Good afternoon all,
I was looking for some advice regarding Working at Height and wondered if anyone can help?
It is well documented that the Port & Dockyard industry is notoriously dangerous due to the operations that are undertaken, and risk of injury is high if the hazards are not appropriately managed.
I am currently in the process of changing working procedures at my place of employment and one has caused me some concern.
As part of our Forestry Products operation, we handle large volumes of news print paper reels. Normally these reels would either arrive via containers by road or by conventional Ro-Ro vessels (roll on & roll off). However occasionally the reels will arrive as conventional breakbulk cargo within the hold of a vessel.
For those of you who are unfamiliar with such terminology, imagine a ships cargo hold with paper reels stacked end to end from the bottom of the hatch to the top. As these reels are circular there is a gap between each stow of four which falls the entire depth of the hold, up to approximately 80 feet!! (imagine four toilet tubes grouped together side by side.......You get the idea.
Unfortunately the discharge of such cargo is only possible via placing an expanding probe into the reel's core which enables it to be lifted once the prob is activated, however human intervention is required to guide the probe into the reel core, thus meaning that the operative has to stand in the vicinity of the drop between the paper reels.
Are you following so far?
The main problem I have is preventing the operative from falling between the stacked reels.
The operative is required to the operation as it is imperative that the probe is guided and activated once in position.
Most of you I'm guessing are thinking either harness or safety nets, however due to the way the reels are tightly stowed within the hold, nets cannot be used, likewise due to the overhead lifting equipment that is in operation a safety harness cannot be attached over the hatch opening via a guide wire, and unfortunately the internal structure of the hold itself is smooth steel from top to bottom (imagine the inside of a box) so there is nothing inside of the hatch to connect a harness to either.
As you can see, this is not an easy one to clarify.
I have amended the risk assessment and provided the area supervisors with a relevant Tool Box Talk to ensure a safe system of work is agreed and maintained before and during the operation, however I must prevent the fall should one occur.
We currently have walking boards in operation however these need to be constantly moved while discharge is in progress and it is not a permanent measure to prevent a fall.
If you guys out there can offer any guidance I would be grateful for a response
Best regards, Kai

My first comment would be why have anyone in the hold at all. You say that someone has to activate the lifting mechanism. There are many cranes in which the activation is done by the crane driver from the comfort of his cab (pneumatic / hydraulic / electrical).
To me that is the way forward.
As an alternate, a remote control operated from the hatch coaming, again, nobody in the hold. We use a crane on our vessels with just such a radio control - keeps the operator well clear.

Agreed Colin, and CCTV if there are issues with visibility, sight-lines etc. Camera could be mounted on the lifting gear.

Thanks for the response Colin,
The lifting gear is attached to a rail mounted gantry crane that is positioned on the deck of the vessel.
Each probe is attached to the frame via a heavy duty chain, which makes positioning the probe into the core like hitting a bullseye every time at darts..... and as the frame lifts 10 reels at a time it would be impossible to land the rig and core all 10 reels at once due to any variation in the reels position or a swing on the probe.
Does that make sense?
I like the idea of the automated locking mechanism
Thanks Colin

Ahh, much clearer now. Not an easy one to get round as the crane is ship's equipment - presumably foreign flag?
Also walking boards I can see are difficult, have used 8x4 plywood which gives greater area, but with a grid that, I presume, requires getting inside to line up the inner cores, large boards would not work either.
Thinking cap back on!

perhaps not possible but contact the loading organisation and mandate the rolls be loaded length ways, eliminate the risk at source!

Now moving beyond my own knowledge sphere which is primarily ro-ro. However, I would suggest contacting the industry body who may be able to advise:

Morning Colin,
Yes, you are correct, the crane that is utilised is ships gear.
We have walking boards in place at present however the constant movement of them is not ideal.
Thinking caps indeed!

what about a harness attached to a fall retractable wheel(with long enough wire) and attached in turn to the lifting gear itself

Thought of that as a suggestion, but the fact seems to be that the stevedore has to move around under the lifting frame across the ten reels to ensure each is correctly aligned. This is a large area - could be 20+ feet of movement so a single anchorage would cause movement difficulties, possibly introducing more risk than countering.

What about a portable harness point that slides into a reels core with a collar to stop it falling through so the stevedore can clip in, we use similar portable harness point that can attach to a containers twistlock casting when we need to work on containers as the reels are probably more than one ton each it is a sufficient anchor
just an idea

I work in a Newsprint papermill and webs that me make for export to USA are sent to Tilbury Docks and loaded into the ships hold in the format you have described. The difference with their loading technique (and our preparation) is that our webs are wrapped with a protective cardboard wrapper on the body and sturdy cardboard headers on both ends. Crucially one end has a hole in the middle of the header (top end, adjacent to the core) and when loaded the web is lifted via vacuum. Several of these webs are lifted at one time via a carousel by sucking the air out of the body of the webs and cores and then lifting them into the ships hold. The same removal process is employed in America. For obvious reasons it is imperative that tight production controls are maintained at the mill to ensure the correct materials are used during the wrapping process and the integrity of the wrap is 100% secure but this loading process removes the need at source for persons being required to enter the ships hold to monitor the loading/unloading process as you have described. Obviously this may not be a quick fix for you but it could stimulate further discussion knowing that the technology is out there to avoid working at height at source which is always the 1st step on the hierarchical ladder.
