Glassfiber Reinforced Epoxy (GRE) Pipe Systems

You Should Know

Meeting Classification Societies’ rules and IMO regulations, GRE systems are designed specifically for use onboard ships.

In supporting the successful deliveries of marine scrubbers installations on vessels (to comply with IMO’s 1st Jan 0.5% SOx cap), BOS has transformed to become the material stockist of GRE (Glass Reinforced Epoxy) pipes, which are essential for SOX (Sulphur Oxide) scrubbers and  BWMS  (Ballast  Water  Management  System)  installations  for  vessel  retrofitting  projects.  BOS also specializes in turn key solutions in GRE pipes supplies, pre-fabrications, engineering designs, installations and commissioning.

  • Green specifications- 25% of the weight of  traditional  mild steel pipes, immune to corrosion
  • Reduction in weight of vessels equates to reduced fuel consumption
  • Free from maintenance and replacement requirements

to your needs.

When standard fittings (either R=1D or R=1.5D) are unsuitable,
tailor-made fittings can be designed and manufactured to
meet the specific requirement.


Prefabrication of fittings means that the number of system
joints can be minimised which will, in turn, reduce costs significantly.

GRE cost comparison to steel

Although the GRE material cost is higher than steel material, the
total installed cost of GRE is similar to steel piping. Moreover,
mounting GRE will contribute to lower through life cost.
In comparison with galvanised and rubber lined steel and CuNiFe, the installation costs of GRE systems are lower as a result of GRE’s lightweight nature and ease of handling. Installation and prefabrication training can be provided by FPI either at our facilities or at the customer’s site.

Naval Marine Applications

Rigorously and successfully tested for use onboard naval vessels, both Wavistrong & Fibermar are suited to many applications onboard both future and current generations of warships and submarines in service throughout the world.

Tangible benefits to both the naval shipyard and the Navy; Fibermar & Wavistrong are typically 60% lighter than CiNiFe, are highly resistant to erosion & bio-fouling, have a service life in excess of 25 years, are more cost effective to procure than CuNiFe, require no maintenance and installation cost and time are also dramatically reduced.

GRE Pipe


By spooling the pipes and fittings, installation time onboard can be significantly reduced with the bonus that installation costs are also reduced. Typically 70% of the spools for a job are prefabricated in controlled conditions either in FPI facilities, in shipyards or at the workshops of our preferred contractors.

Spools will be tested before leaving our workshops to ensure the quality of our product. Additionally, prefabrication reduces the number of bonded joints, and hence reducing the use of chemicals onboard.
