If they did I would say it was because there was no alternative at the time and the time it would take to develop a Russian alternative would have delayed the project?
Its quite common. all ships have heat exchangers. Quite common for some ships designed for the atlantic to have to slow down in certain warm conditions.
I am not a ship expert but apart from these faulty British Destroyers I have not heard of that happening before.
The engines actually failed after operating in the Med because the water was not cool enough to keep the engine operating normally... a serious design flaw.
For most ships I would say a refrigeration unit could be used for cooling water as needed and of course food storage would need freezers to be carried on board too, so it should not be a problem on a well designed ship.
All you need is large enough heat exchangers for the situation. Temps are monitored closely and they control the flow to the heat exchangers to keep the coolant at optimum temp. If the temps are high even at max flow, then they slow down . A compelete shutdown should is either design or crew incompetence. The problem was most likely with the AC plant as I think those ships are gas turbine powered and those are air cooled. could also have been cruising on diesel gensets.
