I sometimes enjoy reading the odd MAIB (Marine Accident Investigation Branch) report - all of which, as with their railway equivalent from the RAIB, are publically available - and the issue of poor watchkeeping is a frequent feature. As utterly reckless as it is, it’s easy to see how poor working habits and non-compliance can become commonplace in that sort of tedious, unsupervised working environment. That doesn’t absolve anyone of their obligations of course, but it’s quite evident that there is a sizeable issue within the industry. Ultimately it rests with a vessel’s Master to ensure that appropriate protocols are followed, which doubtless explains why the captain of the Solong has been detained, regardless of whether or not he actually directly crashed his ship.
As for the tanker, it may simply not have been possible to get the vessel mobilised in time to move clear, but I would imagine strenuous efforts to make radio contact or otherwise alert the incoming container ship would have been made, but quite possibly with little chance of success. It’ll certainly make for interesting reading.
