M/V Arvin breaks in half in black sea waves.

Forty six (46) year old river cargo ship/ coastal freighter breaks in half in Black Sea, around one kilometre (1 km) from the coast. Of the twelve (12) crew, six (6) were rescued, and six lost their lives (3 recovered, 3 lost). This happened on the 17th January 2021.

The ship was at anchor due to a storm and pointing into the waves (best practice).

Sailor uses expletive “Piz” moments before the wave hits.

Пиздец/Piz-dets

Literal meaning: damn it

How to use it: Another word hailing from ancient language; its original meaning of ‘vulva’ distorted over time. It is among the words that have existed in the Russian language for almost as long as the language itself. Pizdets is the general description of a situation that went very wrong, so it can be used on its own as an exclamation or in a sentence: Vot eto pizdets!

As can be seen this ship broke across it’s width at a point along it’s length. The ship structure is similar to a beam, but with sections of the beam welded together. The ships weight is usually supported by the water, the ship can’t support it’s whole weight with the cargo. As the boat raises and falls In the rough sea the ship is a bending beam, large fluctuating loads are possible, failure occurs when the load locally surpasses the strength in any of the joints. This can lead to increased load on other sections. In service, the ship has been subjected to fluctuating loads (fatigue loading) and will also have corroded. Of course, over it’s life, inspection and repair will have occurred, but it’s not easy to know the residual strength or the loading that occurs on the ship.

When a weld breaks on a ship, it can quickly propagate, it propagates at a speed close to the speed of sound in the metal. In steel the speed of sound is 10-20 times the speed of sound in air, depending on the type of sound wave.
