We sell, customize, and repair ROVs like the BlueROV2. We also supply subsea parts from Blue Robotics, Cobalt, Cerulean, and WaterLinked.
The Great Lakes Shipwreck Historical Society announced last week the discovery of a WWII-era ship that sank in the world’s largest freshwater lake, Lake Superior, between Canada and the USA. The vessel is the 244ft bulk carrier SS Arlington, that left Port Arthur, Ontario, on 30 April 1940, and was sunk early on 1 May after …
ROVs are fantastic tools for underwater activities, like visual inspections of assets, habitat mapping, search and rescue, etc. Just one recent example is an ROV being used to visualize dredging activity for deep-sea quay construction in the Port of Rotterdam, Netherlands.

Blue Robotics just announced their 5″, 6″, and 8″ locking enclosures into their watertight housing family. These enclosures are rated to 500m to 1000m depths and end-cap options are flat, aluminium, with and without pre-drilled M10 holes. The online configurator has expanded to included these new sizes and we can also order any of these parts …
Cerulean recently launched the Insight-240, a forward-looking, multibeam sonar that images an entire 90-degree sector on every ping. This video-like capability is ideal for all condition navigation, target location, tracking and general situational awareness.
You can observe echoes from objects like ropes, walls, dock pilings, shipwrecks, boats, fish, and any other structures or objects that reflect sound waves. The generated image provides a compelling reference for navigation regardless of water visibility, allowing for the localization of essential features quickly.
The Insight-240 is a 240 kHz, 150m range, 300m depth rated system. For general purpose applications, a mounting bracket incorporating a servo tilt mechanism is highly recommended.
The Water Linked Doppler Velocity Log (DVL) is the smallest in the market, operated by estimating velocity relative to the sea bottom by sending acoustic waves from the four angled transducers, then measuring the frequency shift (doppler effect) from the received echo. By combining the measurements of all four transducers and the time between each acoustic pulse, it is possible to very accurately estimate the speed and direction of movement of an ROV.
Utilizing a Water Linked DVL, an ROV operator will feel a whole new level of stability and control of the ROV so work can be carried out with full confidence. The quality of the video will increase dramatically using the DVL, as the ROV will be significantly more stable.
- Maintaining stability while operating ROV tools or performing detail inspections
- Station keeping in challenging situations like ocean currents or tether pull
- Terrain following
- General velocity feedback for vehicle control
Blue Robotics released the Ping360 in September 2019, a mechanical, single-beam, scanning sonar for navigation and imaging. It has a 50 meter range, 300 meter depth rating, and an open-source software interface that makes it a very capable tool for ROV navigation and underwater acoustic imaging.
