To choose between a chain-through, cylindrical, and pick-up offshore mooring support buoy, start from the load path: if the mooring chain must pass axially through the float and share tension, specify a chain-through buoy (CTB); if the chain or hose attaches to end fittings and the buoy only lifts a

ISO 17357 pneumatic fender sizes are the nominal diameter × length combinations (in mm) defined for floating pneumatic rubber fenders under ISO 17357-1:2014 (high-pressure 50 kPa / 80 kPa grades) and ISO 17357-2:2014 (low-pressure ≤7 kPa grade). The most common catalogue range is Ø500 × L1000 mm up

What Is UHMW-PE Facing Fender Pad? A UHMW-PE facing fender pad (Ultra-High Molecular Weight Polyethylene facing fender pad) is a thick, machined plastic sheet fixed to the front face of steel fender panels, rubber fenders, lock walls, bridge buttresses, and jetty structures. It acts as the low-frict

If you’ve ever watched a large ship dock, you’ve seen the silent workhorses that make it all possible: rubber fenders. Among the many types available, the D rubber fender (often simply called a “D fender”) is one of the most common and versatile. This guide explains everything you need t

How Shipyards Choose the Right Marine Airbags: Step-by-Step Selection Guide Choosing the right marine airbags is the difference between a safe 2-hour vessel launch and a hull-damaging, insurance-triggering failure. Modern shipyards no longer treat ship launching airbags as commodity rubber tubes—the

Pneumatic vs Foam Fenders: Which Marine Fender Actually Fits Your Berth (2026 Guide) Choosing between pneumatic and foam-filled fenders is not a spec-sheet footnote—it decides how much downtime, puncture repair, and hull-pressure risk your port, yard, or offshore project absorbs over the next 10 yea

What Is an Arch Rubber Fender? The Practical Engineer Guide (2026) An arch rubber fender is a solid, arched-cross-section marine fender mounted on quays, pile dolphins, lock walls, or vessel hulls to absorb berthing energy and lower reaction force during docking. Its curved profile spreads impact ac

Quick Answer: What Is a Cone Rubber Fender? A cone rubber fender is a high-performance marine fender with a conical shape that absorbs massive berthing impact energy while exerting low reaction force on both the vessel hull and the dock structure. Its unique truncated-cone geometry allows it to defl

Understanding Marine Equipment: A Practical Guide to Types, Systems and Specifications Understanding marine equipment starts with one idea: every item bolted, welded or cabled onto a vessel exists to solve a specific problem—move the ship, keep it positioned, navigate safely, fight fire, handle carg

Where Foam Filled Fenders Are Specified: Application Map for Ports, STS and Offshore Berths Where foam filled fenders are specified is a practical question for every marine engineer, port planner or procurement officer who has been burned by a punctured pneumatic fender or a deflated STS line. Foam
