Marine Fenders

About TekMarine From its base in the United States, TekMarine Systems LLC designs and supplies advanced marine fendering and mooring systems to ports, harbors and waterways across the world. We bring a wealth of engineering and market experience to each project. Our fender solutions range from simple modules to the most sophisticated engineered systems. We supply every type of berth, including passenger terminals, bulk and RoRo ports, Oil and Gas installations and naval facilities. We offer full support at each step from early concept discussions through to design and detailing, material selection,...

Design Considerations Weight support Chains can assist in controlling the compression geometry of fenders in some applications. Please ask TekMarine for more details. Fenders can support large static weights. We recommend weight support chains for panels heavier than the rubber fender. FV When the tension will exceed the fender’s rated reaction force, then tension chains are strongly recommended. Fenders remain stable with vertical or horizontal shear forces. Shear chains may be needed for some applications and fender layouts. Clearances TJCO Cone TJSC Cell Fenders should not contact each other...

Rubber Properties Every TekMarine rubber fender unit uses the highest quality Natural Rubber (NR) and/or Styrene-butadiene (SBR) based compounds. These meet or exceed the performance requirements of the main international fender specifications such as PIANC and EAU-E 62 "Acceptance Requirements for Fender Elastomers". The table below shows typical specifications for laboratory prepared and tested specimens. Please consult TekMarine about other fender compounds such as EPDM, Butyl, Neoprene and Polyurethane. Material samples for laboratory test purposes are prepared differently to rubber fender...

Standard manufacturing and performance tolerances apply to all TekMarine fenders. TekMarine may agree to smaller tolerances in special cases. Please ask TekMarine for tolerances of types not listed below. Unless otherwise listed or agreed with TekMarine, tolerances are ±20%. Version 001d / Copyright TekMarine

Testing Testing of molded1 and wrapped cylindrical2 fenders is conducted in-house, with an option for third party witnessing, using full size fenders in accordance with the PIANC 20023 guidelines below. All fender units have a unique serial number which can be traced back to manufacturing and testing records. Fenders are tested under direct (vertical) compression using the Constant Velocity (CV) method. The test specimen shall be broken-in by deflected three or more times to at least its rated deflection. After break-in cycles the fender specimen is allowed to recover for at least one...
