Cooling Systems for a New Generation of Ferries.
Project: Q-West Electric-Hybrid Ferries for Auckland Transport
Location: Whanganui / Auckland
System: Aquatherm Blue PP-R
Application: Closed-loop cooling systems
Partner: Q-West Boat Builders
Building a new generation of electric-hybrid ferries meant solving new engineering challenges - including how to cool advanced propulsion and onboard systems reliably in a demanding marine environment.
USCO was involved well before the pipe was installed.
The Challenge
The cooling systems needed stable thermal performance, resistance to internal corrosion and confidence over a long operational life. With specialised equipment, marine conditions and multiple project partners involved, system approval could not be based on assumptions.

The Solution
USCO worked alongside the Q-West team through chemical testing, design input, product supply and fit-out support.
The Aquatherm Blue PP-R Piping System was approved for the ferries’ closed-loop cooling circuits. Its corrosion-free material and fused jointing system made it a strong fit for maintaining system integrity and efficiency over time.
The value of USCO’s involvement was not limited to supplying a suitable material. It was being available through the technical conversations, helping test the application and staying close to the build as the system moved from design into the vessels.

The Outcome
Aquatherm Blue successfully integrated into the ferries’ closed-loop cooling systems
A corrosion-free solution suited to harsh marine environments
Stable thermal performance supporting hybrid propulsion infrastructure
Reduced long-term maintenance risk compared to traditional materials
Technical support carried from early design through fit-out
On a project built around new technology, early collaboration helped give the team confidence in the system behind it.
