High Voltage Cable Pulling Training Nears Release

As the global wind industry scales, so too does the demand for competent, specialised technicians. That’s why GWO is preparing to launch a new High Voltage Cable Pulling (HVCP) module as part of the High Voltage (HV) Standard, which is designed for technicians working with some of the most valuable items on a wind energy installation.

Developed with strong support from GWO members, this module is for technicians working in pre-assembly and installation phases of turbine construction, as well as teams working in service and operations.

Reducing the risk of downtime

Anyone familiar with HV cables in wind will know that these are big, heavy items often weighing 50+ kilograms per metre, and frequently much more. As such, this wind industry-specific training targets technicians who will join the HV Cable Pulling team as they inspect, protect and install the High Voltage (HV) and Medium Voltage (MV) cables within a turbine tower.

This vital work relies on technicians with training that helps them focus on the quality of cable-pulling activities, to reduce the risk of damage to cables and mitigate the impact of downtime and delays caused by a damaged power cable. Power cable failures are one of the main risks affecting wind farm operations: a failure can shut down an important part of an offshore wind farm, accounting for the majority of insurance claims in the offshore sector and for most of the unavailability of the wind farms.

An international collaboration

The draft standard was put to the test through two international pilot trainings in May 2025:

📍 Port of Blyth, UK – Delivered by The Wind Academy, training providers with HV cable works offshore field experience, this pilot contributed to the technical refinement of the standard.

📍 Vamdrup, Denmark – Co-delivered by Maersk Training and DELPRO Wind Academy, this pilot validated content against real-world industry demands.

These pilots mark an important step in ensuring the training is grounded in practice, not just theory, explained Thomas Redmond, GWO Training Project Manager:

This standard is a key example of how industry collaboration translates into practical, high-impact training. The pilots in the UK and Denmark have shown us how training providers can deliver cable pulling training to the highest standards of safety and relevance, supporting wind project timelines and technician capability alike.

Morten Dyhr Arildsen, Instructor at Maersk Training, added:

One of the key things we looked at was how to manage bending limits and cable stress, especially in tighter areas like towers or nacelles. Technicians need to understand why those details matter. It’s not just about getting the job done, it’s about making sure the people stay safe during the cable pull and that the system is reliable over time due to no damage to the cable.

Essential career training

The HVCP module is one of two within GWO’s upcoming High Voltage Standard and aligns directly with the Pre-Assembly and Installation pathways identified in the GWO Job Roles framework - offering a clear route for workforce upskilling.
