Pultrusions in the marine sector

The GFRP thru-rod system we co-developed is a patented and award-winning technology

Marinas, oil rigs, and other underwater structures and equipment need to perform in a tough environment. Varying temperatures, sea salt, pollution, and wave action provide the perfect setting for material failure, particularly in steel and timber. This leads to a shortened design life, the need for costly maintenance programs, and harm to the environment.

Revolutionizing marina design

We worked with a world-leading marina designer to develop a GFRP solution to extend design life-cycle, eradicate the risk of corrosion, and advance the technology of marina components. Through extensive research and development, our GFPR composite solution has given our customers in the industry a competitive product that is in high demand worldwide. The GFRP thru-rod system we co-developed is a patented and award-winning technology.

GFRP pultrusions are corrosion-free - which is of paramount importance in a marine environment. They are highly chemically resistant, including wastewater and petrochemicals, so do not corrode or leach into the environment as do other traditional materials. Pultrusions are environmentally-friendly and have no impact on the delicate ecosystem that exists in marina harbors.

The composite product we have developed for the marinas was designed to include increased creep and fatigue resistance and was designed in a way that ensured it could accommodate the expansion and contraction of the structure without becoming loose.

Other projects we've worked on for the marine sector

  • Seawall reinforcement. Engineers worldwide have realized the benefits of using Mateenbarâ„¢ GFRP rebar in the seawall and other marine applications. It extended the asset life and provides a corrosion-free alternative to steel in the most aggressive environments. This is beneficial to the asset owner and with no concrete spalling it is better for the environment.
  • Undersea cabling in the Indian Ocean, Western Australia. Ocean Technix specializes in difficult undersea engineering projects. Divers stabilized the undersea cabling by drilling holes into the hard rock and inserting GFRP rockbolts held in place by an epoxy resin curing system designed to cure underwater. Neoprene straps were then used to hold the cables in place.
