Trelleborg’s marine systems operation has launched a new whitepaper highlighting the impact of the manufacturing process on the performance, safety, and longevity of pneumatic fenders.
Titled ‘Pneumatic Fenders: Manufacturing Methods Matter’, the whitepaper explores the difference in fenders manufactured using the airbag manufacturing method without employing a mold, and fenders manufactured conventionally using a mold, to highlight the impact of the manufacturing process on fender quality.
Pneumatic fenders are extensively used for ship-to-ship transfers mid sea, double banking operations, and as vessel-to-berth at dock/jetties. Therefore it is vital that they are not only of high quality, but are extremely reliable, to guarantee effective performance in even the harshest environmental conditions.
Each and every pneumatic fender must comply with the ISO 17357-1:2014 standard to ensure they follow the correct manufacturing process. The major concern for the industry is that there is an influx of manufacturers employing airbag production methods resulting in fenders that don’t usually comply with all of the recommended manufacturing process guidelines or compound properties as specified under the ISO 17357-1:2014 standard.
By using the conventional method, whereby the entire fender is built inside a mold and vulcanized with it in an autoclave, a clear positive impact is seen on the appearance, dimensional stability and the bonding between layers, leading to a more reliable and long lasting fender.
