A contractor was performing upkeep on the majority cargo methanol system on deck of a vessel.
What occurred?
Residual water was being pumped out from a cofferdam when a pressurized hose all of the sudden disconnected. The system strain was roughly 5.9-6 bar, creating a possible threat of damage to personnel. Fortuitously, nobody was within the line of fireplace, and no contact was made. There have been no accidents or property injury from this incident.
What went fallacious?
There was no secondary securing system – no whip examine arrestor – put in, although this was specified within the process threat evaluation.
No-one checked the tools earlier than beginning the job.
No-one stopped the job.
The hose finish coupling itself appeared as worn out, and this was unnoticed.
There have been no whip arrestors and hose tail couplings out there, neither on the vessel or with the contractor doing the work.
Classes to be taught
Guarantee there’s adequate tools and spares on board to do a secure job – the shortage of even a really small half can result in one thing being unsafe.
Guarantee pressurised hose connectors have secondary securing – whip arrestors.
Verify your tools earlier than you begin work – it solely takes a number of seconds. Verify the situation of hose finish couplings on pressurized tools, and establish any put on or injury that might compromise their integrity throughout utilization.
