Underwater Drones and Monitoring your Hull's Paint Job
Last April we posted a blog that explored the prime reasons ship owners and operators should inspect their hulls on a regular basis. From paint jobs to contraband inspections, monitoring the status of a vessel’s hull is important to ensure the integrity of the structure and to reduce damage and the costs of wear and tear over time.

Today we are going to examine why paint inspections of hulls are so important. Maritime paint applications are unique in that the paint needs to be specifically designed to withstand a breadth of water temperatures, currents, ocean environments and bio-fouling organisms.

Monitoring the status of paint jobs can be a cumbersome and costly task. Traditional methods of performing hull inspections include hiring a dive team or dry docking (pulling the entire vessel out of the water). Both of these methods are quite expensive and this factor may lead to fewer inspections being performed. This is alarming because more than the capabilities of the ship's performance can be negatively impacted. The ship's hull can easily become a conduit for invasive species to migrate to new waters.

A Deep Trekker underwater drone, such as the DTG2 ROV or DTX2 ROV (for larger vessels), will allow ship owners and operators to monitor and assess the status of their hulls on a daily basis to combat against the buildup of organisms on the hull and will reduce their operational costs. In situations where anti-fouling paint is not used (which may become the case for all ships in the near future due to environmental regulations) the importance of regular inspections only increases.
Once biofouling organisms have built up on the hull, removing the species and cleaning the bottom of the ship can be a costly endeavor. The vessel may need to be dry-docked or may require sub-surface cleaning by divers to remove the critters living on the hull.
While in-water cleaning might seem like a viable solution, there are major ecological debates regarding whether it should even be allowed. Not only does hiring a dive team add cost, there is a widespread concern regarding the materials used to clean the hull and the toxins released into the water.

By inspecting the hull daily, operators can ensure that the paint job will be refreshed or restored as soon as signs of corrosion begin to appear. Daily or frequent inspections radically reduce the opportunities for organisms to build up and pose threats to new ocean ecosystems and hull integrity.
Deep Trekker ROVs are built to last. They are robust systems that are entirely portable and can be deployed within minutes. The ease-of-use they offer means that virtually any crew member can operate the underwater drone.
