On influence of hydrometeorological conditions on trawl system movement

This paper considers the problem dealing with the stream and wind influence on the "ship-trawl" system. The system parameters change constantly during curvilinear movement, i.e. the movement is not stationary when it is windy. The constancy of the system parameters may be maintained only by means of the ship’s automatic regulating propulsion. It is found out that the ship’s drifting angle is the largest one at the adverse wind and the largest angle of shifting of rudder occurs at the astern cross wind.

Aspects of minor hydro-electric engineering in Murmansk and the Kola Peninsula

The paper considers the possibilities of using small waterways (streams, rivers) with different energy potentials for power supply in our region. The numerical data about the regional energetics have proved perspectives of minor hydro-electric engineering in the region. The rough estimate and cost analysis, construction and recoupment period have been given as well. The attention has been paid to the fact that minor hydroelectric power stations do not affect local ecological situation and spawning areas. The development of minor hydro-electric engineering has been proved to make a positive contribution to power supply of small towns of the Kola Peninsula
