Our latest Barometer Report revealed that the majority (77%) of consultants and contractors don’t know the correct ratio of ingredients in a superior rubber compound for use in fenders.
To me, this suggests a huge gap in specification knowledge and product awareness, and that needs to be addressed. As we’ve talked about frequently in this blog, the performance and lifecycle of fenders vary dramatically based on the type of rubber used, and within that, the compound composition of the rubber.
And whilst many lacked awareness of the importance of compound formulation, what’s more, 50% of those surveyed don’t know if suppliers apply bespoke Velocity Factor (VF). 53% are also unaware if suppliers apply bespoke Temperature Factor (TF).
The application of VF and TF on a case by case basis is essential in determining fender performance and lifecycle. First introduced by PIANC, VF and TF should be applied to fenders depending on the compound composition of the rubber to accurately ascertain performance in the field, under varying compression times and temperatures.
Its no surprise then, that the study also revealed 86% of those surveyed would find it useful to have a system that can easily test suppliers’ compounds. The need is there, and it’s time for suppliers to react to it, evolving offerings to provide the required education and substantiation.
I’d like to get your thoughts on the matter. Do you feel that the level of knowledge within the industry is up to scratch when it comes to specification? Let us know in the comments section.
