Tugs may be fitted with up to four types of fender, tadalafil no prescription each serving a particular purpose. The problem is, as tugs have become more powerful, choosing the right type, size and arrangement has become increasingly critical. It’s now more important than ever to look for ways to increase service life, in order to offset the increased damage that comes with the increased power of the tugs.
To accommodate these needs, we’ve recently developed a new High Performance Super Abrasion Resistant (HPSAR) tug fender, which utilizes an innovative, superior rubber compound. The application of this distinctive and improved compound not only significantly increases the service life of the fender, but also gives the fender a lower density than traditional solutions, contributing to reduced weight and increasing potential savings.
With tug vessels used fenders as bumpers to move larger vessels, they are constantly being pushed against steel surfaces that cause the fender to wear and tear quickly. Common complaints about the tug fenders that are currently standard across the market include the fact that they are easily damaged, heavy, and prone to chipping and chunking.
The improved service life and reduced maintenance requirements of the new HPSAR tug fender highlights just how much rubber compound composition impacts fender performance. In especially harsh environments, such as those in which tug fenders operate, this is essential to avoiding incidents and downtime resulting from when standard solutions fail.
The new HPSAR tug fenders have already proved their value in demanding operational environments, and we’ve already secured contracts to supply the HPSAR fender system to two tugs operating in a port in North Western Australia. The port’s previous solution was chipping, chunking and wearing out quickly in a particularly difficult operational environment.
The HPSAR compound provided a much higher abrasion resistance in combination with a set of very high mechanical properties, meeting the client’s need for a longer lifecycle and reducing maintenance costs. As the geometry of the fender was specified by the client to meet the same parameters as the current solution, the improved performance could be isolated to the superior rubber compound.
It is essential that tug fenders using the new compound are specified by more than simply traditional parameters such as abrasion resistance, tensile strength, tear resistance and elongation at break. With that said, to ensure the quality and performance of the new tug fenders, the chemical composition requirements should be specified. This may include standards for density, polymer percentage, carbon black percentage, ash percentage and polymer to filler ratio.
Rubber compound chemical composition should be evaluated upon receipt of the final product, to ensure that the fenders will perform in harsh conditions over a long service life. As such, we’ve developed a new analytical test that allows our customers to do exactly that.
