Multifrequency traverse-scan sonar for monitoring of marine bioresources in shallow water on technologies of nonlinear acoustics (MTSS)

Multifrequency traverse-scan sonar for monitoring marine bioresources in shallow water using nonlinear acoustics technologies (MTSS) is intended for horizontal location of fish accumulations and single fishes, monitoring of marine bioresources in adverse search and fishing conditions of shallow water.

MTSS is intended for consumers conducting research (search, detection, monitoring, evaluation) and catch of marine bioresources in inland waters and on the offshore shelf.

Currently, only echo sounders (vertical location) are used to detect and monitor bioresources in shallow water. The scanned area of the water space in the echo sounders is very limited. At shallow depths, when the vessel moves, the “scaring effect” has a significant effect on fish behavior. Devices of horizontal location (“conventional” sonars) with a large field of scan are extremely inefficient due to reverberation and multiple reflections of acoustic signals from the bottom and the surface.

Multi-channel electro-prospecting streamer for marine engineering surveys

The purpose of the development is to create a comprehensive technology of effective marine engineering surveys to minimize the risks in construction and operation of technical structures on the shelf: drilling platforms, gas pipelines, etc., which is achieved by studying the bottom sediment with a set of geophysical methods as well as by monitoring these facilities during the period of operation.

The result of the use of these technologies will be creation of an integrated geological and geophysical cross-section down to a depth of 500 meters. In association with seismic and echolocation data, the use of electrical exploration technologies will allow to identify such geo-electric heterogeneities in the upper part of the cross-section as gas pockets, gas hydrates, zones of permafrost and fault zones.

Circular thermoelectric generating module

The creation of remote energy sources is a resource-intensive and complex task. There are important questions of necessity to provide long-term operation, reliability and absence of vibrations are sharply raised. Often, such energy sources are discarded in favor of simpler alternatives because of the increased cost of generated energy. But, thanks to the rapid development of semiconductor technologies and an increase in the efficiency of thermoelectric processes, new opportunities have appeared to increase the efficiency of remote systems.

The goal of the project is to create a reliable source of energy for remote marine infrastructure facilities and marine autonomous underwater vehicles. This project implements an innovative device approach of a remote electric power source. Reliability, safety, environmental cleanliness in combination with compact dimensions and high efficiency are ensured. (more…)

Simulator complex – TRAWL

The simulator complex has been designed to solve a wide range of tasks related to numerical simulations, design and management of the trawl complex, maintenance of a document database, design and mathematical models of trawl complex elements, training journals and programmes, topology of fishing grounds (maps of fishing areas), commercial schedule (command placement) and access to the database.

Electronic sextant

The essence and content of the project, the available groundwork. The analysis of the technical means installed on the vessels providing the possibility of obtaining the observable coordinates of the ship’s position allows us to conclude that the only backup (independent of the presence of a radio signal and power supply) is the astronomical way of determining the observable coordinates of the ship’s position when navigating on the high seas.

The improvement of the procedure of obtaining the astronomical observable position of the vessel is associated with the improvement of the instrument intended for measuring the observable navigation parameter-the height of the luminary-the navigation sextant. Any action to improve the design of sextant stopped in the 70-80s of the last century, and this device does not meet the state of the art and scientific achievements. (more…)
