Marine & Subsea

PSG in the sea.

Saltwater, cold, pressure and sunlight: we supply materials that resist all four while keeping the compressive strength and mechanical properties your design depends on.

Submarine

Why choose us

Engineered for the harshest environment there is.

Fully submerged components face saltwater, cold and high pressure. We supply materials that resist degradation while keeping the compressive strength and mechanical properties the application requires.

Partially submerged components must also withstand sunlight, which weakens materials over time. And as parts move between cold seawater and hot sun, designers have to allow for thermal expansion and contraction.

How we help our clients

Getting it right first time, below the surface.

  • Decades of marine experience

    Choosing the right material is difficult. Our technicians share decades of marine and subsea knowledge with your engineers.

  • Reliability where it counts

    Subsea, unplanned maintenance is complex and hazardous, so reliability is critical from the start.

  • Proven with major operators

    We have worked with major oil and gas and naval organisations.
