Testing

Assured performance for over 10 years

As a global leader in the design and manufacture  of subsea solutions and  systems, Matrix  Composites &  Engineering understands the need for rigorous testing and validation of products used in harsh, deep water environments.

Matrix’s quality and operational reliability is supported by our Subsea Test Facility located at the company’s head office in Western  Australia, home to the  largest composite syntactic manufacturing plant in the world.

Boasting the Southern Hemisphere’s largest commercially available hyperbaric chamber, the facility allows for the testing of a wide range of products from large energy exploration  support components, to items from the defence forces and small subsea electrical connectors.

Hyperbaric testing

Matrix’s hyperbaric test facilities are a key  Component of our  production process, and have been so for over 10 years. Operating within
Matrix’s ISO 9001 system and other international standards, such as those prescribed by the American Petroleum Institute, the facility uses state of the art control algorithms
and software logging tools to ensure precise control and high quality test data results.

Matrix’s 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

 

The facilities are supported by a 40-tonne crane that also services 300 m2 of working space with heavy vehicle access.

Consequently large structures can be easily carried directly to the workspace, unloaded, instrumented and loaded for testing in the same undercover area. The Matrix facility is licensed to carry out hyperbaric testing up to 5,200 metres sea water.

Chamber specifications

Matrix operates a suite of 11 hyperbaric chambers in a variety of sizes, with internal dimensions ranging from Ø0.1 X 0.2 m (max 45MPa) to Ø1.6 X 6.4m pressurised up to 52 MPa . The chambers are fully instrumented and capable of recording pressure, buoyancy loss and temperature changes over time.

The chambers have been designed with spare penetrations to facilitate functional testing of client-supplied equipment, such as cameras in chambers S2, S3, S4 and S5, during the pressure test. All chambers are orientated vertically to facilitate  loading and unloading  via our 40-tonne crane,  with larger chambers mounted underground
for safety and environment stability.

Laboratory and material testing

At Matrix, we invest heavily in research and development (R&D) to continually advance our  offerings and embrace new opportunities.  Many  of our products are registered under  international patents to  protect intellectual  property and demonstrate our culture of innovation.

Matrix’s head office  boasts a large R&D  facility run by scientists  and material engineers  from a broad spectrum  of high performing  industry disciplines. A range of on-site testing facilities allows raw materials or finished proeducts to be tested to relevant  internal, client and international standards before release.

  • Universal testing machines – for compression and tensile properties
  • Differential scanning calorimeters (DSC) – to determine reaction energies and glass transition temperatures of polymers
  • Thermo gravimetric analysis (TGA) – for determining decomposition temperatures and inorganic (fibre) content of composite plastics
  • Pycnometer – for determination of true density of solids (macrospheres)
  • Thermostatic water baths – for determination
    of long-term behaviours of polymer materials (creep, seawater resistance).
