“hippo” Donut Fenders are circular or doughnut-shaped marine fenders designed to protect vessels and structures during berthing and mooring operations. Typically made from durable materials like rubber or foam, they are commonly used on monopile structures, such as offshore platforms or bridge piers, where they rotate freely around the pile to absorb impact and minimize damage.
Their round shape and rotational capability make them ideal for accommodating varying tidal conditions and reducing friction during vessel contact, ensuring enhanced safety and longevity for both vessels and infrastructure.
