Decoking Hose Failure: A Safety Threat

By C H Anand, Reliance Group of Industries, Jamnagar

There was a near miss incident in our coker unit about a year back. One of our decoking water hoses had failed from its top rotary joint end and fell down on the cutting platform. There was no indication that it was about to rupture (that’s why “near miss”). The hose had failed from its coupling portion due to improper bonding/curing of the glue used. Fortunately, nobody was beneath the falling hose when it failed and a major accident got avoided. We replaced the hose with a new one of another manufacturer, in addition to providing 2 strong safety clamps with chains fastened to the top flange to prevent falling down for the other potential hoses.
