Submersible THETIS
BIGunderwaterThe manned submersible THETIS was constructed, in 1999 in France by the company COMEX S.A, to very high technical specifications and has great potential for a wide range of scientific activities.

It has a wide optical field, with distinct advantages over previous submersibles using older technologies. It is fitted with light projectors of advanced technology specially equipped for photography and cinematography. In addition it has a special intercom system for communication with the research vessel AEGAEO of which it forms an integral part.


OLYMPUS DIGITAL CAMERAShe has a modern sonar echo sounder of high resolution which provides high standards of safety in terms of visibility, and it is particularly effective for the location of wrecks., communication systems (UHF, VHF, underwater telephone), a special com system with the R/V AEGAEO, navigation systems, cameras and powerful lights for photography and cinematography.

She is equipped with 2 robotic arms (5 and 3 axis of movement) for its many applications and range of activities, with the possibility of lifting objects of up to 100 kg in weight.. For the atmosphere control she is equipped with the appropriate gas meter instruments. She is also equipped with cutting equipment, hydraulic pistons, vacuum pumps, etc., for special needs.

ROV Seabotix Supporting research in shallow water (about 300 m)
ROV Seabotix Equipment General Operation The HCMR small ROV system is small lightweight observation class ROV (Seabotix LBV200L2). The total system (ROV, power/control system and cable) weighs less than 100 kg and is transported in 3 waterproof cases. The ROV has a depth rating of 200 m, with two video cameras, LED lights, scanning sonar and a single-function manipulator. The system requires a 1 kW power supply at 220 VAC. The umbilical consists of 250 m of thin cable (with power conductors and fibre optic video) on a drum with slip-rings. The ROV vehicle weights less than 15 kg and can easily be deployed by one person with another acting as pilot. It is an ideal vehicle for shallow water observation working from small boats.
The SeaBotix LBV200L2 takes the highly capable and successful LBV1502 to the next level with a longer 250 meter (810ft) umbilical, an increased depth rating to 200m, more powerful Brushless DC Thrusters, 480 lumen internal LED Lighting, fiber optic video and FSK electronics.
Powerful Thrusters The LBV200L2 is equipped with four powerful, oil-compensated, Brushless DC Thrusters. There is 1-lateral, 2-forward, and 1-vertical thruster, enabling maneuverability in four axes, just like a helicopter. The additional lateral thruster adds the capability to fly sideways, allowing the operator to keep either camera on target while piloting along a ship hull or dam surface. On-the-fly, 10-step variable power control to each axis allows for smooth video and sensor recording. For added reliability, serviceability, and peace of mind, each thruster is identical and independent of the vehicle enclosure, ensuring no dynamic seals penetrate the vehicle?s electronics enclosure.
Long Umbilical The LBV200L2 can operate at its full 200 meter (660ft) depth with a generous 250 meters (820ft) of our revolutionary small diameter umbilical. Managing the long umbilical is simple with the heavy duty reel. Use of fiber optics in the umbilical is transparent to the operator by using a special transmitter potted into the umbilical, with only a wet-mating connector needed externally. The extremely small-diameter of our umbilical presents at least 25% less drag than other systems meaning the vehicle is controlled by the operator, not the umbilical.
Intuitive Controls Operation of the LBV200L2 is simple with the standard Integrated Control Console featuring the acclaimed LBV Hand Controller. Standard Auto-Heading, Depth, and Trim, as well as all system functions are at your fingertips in a logical, simple layout. Added features include the 38 cm (15") monitor behind a waterproof panel, sunshade for direct light operations and sealed components for harsh environment operations. The programmable Video Overlay displays heading, depth, temperature, thruster gain settings, auto settings, cable turns, and time/date.
High-Quality Video and Sensor Data The Fiber Optic video system provides crystal-clear images from the standard high-resolution color and low-light B/W cameras. Both cameras have a total 270? field of view through 180? rotation of the camera enclosure. The internal, fully-adjustable LED Lighting array provides brilliant, white light as it tracks the color camera. Custom FSK electronics are included to provide an additional RS232 channel for options such as sonar for harsh environment operations.
The programmable Video Overlay displays heading, depth, temperature, thruster gain settings, auto settings, cable turns, and time/date.
Grabber & Attachments The LBV200L2 can be fitted with the three jaw grabber enabling retrieval of both large and small objects. With exceptional gripping force the grabber can clamp onto heavy objects and then retrieved by pulling in the umbilical. Open and close functions are done by the LBV hand controller. The standard three jaw assembly offers attachment to objects in various positions.
In addition to the three jaw attachment the grabber can be fitted with a Parallel Two Jaw attachment, Interlocking Three Jaw attachment or Cutting Blade. Each of the attachments are simple to install and also available as an entire kit including case, tools and spare blades.
External Lighting For use in conditions that require maximum light the LBV200L2 can be fitted with external lighting. The external lights offer greater coverage in a fixed direction. Use of the internal lamp can be done at the same time and is needed in the up or down camera position. Intensity and on/off is controlled by the LBV hand controller.
Scanning Sonar The LBV200L2 can be supplied with the latest Tritech Micron DST scanning sonar. Unique to the LBV is the ability to transmit the data through the onboard electronics eliminating the need for a larger diameter umbilical. The Micron is an exceptional sonar with high resolution images up to 80 meters (262ft) and a full 360 degree scan. Use the sonar to help locate objects at distance or in turbid water.
