Ocean Module's revolutionary V8 Sii (Search, Identification and Intervention) Mini Observation ROV is the latest edition to the AUS-ROV remotely-operated vehicle arsenal. With an eight T110 vectored thruster arrangement and extremely advanced control ... Moresystem, the V8 Sii ROV allows its Pilot to fly with 360° freedom of movement in six dimensions. Any desired angle and position can be held indefinitely, at any depth, as required.

The Pilot Control Unit (PCU) provides all the controls an ROV Pilot needs to handle the V8 Sii ROV in one simple handheld unit. These include speed, direction, depth, pitch, roll, trim, light intensity, camera pan and tilt, and autopilot.

The Surface Unit (SU) provides the power required to operate the V8 Sii ROV. For added safety it includes constant insulation monitoring with a warning LED as well as automatic cut-out. It also has an interface for all the inputs and outputs, such as telemetry, video, sonar, Ethernet, USB and RS-232.

Ocean Modules provides a variety of cables for use with the V8 Sii ROV. The standard cable is a 12mm neutral buoyancy cable housing power conductors and three twisted pairs for control, video, sonar and other sensors. It is available for lengths of up to 500m and can withstand strain of up to 500kg. A fibre optic option is also available for HD video, longer tethers and higher bandwidth requirements.
Robertson Geo's PS Logger Probe is a low-frequency acoustic sonde designed to measure compressional (P) and shear-wave (S) velocities in soils and soft rock formations. It operates using indirect excitation rather than mode conversion as in a conventional ... Moresonic. It is capable of acquiring high resolution P and S wave data in borehole depths of up to 600m in water.

The PS Logger probe contains a unique design of powerful hammer source and two receivers, separated by acoustic damping tubes. To acquire data, the probe is stopped at the required depth and the source is fired under surface command. Firing causes a solenoid-operated shuttle aligned across the borehole axis to strike plates on opposite sides of the probe in turn, setting up a pressure doublet in the surrounding fluid. The resultant fluid motion produces a tube wave at the borehole wall with velocity close to the shear velocity of the formation together with a compressional wave.

As the waves propagate parallel to the borehole axis, they set up corresponding fluid movements that are detected by the two neutral buoyancy 3D hydrophone receivers and geophones, allowing the wave velocity to be determined. The facility to stack multiple shots and filter the data as in normal seismic data acquisition is included in the operating software.
The WISON-APB-Classic is capable of performing cone penetration tests (CPTs) and taking soil samples at depths up to 550 m (water depth + drilling depth). It requires a drill string with an inner diameter of at least 101.6 mm (4") and a drill tower clearance ... Moreof 11 m. The WISON-APB 100 version has a pushing capacity of 100kN and is capable to performing tests with a 1m and 3m stroke length. The WISON-APB 100 comes with an electric winch that is self-tensioning for heave compensation. The winch allows the tool to travel at a maximum speed of 2 m/s inside the drill string.

The Flat Dilatometer (DMT) is an in situ test for the determination of various key soil parameters used for geotechnical design. The test is rapid, accurate, simple and cost-effective. The results are highly repeatable and independent from the operator. ... MoreThe blade may be advanced with most common field machines, including penetrometers and drill rigs. DMT measurements are performed in situ, directly on the soil in its original position and state. This eliminates the disturbance caused by drilling, sampling and transport to laboratory. The profiles of the results are available real time during test execution. The direct measurement of soil deformation enables accurate estimations of the elastic modulus. The KD parameter provides stress history information of the soil, a very difficult property to estimate with other testing methods.

The Geoforce DTS® deep-tow boomer/sparker system is a high resolution sub-bottom profiler incorporating the boomer and sparker subsystems in a single tow fish. The system has been designed for use in the world’s toughest offshore environments, where ... Morereliability, ease of operation, accuracy and optimal data resolution are of paramount importance.

Geoforce Group have implemented fully digital communications between the towed equipment and topside equipment, allowing in lossless hydrophone and sensor data. The Geoforce DTS® is the only system to have two acoustic sources integrated in the same tow body, the selection of the acoustic source can be controlled by the surface interface - Geoforce Cerebella.

The evolution of the Geoforce DTS® Boomer/Sparker Sub-Bottom Profiler over more than four decades is an important case study in successful Canadian Government/Private Sector collaboration (McKeown et al, 2014). It demonstrates how a survey tool can retain its competitiveness in global seafloor mapping through continuous improvements building on the solid Huntec DTS core technology.
