Robotic Tooling

Utility Vacuum Crawler for cleaning sediment and sludge from the bottoms of water storage tanks.

The VAC is a three wheeled crawler with rubber wheels to help with traction in concrete, steel, lined, glass fused to steel and other tank types. The vacuum head is mounted in front of the vehicle on a dual actuating arm, one actuator tilts the head 20 degrees and the other raises and lowers the head 20 degrees. The head concentrates the suction at the floor of the tank to focus the pumping of water on sediment filled water. The head has two intakes, 2″ in diameter (50mm), where you connect a flexible hose. The hose connects to a pump outside of the tank. There is a camera on the main body of the crawler that monitors the vacuum head as it removes debris.

Non-destructive testing tool, the ultrasonic thickness gauge probe.

Cygnus’s industry-leading ultrasonic thickness gauge can be integrated onto your magnetic crawler, allowing you to evaluate the thickness of steel on tanks, hulls or other metal surfaces without needing dive intervention or draining the asset. This ultrasonic thickness (UT) probe presses on the surface, taking an accurate measurement even through marine growth or coatings. The data is then displayed and recorded via Cygnus software on a laptop. The probe is able to take readings through up to 1/2″ or 12mm of soft marine growth or coatings to take a reading of the steel. This is a great tool for corrosion surveys for UWILDs on FPSOs or Vessels, as well as for steel tanks and pipes and other surfaces.

Caviblaster/Pressure Washer for underwater cleaning.

This is a safer and more cost effective alternative to using divers to clean a structure or bringing the structure or vessel out of the water for cleaning. The Caviblaster is mounted on an actuator on our robotics, which is able to rotate 90 degrees, allowing you to get the optimal angle on the surface that you are cleaning. The caviblaster uses vaporization, bubble generation and bubble implosion, which generates shockwaves that release tremendous amounts of energy to allow for easy separation from the surfaces being cleaned.

Plow kit for pushing material in front of the crawler.

The dozer kit connects to the DT640 arch, which enables it to be rotated 20 degrees as well as raised and lowered 20-degrees to get the optimal angle on your target.

Multibeam Imaging Sonars for ROVs

At Ven-Tech Subsea, we pride ourselves on delivering top-tier subsea inspection and exploration solutions. Our advanced ROV systems are equipped with state-of-the-art Multibeam Imaging Sonar technology from Blueprint Subsea, ensuring unparalleled underwater imaging and data collection capabilities.
Why Choose Multibeam Imaging Sonar? Multibeam Imaging Sonar offers a comprehensive and detailed view of underwater environments, providing high-resolution images and accurate measurements. This technology is essential for a variety of applications including: Marine Research Underwater Construction Pipeline Inspections Wreck and Obstacle Detection Environmental Monitoring.

Blueprint Oculus Multibeam Sonar | M3000D

The M3000D is the best sonar option for short range inspections. Utilizing the highest frequency in its class, the M3000D is perfect for identifying targets and close range navigation, as well as detailed inspections with the highest resolution of any 2D imaging sonar. Integrating directly into the ROV and viewed on the handheld controller, the M3000D provides users with a solution for close range inspections in murky water. Providing a reliable set of eyes regardless of turbidity, the M3000D allows operators to identify targets in search and recovery, provide insight in UWILD hull inspections and assist in navigation.

Blueprint Oculus Multibeam Sonars | M1200D

The M1200d multibeam imaging sonar conveniently mounts to our ROVs or Utility Crawlers for effective target identification in turbid waters. The M1200’s high operational resolution features a peak frequency of 2.1MHz, an integrated velocimeter for improved accuracy, and a range resolution of 2.5mm for detailed close-range inspections. The M1200D short-range imaging provides the highest quality image in the M-series sonars. Ideal for up close inspections of submerged structures and diver monitoring in turbid waters. In murky water, you might need to move your ROV within just a few inches of the hull to get an effective visual. The problem with this is that it then becomes very difficult to understand your position under the vessel, especially large cargo vessels or cruise ships, and it also takes significantly longer to perform the inspection. Using an imaging sonar, you can visualize the hull from further way, and identify anomalies through that murky water while also seeing more of the ship to give you positional awareness.

Oculus C550d Multibeam Imaging Sonar

The C550d Multibeam Sonar opens up a realm of possibilities for Ven-Tech Subsea’s search and recovery teams, inspection, marine research. The C550d defies limitations, delivering impressive imaging capabilities that allow Van-Tech Subsea to identify solid structures and targets even in low visibility scenarios. This sonar allows us to navigate confidently and make informed decisions based on the crisp, high-quality sonar footage. Beyond navigation, the C550d empowers us with the ability to conduct thorough inspections. Whether we are verifying targets, assessing underwater assets, or ensuring safety, this sonar offers the clarity and detail we and the client need to excel.

Low-Visibility Operations

Cameras and divers’ eyes often are unable to effectively search due to poor visibility underwater. An imaging sonar is the best tool to then reidentify the target since oftentimes side scan data does not produce an exact location (so navigating back to the potential target can be difficult. Once the target is reidentified, the sonar can be used to continue to track the target as you move closer, and when you get close enough, it can even be used to perform the visual verification.
Our Oculus M-series multibeam sonars are a new generation of imaging sonar, designed for use across a wide variety of underwater applications.
Their small form factor makes them ideally suited for deployment onto micro sized ROV platforms, while their rugged construction also makes them an excellent choice for larger work-class vehicles and subsea infrastructure.
