New job

[Pete.]

Funny, I never see the guys mooring vessels wearing harnesses.
There is never a safety boat available either as there is always this big ship in the way.
Hopefully they can shut down the props before they become bite sized chunks for the fishes, because that's the immediate risk.
I also haven't heard of many incidents in over 25 years working around ports and harbours.

Being tied on to something, especially with fast moving water, is often the last thing you want and there have been fatalities where the person was using a harness over water.

Do the risk assessment but don't prejudge the outcome.

Same here I never, ever use a harness over water always a life jacket. Fall restraint, yeah on jetty edges etc but that's to stop you going over the edge in the first place. Been on three large projects where welders used self-inflating jackets and never heard of an issue with slag burning through the jacket sheath. If welding can burn through a jacket sheath it can burn through a lanyard and the lanyard will naturally lay on a flat surface where slag collects, a jacket will not.

Also if you're wearing a harness with fall arrest you're obliged to have a rescue plan in place. How would they recover you from dangling in or over water under that structure? Fall arrest is fixed length but the tide goes up and down so you may or may not fall into water and a rescue boat might or might not be able to retrieve you.

Of course you need a rescue plan for working over water in a lifejacket too but at least you have some chance of self-rescue or at least getting yourself to a spot where a boat can get to you plus the changing distance to the water is accounted for.

For me, it's always lifejacket and rescue boat or solid edge guarding.

Work positioning rather than fall arrest is the way.

Glad you’re enjoying the new job Cheesie

Rescue plan is in place Pete for sure, crane on stand by with man basket attached at the ready, never lone working etc etc,

Hmm, well it's a long way from ideal but at least they are doing something.

Your thinking what if the tide take him out of reach of-the crane…..one tires really quickly in cold water even in the height of summer.

There's several good reasons why. A man rider has typically a wind speed limit of 7m/sec. He's on an exposed jetty so the wind will render the man rider inappropriate for rescue for longer periods than not. Also, it takes moments to start a boat motor, minutes to get a man rider into the water. If the guy falls down and manages to get hold of a jetty leg, he ain't gonna let go, he might be frozen with fear or just frozen cold. The boat will get to him under the jetty, the man rider will not.

Just looking after you buddy, and anyone who follows who might have to work over water.

I'm not that person above either, boots on the ground long time experienced.

Not sure on the wind speed you quote but one would assume if winds up, work would stop! In the world Im familiar with the boat would be there, in the water and operational all the time folk are at risk of a swim. Lifejacket and a PLB.
