The MTCS online High Pressure Hydraulics training course is designed to provide ROV technicians and engineers with a fundamental knowledge of ROV hydraulic systems.

The course is suitable for a range of disciplines and particularly in cross training personnel with electrical and electronic disciplines who need to multi skill.

Course Overview

The course covers both general hydraulic theory, high pressure hydraulic safety and can be applied to many ROV hydraulic systems. It provides an industry specific primer for personnel who are familiar with more general hydraulic principles.

The course is also suitable for personnel who are involved with the operation and maintenance of ROV Launch and Recovery (LARS) systems including Tether Management Systems (TMS).

The course is delivered in 2 stages. Stage 1 is delivered as an e-learning module and covers theoretical concepts, whereas stage 2 consists of a booklet that requires candidates to research their own systems, procedures and work methods.

Candidate Requirements

The course is ideal for ROV technicians and engineers who have little or no experience in hydraulic systems, and are required to enhance such as part of their career progression.

The course also assists in multi-skilling technicians and engineers who are more electrically biased.

Course Modules

The course includes the following modules:

Stage 1

  • Hydraulic Theory
  • Hydraulic Components
  • Safety of Personnel
  • System Components and symbols
  • Contamination Control

Stage 2

  • Hydraulic Fluids
  • Hydraulic Pumps
  • Actuators
  • Pressure Control Valves
  • Directional Valves
  • Flow Control and Non-return Valves
  • Servo Valves
  • Reservoirs, Compensators and Accumulators
  • Conductors and Seals
  • Contamination Control
  • Hydraulic Filters
  • Fault Finding and Maintenance
  • Symbols


Assessment of Knowledge is conducted by a combination of Multiple Choice and short written answers.

Each module includes a range of short written assignments that requires the candidate to reflect on their own systems, work methods and procedures. This forms an important part of the candidates learning experience and ensures the training remains contextual.

Each module also includes an end of unit ‘Self-Assessment’ that provides the candidate with an opportunity to test themselves on the specific subject matter. All ‘Self-Assessment’ modules must be successfully completed before taking the final Online Assessment of Knowledge.

On successfully completing the final assessment of knowledge candidates will receive a certificate confirming ‘Successful Assessment of Knowledge’.

The Online course includes a Practical Assessment that can be completed offshore or in a suitably equipped workshop. The Practical Assessment requires the candidate to conduct an Electrical Isolation, under Supervision, in accordance with their company procedures. Supervision may be provided by an occupationally competent ‘Technical Authority’ which in practice may be the Offshore Supervisor.

On completion of the Practical Assessment candidates may upload specific evidence of the activity to their MTCS Online account for final verification by MTCS.


Successful candidates will be awarded a Certificate confirming Successful Completion of Knowledge on completion of the Online course. On completion of the Practical Assessment candidates will then receive aa certificate confirming successful completion of Knowledge and Practical.

Candidates who hold a valid Certificate of Competence at Senior ROV Pilot Technician (Submersible Engineer) or above may be awarded a Certificate stating that they are ‘Competent in ROV HV Systems’. This certificate qualifies the candidate to act in the capacity of ‘Isolating Authority’ at the employer’s discretion.

A detailed overview of the Assessment Outcomes can be seen in the flow chart.

Course Delivery

The course is delivered through MTCS Online whereby candidates will be provided with a unique access code to download the material and guidance on how to use the course.


Certificates of Competence may be issued by MTCS or by a Company in house Competence Scheme that conforms to IMCA guidelines C007.
