Matrix Subsea Test Centre

Matrix Subsea Test Centre
ASSURED PERFORMANCE FOR OVER 10 YEARS
Our Subsea Test Centre, located at our head office in Western Australia, supports this commitment to quality and operational reliability. Home to the largest composite syntactic manufacturing plant in the world and Australia’s first Deepwater Hyperbaric Common User Facility, the Centre also features the Southern Hemisphere’s largest commercially available hyperbaric chamber.
This facility enables the testing of a wide range of products, from large energy exploration support components to defence force items and small subsea electrical connectors.
HYPERBARIC TESTING
Matrix’s hyperbaric test facilities are a crucial part of our production process over the last decade. Operating within Matrix’s ISO 9001 system and adhering to international standards such as those from the American Petroleum Institute, our facility employs state-of-the-art control algorithms and software logging tools for precise control and high-quality test data results.
Matrix standard tests include:
- Uplift determination
- Water ingress
- Instrumented buoyancy loss
- Hyperbaric compression and creep
- Hyperbaric collapse
- Bulk modulus
- Buckle arrestment performance
- Subsea controls testing
- Valve testing
- Variable temperature testing
HOME TO AUSTRALIA’S FIRST DEEPWATER HYPERBARIC COMMON USER FACILITY AND THE LARGEST CHAMBER IN THE SOUTHERN HEMISPHERE
The facilities are supported by a 40-tonne crane and 300 m² of working space with heavy vehicle access, we efficiently handle large structures for testing. Our facility is licensed to conduct hyperbaric testing up to 5,200 metres sea water.
HYPERBARIC CHAMBERS
Matrix operates a suite of 11 hyperbaric chambers in various sizes, with internal dimensions ranging from Ø0.1 x 0.2 m (450 bar) to Ø1.6 x 6.4 m (520 bar). These chambers, filled and pressurised with an eco-friendly fluid (water + glycol) to simulate subsea immersion, are fully instrumented to record pressure, buoyancy loss, and temperature changes over time. Environmental conditions are regulated from a single control room.

Designed with spare penetrations for functional testing of customer equipment, the chambers are vertically oriented for easy loading and unloading via a 40-tonne crane, with larger chambers mounted underground for safety and environmental stability.
THE MATRIX DEEPWATER HYPERBARIC COMMON USER FACILITY
Matrix has joined with the West Australian Government, SICA and Baker Hughes to pioneer Australia’s first Hyperbaric Common User Facility located within our Subsea Test Centre in Henderson, Western Australia.
The facility features Australia’s only integrated EUT frame and chamber system and clean room.
Benefits of the new facility include:
- Subsea equipment no longer needs to be sent overseas, decreasing carbon emissions associated with international transportation.
- 10-fold reduction in lead time.
- Access to the largest hyperbaric chamber in the Southern Hemisphere.
- A clean room facility to service sensitive equipment before and after testing.
- Appropriate for various subsea equipment including subsea control modules; pressure control and diverter modules; electric flying leads; UUVs; pressure housings.
