Aquatic Engineering & Construction's modular reel drive systems can be up to 7m high when assembled.
Its offshore teams have to use harnesses and ladders to complete the assembly.
In addition to teaching best practice during normal operations, the course - developed by Survivex - will show Aquatic's workers how to secure and rescue a colleague who has fallen in the harness or become unconscious.
Aquatic commissioned the custom course to improve body positioning and establish good practice for personnel assembling the AQPR-02 modular drive system.
The course also covers the introduction of new work positioning harnesses that give technicians a higher degree of comfort and mobility while allowing them to use both hands for working.
The first training course was held in January and the content will be rolled out to all Aquatic offshore personnel during the first quarter.
Aquatic health, safety, environment and quality manager John Spellman said HSEQ was a vital part of the company's contract wins.
"We pay attention to the views and information contained in our internal observation card system, which encourages employees to report any HSEQ issues of concern," he said.
"This training course will empower and enable our personnel to familiarise themselves with the new equipment in a low-pressure environment before they use it on a project out on a vessel at sea.
"As a responsible employer working in a high-risk industry, we cannot afford to be complacent about the health and safety of our people."
