In the marine industry, dolphins aren’t just gregarious aquatic mammals. The moniker also refers to man-made structures used for berthing and mooring (or docking and securing) boats, ships and ferries. Conventional dolphins consist of anywhere from three to 50 piles and help provide extra docking space when piers are full.
Traditionally, wooden piles have been the material of choice for approach dolphins. For most applications, Fiber Reinforced Polymer (FRP) has usurped wood as the preferred material. FRP breasting dolphins are resistant to the rot caused by constant exposure to sun, salt and water and cannot be inhabited or damaged by marine life. We use larger diameter StormStrong® pilings to produce our dolphins. Given its high strength, a single FRP dolphin can be installed in place of wood dolphins that are made of timber bundles, providing significant cost savings during installation.
Steel or other metals are sometimes used for breasting dolphins as well, but metal approach dolphins suffer from corrosion and a shortened service life. FRP is not impacted by corrosion from water, salt, or chemicals. In addition, dolphins made from FRP are lighter, cheaper and easier to install than metal breasting dolphins. This makes FRP the obvious choice for approach dolphins.
We specialize in breasting dolphins crafted from FiberPILE, which can easily replace clusters of timbers with just one pile––without sacrificing strength or durability. In fact, our FiberPILE dolphins are known for their lower installation cost, better structural performance, and long-lasting lifespan in comparison to traditional mooring dolphins.
