New Theory For Foam Fenders


Trelleborg’s Marine Systems (TMS) has launched a new interactive whitepaper that recommends a new testing method for foam fenders and features an on-demand webinar that outlines a new best practice approach for design and manufacturing.

The whitepaper, ‘Smarter Foam Theory’, focuses on performance testing and advises that the engineering data reported in manufacturers’ catalogues is based upon common testing methods throughout the industry.

The company warns that this is especially important in the absence of the World Association for Waterborne Transport Infrastructure (PIANC) guidelines on foam fenders.

In the webinar, Kumar, Trelleborg’s materials expert, explains the results of the research program in more detail, and how specifiers can use this new data to aid foam fender specification going forward.

The whitepaper states: “To pass the Quality Assurance test, all fenders in the sample must meet 90% of the energy (CV test) before exceeding 110% of the reaction force at any point during the second compression”.

Trelleborg’s latest research into the characteristics of foam, and the way foam fenders are tested, has revealed that a full size fender or an equivalent model fender should be “compressed four times successively and rested for 24 hours”.

Mishra Kumar, Technical Director for Marine Fenders at Trelleborg’s marine systems operation, said: “Foam fenders are an extremely versatile solution, often the most effective system for a number of applications.

“However, the specification and production of foam fenders needs to be taken more seriously, to give facility owners and operators reassurance when specifying foam for the most demanding and critical applications.”
