Entitled ‘Pneumatic Fenders: Manufacturing Methods Matter’, the whitepaper explores the difference in fenders manufactured using the airbag method without employing a mould, and fenders manufactured conventionally using a mould.
Mishra Kumar, global technical director for marine fenders at Trelleborg’s marine systems operation, said: "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 mould and vulcanised 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,” he said.
