizing inflatable tracks (ATV-ITM) is rational for unloading cargo on unequipped shore as well as for transport-technological operations in support of coastal and continental shelf exploration and developmentn, including coastal fishery and aquaculture. The advantages of this ATVclass are its low ground impact which is important for protecting sensitive tundra soil in summer, and energy efficiency in high sea states. ATV-ITMs are efficient in rough terrain, ice, snow and in the swamps; the new motion principle ensures reliable operation of vehicles in a wide range of adverse weather conditions both in the Arctic and the tropics.

Keywords

sea-going all-terrain vehicle, inflatable track motion, air balloon tracks, amphibious craft, TSVG-60.

MODELING OF THE UNDERWATER AIRFRAME - GLIDER

(Download article in PDF)
Abstract

The article shows opportunity to calculate and develop an underwater glider as alternative to the classic one, which would be less complicated and less time consuming in construction. To create the model of the device the author has developed a special method of identification system. The model of the underwater glider is developed in order to research the mechanism of buoyancy control and dynamics of the vehicle movements especially in shallow waters.

Keywords

underwater glider, System Identification Theory, dynamic angles, glider masses identification, buoyancy control, autonomous underwater vehicle.

OPTIMIZATION OF HARD FORMALIZED PROCESSES USING FUZZY NEURAL MODEL

(Download article in PDF)
Abstract

The proposed modeling method of hard formalized processes regards not only qualitative data, but attribute (descriptive) as well as fuzzy defined non-formalized criterion & their connections. The model is developed for further process exploration with its behavioral forecasting and operational optimization. The method is based on fuzzy neuron nets technology. The operational optimization method is shown with factor analysis.

Keywords

intellectual controlling systems, data system, modeling, neural network technologies, fuzzy logic.
