It’s not intentional. They screwed up the ship and nobody wants a damaged ship full of enormous amounts of explosive material in their port.

The ship has been seeking a port for it to dock in as it is in need of repairs, having cracked its hull after previously running aground.

Jens Wenzel Kristoffersen, a defence analyst at Nordic Defense Analysis and a former naval officer, questioned why the ship had not been ordered to return to Russia.

He said that its condition and cargo posed an environmental and health risk.

“One can question whether it is at all justifiable for the ship to be allowed to sail. There are several reasons for this,” he told Danish media. “It has cracks in the hull. It has rudder problems. It can no longer sail by itself, but must be towed.”

He added: “This is a ship that nobody wants, but that nobody can get rid of.”

That ship in Beiruit had similar issues – it wasn’t seaworthy, so wasn’t allowed to leave, and the owners just abandoned it in port, where (a) all the ammonium nitrate was offloaded and the port authority in Beiruit had to deal with it and (b) the sunken hull.

MV Rhosus was a general cargo ship that was abandoned in Beirut, Lebanon, after the ship was declared unseaworthy and the charterers lost interest in the cargo. The 2,750 tonnes of ammonium nitrate which the ship was carrying was confiscated and brought to shore in 2014, and later contributed to the catastrophic 2020 Beirut explosion. The vessel’s owner at the time of abandonment was Cyprus-based Russian businessman Igor Grechushkin. The ship sank in the Port of Beirut in 2018.

The ship is still blocking Beirut port space.

I think that a likely better concern is less that the thing is going to just blow up after reaching port – though I did read an earlier article pointing out that if repairs require welding, that it’s a risk – and more that it might wind up abandoned in port like the other ship.
