Underwater Tasks

At OQSG, we understand that certain underwater tasks just aren't the same as their topside counterparts, so we created our Underwater Tasks Course Library. These tasks are designed to meet or exceed the DOT requirements for Operator Qualification for Underwater Covered Tasks. We worked side-by-side with divers to create rich course content with animations, diagrams and real-world examples so your employees not only meet the requirements, but also retain the information they've reviewed, resulting in fewer mistakes and less accidents.
