We offer full support at each step from early concept discussions through to design and detailing, material...

Modern tugs frequently use large cylindrical fenders as their main pushing fenders to bow and stern. The rounded section maintains a constant contact against flared vessel hulls, and work just as well with straight-sided vessels. The fender is attached by a chain running along the fender's central bore, and straps or chains in special grooves around the fender circumference. Fender ends may be tapered. TJTB Tug Cylindrical Fenders are available in diameters up to 1000mm (3' 3") and continuous or jointed lengths. Values are for single units, L=1m. Attachment A chain is run through...

The large, flexible faces of M-Fenders exert low hull pressures when pushing vessels. They are grooved for a soft and flexible contact face, which firmly grips the vessel's hull. The M-Fender attaches securely to the tug via fixing pins running through each of its three legs. M-Fenders have a low weight per contact area. They can be fitted around very tight curves, fixed with pins that run through central bore holes. An intermediate support is recommended where length is over 1000mm (3' 3"). Values are for single units, L=1m. Version 001d / Copyright TekMarine Systems LLC, 2015

The Block Fender's instantly recognizable 'keyhole' section handles the most demanding tug operations. Block Fenders have optional smooth or grooved faces to suit different friction requirements, and can be fitted with low-friction UHMW-PE facings for heavy seas. As well as tugs, Block Fenders are commonly fitted to pilings and similar structures to form a simple, reliable protective face. An intermediate support is recommended for fenders over 1000mm (3' 3") long. Dimensions and Fixings Fixing pin Values are for single units, L=1m. Version 001d / Copyright TekMarine Systems LLC, 2015

One of the world's most popular tug fender designs, the W-Fender is built for extreme conditions. Its open-bore profile makes installation simple around almost any hull shape. W-Fenders are fitted using pins that run through central bore holes. An intermediate support is recommended for fenders over 1000mm (3' 3") long. Dimensions and Fixings Fixing pin Values are for single units, L=1m. 54 Version 001d / Copyright TekMarine Systems LLC, 2015

Profile Fenders are used for smaller vessels and lighter applications. They are usually bolted to the structure, either through the top or sides of the fender. Available in various sections including D and square, they can be supplied in almost any length then cut and drilled as needed. Version 001d / Copyright TekMarine Systems LLC, 2015

Q Composite Fenders Composite Fenders combine a rubber body permanently bonded to a low-friction UHMW-PE face pad. The rubber body absorbs berthing energy while the facing reduces shear forces.

TekMarine HD-PE Fenders are durable, low friction strips that wear better and last longer than traditional timbers. HD-PE does not rot, split or suffer from marine borer infestation. HD-PE Fenders are ideal for workboat berths, waterways and lock entrances and as components in larger fender installations. HD-PE is easy to machine and install onto concrete, steel or timber substrates. Better still, HD-PE is fully recyclable after its working life, and is a cost-effective alternative to tropical hardwoods. Fixing HD-PE Fenders are equally at home mounted on concrete, steel plate or beam...

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...

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...
