Submersible magnetic robot performs hull inspections

A new underwater inspection vehicle was introduced to the North American market at the 2017 International WorkBoat Show in New Orleans, Louisiana: The three wheeled Deep Trekker DT640 Utility Crawler.

DT640 Utility Crawler houses its own on-board batteries, making deployment quick and easy

Equipped with an HD camera, magnetic wheels, and a multitude of application specific add-ons, the Crawler is capable of performing a wide array of tasks for the workboat industry. The magnetic hull inspection vehicle is said to be versatile and easy to deploy at a moment’s notice.

Deep Trekker President and CEO Sam Macdonald spoke about demonstrating the company’s latest products, including remotely operated vehicles or underwater drones, at this year’s International WorkBoat Show. “The new DT640 Utility Crawler product line has been developed by listening to the needs of the industry and our customers, and we are thrilled to be showcasing it in New Orleans. Deep Trekker continues to innovate to provide the easiest to use and most portable inspection technologies, without compromising durability or capabilities.”

Submersible to 50 metres, the DT640 Utility Crawler houses its own on-board batteries, making deployment quick and easy for tasks such as contraband inspections and testing hull integrity. Magnetic wheels and various add-ons permit diverse applications such as scraping away marine growth, testing hull thickness, or examining for invasive species while in port. The Utility Crawler has both military and municipal applications as well.

HULL INSPECTION
With magnetic wheels, the DT640 Utility MagCrawler can crawl along vertical and horizontal angles to inspect the integrity of a ship’s hull, even underwater. Instead of dry docking or returning the ship to port, crew members can immediately inspect the hull via live video on the handheld controller or do inspections with an integrated sonar to look for problems or concerns.

HULL SECURITY CHECK
When entering ports, authorities or crew can efficiently check areas of interest for contraband, invasive species, or security threats.

REMOTE PRESSURE WASHING
Outfit the device with a pressure washer in order to remove dirt, debris, rust scale and more for spot inspections, all of which can be piloted with the handheld controller.

REMOVING MARINE GROWTH
The dozer attachment is designed to remove hard marine growth by scraping surfaces with 50lbs of force.

The DT640 Utility Magnetic Crawler can also determine the thickness of metal on corroded and coated structures by mounting a thickness gauge probe on its arm. The magnets give the Utility Crawler the ability to travel in almost any direction on ferrous metal surfaces.
