      Working with a small boat. Vibro Corer assembled by hand for 2-3 hours, work can be done with a relatively small vessel. Deep-sea work. Vibro Corer designed to operate at a maximum depth of 300 m. A modified version is designed to operate at a depth of over 600 meters.

      Electric Vibration Sampler SEABED

      Electric Vibration Sampler Company SEABED SVC-series has a great track record and has been successfully used by our company all over the world on different types of soils, including soils containing gravel.

      Electric companies SEABED Vibro Sampler was designed to produce a cylindrical core sampling in soft soils and viscous at a maximum depth of 50 meters (standard version).

      Once the device is placed on the seabed, electric Vibrogolovka drives the core barrel, lowering the liner into the seabed. Stationary piston system promotes the invasion of seabed sediment with minimal impact on sedimentary soil. After returning to the starting position and the sample catcher tube can be rotated to a horizontal position to facilitate removal of the liner with the sample. The indicator allows you to check the penetration achieved.



      Standard set for Vibration Sampler includes 3, 4 and 5-foot frame, as well as other sizes available at your convenience. Two tubes with a diameter Ø70 mm or Ø108 mm. When all the components are mounted on the support frame relative to the entire unit is easily transported via a 20-foot.

      CPTU is the most versatile tool currently available for field studies of soils. In addition to indentation resistance and abrasion friction cone sleeve (traditional CPT), measurement of the pore pressure (u) gives important information about the properties of the soil. The battery-powered probe with the transmitter mounted at the end of 36 mm and CPT rod is pressed into the ground at a speed of 2 cm / s. Passing through the various layers of the soil, the probe registers a change in their properties, typically once per second. The data are continuously transmitted to a computer operator at the surface.

      Wireless CPTU - universal tool for field studies of soils


      CPTU probe and a wireless transmitter with the battery in the battery compartment

      CPTU is a very useful tool for field studies of soils. In addition to the penetration resistance and the friction of the cone friction sleeve (traditional CPT), measurement of the pore pressure (u) gives important information about the properties of the soil. Built-in inclinometer will give you the opportunity to know the deviation from vertical direction of pressing, and will help you calculate the actual depth sensing. The continuous transmission of data gives information near real-time on the operator screen and an automatic alarm system, which can automatically stop the operation of the installation, for example, if there utykanie in stone. Wireless data transmission is possible, mainly by means of radio waves or acoustic signal.

      The wireless transmission of the acoustic data.


      Wireless data transmitter.

      Using a wireless transmission from the probe to the surface provides the operator with a significant near-real-time information, and at the same time, work with equipment greatly facilitated the lack of cables. Transmitted in real time, data from the inclinometer can be used to deliver alarms and automatic stops pressing, for example, if the probe is buried in the rock.

      There are two basic technologies for wireless data communication - via radio waves, and an acoustic signal. In both cases a combined transmitter and a battery compartment connected to the probe. The receiver is mounted on the rig with the encoder depth and usually connected to a laptop with recording software via the interface unit.

      Acoustic data transmission.

      The transmitter of sound is at the top of the transmitting device. It transmits audio signal through the steel rods to the receiving microphone which is in direct contact with them. The microphone is placed in a very strong shell, so that through him it was possible to produce indentation probe. Acoustic Transmitter can be used both on land and at sea.

      Data transmission via radio waves.

      Radio antenna mounted at the upper end of the transmitting device that emits in the microwave range through the hollow space of the drill rod. The receiver is located on the mast of a research setting. It is important that the receiver is located above and aligned with the rods in the hollow container was clean and dry.

      The system is intended for calibration of sensors on the cone resistance (Qc), side friction (fs) and pore pressure (u), located in the probe Geotech CPT NOVA

      Global Navigation Satellite Systems (GNSS)

      iconThe global satellite systems of positioning, operating in the differential C-Nav mode are intended for determination of coordinates with high accuracy, practically in every point of the Earth. GNSS receivers of the most authoritative world company Trimble are used in the Caspian Engineering Company. RTK of Trimble system provides centimeter accuracy in real time and can be used in the most various offshore and onshore works

      Acoustic and Seismoacoustic Profile Recorders

      iconThe Seismoacoustic source of "Bumer" type is designed for works with application of high power and has an additional benefit — change of frequency of a signal due to change of energy of a source of CSP-D. It allows to achieve increase of width of an impulse of a signal not available earlier. The increase of width of an impulse provides more big penetration with quality preservation of a single impulse.
