  • Submersible electrical and electronic system repair
  • Independent maintenance support during forward deployments

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

ROV Pilot Technician

ASDS mechanical, electrical and electronic maintenance provides a technical background relevant to Oceaneering's entry route for ROV pilot technicians.

How to prepare: Apply through a technical-entry route using documented ASDS maintenance experience, and seek employer-specific training in ROV handling, manipulators and tooling before offshore deployment.

What the civilian work involves
  • The pilot flies the ROV, and operates the manipulator and/or specialized tooling to complete the assigned task.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Preventive and corrective maintenance of ASDS electrical and electronic systems transfers to industrial equipment troubleshooting and repair.

How to prepare: Complete practical training in industrial electronic fault diagnosis using test equipment to bridge from submersible systems to commercial equipment.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Set up and test industrial equipment to ensure that it functions properly.
  • Inspect components of industrial equipment for accurate assembly and installation or for defects, such as loose connections or frayed wires.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Notes & Sources

  • The ROV technical-entry and training route reflects Oceaneering's representative pathway, not a current vacancy or universal industry entry standard.
