I read a while ago .... the reason was the Russian propulsion engines (steam turbines) were not reliable to go that far. So only around the coast of China


Neither did the Type 051C ever made those missions, but I don't know if that has anything to do with the engines, considering that the Type 051B did one escort mission, and up to 10 years prior to that, worked as the PLAN's ambassador going around the world.

The last exercise I know the Sovremennyys conducted was around March 2018, involving 138 and 139.

051Cs never went because they have no hangar. The PLAN thought about at least giving them sustaining capabilities like refueling and maintenance so they could go to Somalia with helicopters but ultimately it didn't happen.

The Sovremennyy class also doesn't have hangers. Bingo.

It doesn't look like it can pull the entire helo in.

The rotor of Ka28C can be folded (backward). No problem in putting that helo in.

-- Nevertheless, it's indeed reported that Sovremennyy class' hangar design is poor in helo operation/maintenance. And helo had been very critical to the escorting mission in India ocean.

On the other hand, it's also said that fuel efficiency of Sovremenny steam turbine is the main issue stopping it sent to escorting. Same issue also happen at 051B, which been only sent once (2009). Again, that's all I can find on web.

138 and 139 have a redesigned stationary hangar. The biggest problem for a helo on 956 is the launch pad too close to engine exaust which causes a lot of turbulance.

Regarding the fuel effciency of 956 it should be on par with earlier Soviet designs like 1134A Kresta-2 class which has essentially the same powertrain. Krestas were used by all Soviet Navy fleets and were real workhorses of the Navy.
Two main problems with the 956 powetrain were identified - extremely sensitive and complex automated engine control system which had reliability problems and required high level of training of engine teams and overcharged boilers requiring very high quality of water. Both problems were accerbated by Soviet conscript system and general decline of education system and simple lack of money for timely maintenance and repairs.

The improved hangar facility on the 138 and 139 came at the expense of loosing the rear AK130 guns
