    Gas monitoring instruments and systems for compressed breathing air

    Compressed breathing air is subject to strict limits of harmful contaminants defined in European standard EN 12021 and various defence standards such as DEF STAN 68-284 issue 3. The testing interval of breathing air compressors and associated equipment is 3 months and gases tested include carbon monoxide, carbon dioxide and oil vapour defined as hexane and heavier hydrocarbons. EN 12021 covers underwater applications including self-contained open circuit compressed gas breathing (SCUBA) and compressed gas line breathing (hard-helmet diving), respiratory equipment used on ground for escaping from toxic atmospheres and for working in contaminated atmospheres. It also covers breathing gas for hyperbaric operations and synthetic air. While EN 12021 does not cover aerospace applications, the British MOD publication DEF STAN 68-284 and its counterparts in other countries cover also the breathing gases used in aviation.

    WEDA Underwater cleaning robots in lagoons and large fountains

    The new Weda YT-5000 with a five (5) meter wide suction nozzler speeds up the cleaning process considerably. Estimated cleaning speed is up to 3000 sq. meters/hour. The cleaner removes efficiently bottom sedimentation (sand, algae etc.) from the bottom surface and pumps it to a selected discharge point (filter, waste etc).

    Multiparameter Monitoring for the Offshore Oil & Gas Industry

     Meeting the demands of small ROV’s to work class vehicles in the offshore oil & gas industry, Valeport have a range of sensors and probes to measure the physical parameters vital to safe operation.  From sensors to aid operation of the vehicle to probes for data input into metrology and construction operations, our “industry standard” packages are designed and built to perform.

    AUV requirements can mean provision of complete housed instruments or OEM style for users own interface.  Our small, low power, accurate and robust sensors will aid AUV manufacturers and users to get the data required.

  • Example of GPR application on fresh water reservoir

    GPR exploration of fresh water reservoirs allows user to examine in details the bottom. The important feature of GPR use that is to be mentioned - it can examine the structure of the bottom. I.e. there is possible to find underwater items located inside the bottom stratum. Also GPR can provide an information about the thickness of bottom silt or bottom ground, and its volume structure. The same exploration is very problematic if made by other means. In the summer 2012 VIY3-300 GPR was examined as sub-bottom profiler. The tests were made in Kyiv, Ukraine. GPR was placed in a plastic tub and moved across the surface of the fresh water lake. The survey window number of 166 ns corresponds to the depth of 2.7 meters. The signal reflected from the bottom is clearly visible on the profile. Compensation of the signal attenuation along increasing depth reached 60 dB. That indicates the water condition in an urban area.

  • Ground Penetrating Radars (GPR) for Fresh Water Reservoirs Eploring

    In hydrobiology GPR also find its applications: fresh water reservoir bottom structure. find items lying on the reservoir’s bottom and inside bottom sediment. measure of peat and other bottom sediments thickness . search for underwater piping and other infrastructure items. archaeological underwater explorations.
