So far so interesting, and it makes a nice story for the press to cover at what is normally a quiet time of year.
The question we should be asking is "Who is going to pay for it's disposal?"
The answer is: the Comhairle.
At present neither the shipowner, the customer, nor the supplier have any responsibility for anything lost overboard (although they can be liable for losses caused by the flotsam) and aas a consequence, once it is off the ship, nobody cares about recovery, removal or cleaning. Except the local authority who have to do the clean-up.
Last year, there was a proposal to add responsibility for losses from ships inside the EU back onto the shipowner (and they would presumably provide loss insurance for the customers), to ensure that funding for beaches and seas to be cleaned could be simple and clear.
Unfortunately, the UK (egged on by the shipping industry) vetoed this proposal, and the opportunity to pass this into law was lost. All of which explains why the shipowners never notified the Coastguard (or Lloyds?) of the loss - when, where, how? - as they have no obligation to do so. Indeed, doing so might create an obligation on them.
If we want to legislate against dropping litter on streets, why do we allow this kind of fly-tipping to continue?
