‼️ "Obukhov" choked - another Russian ship was disabled

👉 As a result of the successful operation of the GUR of the Ministry of Defense of Ukraine, the minesweeper of the Baltic Fleet of the Russian Federation "Aleksandr Obukhov" was disabled.

🛳️ The ship, which was based in the city of Baltiysk and was supposed to go on combat duty, suffered severe damage - due to the mysterious appearance of a hole in the gas pipe, water got into the engine: "Obukhov" choked.

✔️ Now the Russian minesweeper is undergoing major repairs, and this may turn out to be a serious problem - the damaged M-503 engine is a rare thing. Repair of a key installation on a ship is technically difficult and expensive.

❗️ It is interesting that the decommissioned enemy ship very recently, in July of this year, underwent repair work in the city of St. Petersburg.

⚡️ "Obukhov" is already the second neutralized ship of the Baltic Fleet of the Russian Federation in the last six months.

☝️ We will remind you that in April 2024, as a result of the Rybalka operation of the Ministry of Defense of Ukraine, the missile boat "Serpukhov" was disabled .

Might be showing the tiny hole in the gas pipe that allowed in enough water to seize the engine? Just a guess. I don't know a lot about marine engines, even less about Russian designs, but water does not compress and can absolutely destroy an engine. The combustion chamber in a gas engine is where the mixing of air, fuel, and sometimes oil occurs. A piston rides inside that chamber under tight mechanical tolerances. If you allow water into the mix, and the piston attempts to compress that along with the fuel / air / sometimes oil, you get a situation where the water won't compress so something mechanical in the engine will. Can cause piston connecting rods to bend / break, can cause combustion chamber or sealing ring damage, can throw the engine out of time and cause issues on the valve train or crank shaft, sometimes even drive shafts. Would usually mean a full engine rebuild, and could mean an entire new engine block. Not an easy thing to fix.
