CASE STUDY:
Wind Turbine Hydraulic Pitch System
and Hose Upgrade
Overview
A new client reached out to us for support with hydraulic pitch
system and hose upgrades on their G8X platform turbines. They’d
been dealing with ongoing oil leaks and pitch system faults,
which had caused significant downtime across their site.
Coast Approach
We provided a team to carry out a full exchange of key turbine
components, including the pitch ram, link head (knuckle), pitch
ram supports (half moons), position sensor (Balluff ), hydraulic
contactor, and all associated hydraulic and gearbox hoses.
We also supplied our own site specific RAMS, work instructions,
and access work plan to support the safe delivery of the job.
As an extra we also fitted a new leak back kit to the turbine. This
acts as a backup in case of a future failure, giving added protection
and helping reduce the chance of unplanned downtime.
Deliverables
We upgraded the hydraulic pitch
system and replaced worn components,
resolving the faults and leaks that had
been causing repeated downtime. With
the new parts in place, the system ran
more smoothly and reliably. This helped
the client reduce downtime and avoid
the cost of new parts caused by pitch
faults or low-level sensor issues.
The turbines will operate
reliably and efficiently,
with less downtime and
enhanced protection
against future faults.
