Bondstrand Pressure Vessels

Fiber Glass Systems design and manufacture custom Bondstrand™ offshore composite (FRP/GRP) pressure vessels in accordance with a number of internationally recognised pressure vessel standards, in a range of sizes and pressure ratings.

Our composite pressure vessels are designed in-house and are manufactured using a combination of high quality resin infused components, and Bondstrand filament wound epoxy piping.

Typical composite pressure vessel Applications:

  • Ultra (UF) and fine filtration (FF) processes
  • Reverse osmosis (RO/SWRO)
  • General seawater filtration – including potable water applications

Example Vessel Design Codes:

  • ASME X (Class I and II)
  • BS4994
  • BS EN 13923


  • Corrosion resistant materials
  • Lightweight compared to metallic vessels
  • Designed for use offshore
  • Cost effective solution for end users
  • Configured to suit project specific requirements

Client feedback following project completion;

“The scope of supply on the BP Clair Ridge project included the design and manufacture of 290 GRE Sea Water Reverse Osmosis (SWRO) pressure vessels, which were an essential part of the BP LoSal™ package.

During the contact Fiber Glass Systems engineers and project managers worked closely with BP personnel to design, test, qualify, manufacture and successfully deliver the 290 SWRO vessels in a tight timeframe.”
