Anti-Fouling Paint and Inspecting Ship Hulls
Inspecting ship hulls to survey the integrity of Anti-Fouling paint can be easily conducted using an underwater drone; Deep Trekker pilots do it every day.
Anti-fouling paint is used to coat the underside of ship hulls to temporarily hinder the growth of subaquatic organisms; otherwise known as biofouling. This collection of organisms would otherwise build up on the underbelly of the ship which would greatly reduce the vessel's overall performance and impact its ability to operate. A series of distinctive coatings are applied to the outside of the ships hull to counter the growth; supplementary to the paint's anti-fouling properties, additional layers are often applied to act as a barrier against hull corrosion; acting as sacrificial anodes. This protective coating does not last forever and requires constant monitoring to ensure the integrity of the hull is maintained also safeguarding the surrounding ecosystem from any harmful materials.

Deep Trekker's underwater drones, known as Remotely Operated Vehicles (ROVs) are the ideal solution to ship hull inspections. With onboard lithium-ion rechargeable batteries, the ROV systems require no topside power or generators to operate; allowing them to be deployed within seconds from anywhere on or around the vessel.
Being that most inspections will be done at sea, both the DTG2 and DTX2 underwater drones sport a robust aluminum die-cast body to handle the harsh ocean environment. Among the many standard features of the ROVs, is the built-in high-definition camera which records and live streams video to the operator on the surface. The camera can rotate to see what is above and below the unit - offering a 330-degree field of view around the ROV. Operators are able to pilot the underwater drone to areas of interest and capture them all from the hand-held controller.
Further inspection of the vessel can be done with the industry-leading Cygnus thickness gauge attachment. This add-on feature to the ROVs enables inspectors to easily determine the metal thickness of the ship's hull or the level of corrosion without clearing away any protective coatings.
