High-voltage work is inherently hazardous. Any team working with a range of marine high voltage systems must be on guard against incidents. A full understanding of safe procedures is essential.

MTCS’ corporate high voltage training courses serve as a standard for the ROV industry.

Course Overview

Over the 2-day course, your team will learn industry best practice. They’ll find out how to satisfy IMCA R005 and other legislation. Most important, they’ll develop a detailed understanding of HV safety.

On the first day, they’ll be immersed in the theoretical side of the course. The second day calls for a suitably equipped workshop. In this workshop, the candidate will sit a Practical Assessment. This requires them to carry out an Electrical Isolation. They’ll have to show they can follow your company procedures.

Candidate Requirements

Suitable course candidates will have some technical expertise and knowledge of ROV systems. Any level of skill above that can still benefit from this course.

Course Modules

  • Safety with High Voltage
  • System Components
  • Risk & Injury
  • Safe Systems of Work
  • Hazardous Areas


The theory test involves both Multiple Choice and short written answers. With a completed Practical Assessment, this forms the Assessment of Knowledge.


A Certificate confirming Successful Completion of Knowledge & Practical is awarded to those who pass the Assessment of Knowledge.

We can also provide a Certificate confirming a candidate is ‘Competent in ROV HV Systems’. For this, the candidate must also hold a valid Certificate of Competence at Senior ROV Pilot Technician (Submersible Engineer) or above. This qualifies them to act as ‘Isolating Authority’ at the employer’s discretion.

For a breakdown of Assessment Outcomes, please consult the flow chart.

Course Delivery

This course can be delivered at client premises globally. This allows us to focus on company equipment and procedures.

For clients whose teams operate in different locations, the most cost-effective solution is to train on board vessel. We recommend this happen in transit, or during crew change.


  • Practical assessments take place on day 2
  • Certificates of Competence can be issued by MTCS. Alternatively, they may be issued by an in-house Competence Scheme conforming to IMCA C007
  • All assessments are carried out by MTCS qualified assessors
