Plastic for lightweight and corrosion resistant Subsea Equipment

Subsea environments lead to a number of significant demands placed on equipment, whether it is shallow or deep water environments. Two key issues to consider with all subsea equipment are weight and resistance to corrosive sea water. Our thermoplastics and composites offer significant weight savings over conventional materials like steel and aluminium: Our Polystone® grades (PE/PP) are naturally buoyant while engineering & high temperature grades plastics such as PEEK, PEI, POM, PK, nylon and PET are approximately 50% the weight of aluminium. Durostone® composites offering increased mechanical properties whilst only weighing approx. 25% the weight of steel. This coupled with polymers natural corrosion resistance, offers the potential for future subsea components to be smaller, lighter and free of cathodic protection – leading to efficiency and economic advantages in future equipment designs.

Your advantages

  • Naturally corrosion resistant materials
  • Weight reduction (reduced need for costly buoyancy)
  • Long-lasting and low maintenance: resistant to corrosive salt water and hydrocarbons
  • Economic advantages: Possibility for cathodic protection free equipment

Typical areas of application

  • ROV components and equipment.
  • Pipeline-Systems
  • Connectors (electronic and communication).
  • Support structures (e.g. pipeline repair equipment, tee sleds, subsea tree frames).
  • Subsea tree & wellhead components (protection/insulation)
  • Signage
