From 700kg down to just 76kg.
When people think of advanced composites, they usually picture racing yachts or aerospace. But composites also solve massive practical engineering headaches on commercial vessels.
Case in point: an 85-metre luxury passenger vessel operating on the Mekong River through Vietnam and Cambodia.
To pass beneath low bridges, its 700kg steel mast had to be lowered repeatedly. The sheer weight generated loads that damaged the wheelhouse roof, required crew members to physically help lift it, and relied on a hydraulic system prone to oil leaks.
Triac’s solution? A vacuum-infused E-glass and PVC foam core composite mast weighing just 76kg—an 89% weight reduction.
The result transformed the entire system:
* Replaced heavy hydraulics with a compact, remote-controlled electric actuator
* Completely eliminated structural loading on the wheelhouse roof
* Improved crew safety—no more manual lifting required during bridge transits
* Zero oil leaks and zero corrosion in demanding river environments
Could composites be the answer to your particular issue?
