She is about the only warship left in active service which has "old school" water tube steam boilers, same as you would find in a coal power station. When the boilers were constructed just after the collapse of the Soviet Union she was built with poor quality steel in the water tubes and this has resulted in poor performance and frequent boiler tube leaks, requiring the boiler to be cooled and repaired, a process which can take days. It is also why she is so smokey due to the heavy fuel and incomplete combustion - a gas turbine would burn light fuel much more cleanly. Apparently during this refit there are going to be changes made to the propulsion system, but given the extent of the work required to completely replace the boilers it is likely to be nothing more than new tubes and better burners, so she could be smoking her way across the world (with tugs in tow) for another 25 years yet!
ETA for return to service is H1 2024 with a life expectancy of 25 years, unless the Ukrainians find it first.
I'd heard there were reports of putting gas turbines in, but the whole powerplant configuration (locations of kit etc) would be very different. To do it would need a huge amount of the ship cutting out and reconfiguring, I just don't see how that is possible in 18 months. More likely they bodge what is already there and carry on with an improved and more reliable conventional boiler arrangement.

Indeed; just doing a basic refurb of the boilers and engineering plant would be enough for the claimed objective of returning to service in 2024. There is no time for anything more involved.

"Here are upward pointing fairwater planes seen on a boat that just surfaced through ice. At any angle other than horizontal, the ice adds weight to the planes which they are not designed to handle and can get damaged,. Vertically, minimal weight ant and force is added while breaking through thanks to the smallest possible area of contact and this kinda helps break the ice as well."

Here’s one I made earlier.
12 year old VLCC M/V Bourgogne converted into PSVM FPSO at Jurong Shipyard Singapore by MODEC for BP at a cost of US$2bn. She’s turret moored in 2000m of water offshore Angola.
One year I stayed 132 nights in the Shangri-La hotel on Orange Grove Road and had ALL the air miles and hotel loyalty points. The good old days in O&G.

This is far more difficult and complicated than I had imagined - Destin (Smarter Every Day) explains - "Here are upward pointing fairwater planes seen on a boat that just surfaced through ice.
