From SOYO on Weibo:
But modification to old vessels require major hull cutting operation. IMO currently, maybe only the few final units of 052D built in 155 will benefit from these.
Only Baotou was allegedly retrofitted with CGT-30 (Which could also involve the addition of this shaft generator), AFAIK the batch Baotou was built in was ordered and procured too early for CGT-30 to be certified at the time.

We only know about Baotou. No idea if this shaft generator was part of the modification.
Does the post provided any source of the claim? I ask because there was a patent in 2017 by 701 institute in Wuhan about a electric motor wrapped arround conventional drive shaft. I wonder if they are the same program. Patent is CN107745793A.

Modification of many older ships would mean more jobs for the ship building industry and maybe for docks what have limited orders on books. Keeps workforce active.
CSSC 711th institute with uncommon propulsion. Xuelong-2 boasts installed power capacity of > 24 MW and Mengxiang (a 10000m deep sea drilling vessel) reaches 30MW. Power plant output far exceeds the requirement of conventional ships.
On the Weilai (deep sea research &* test vessel), 711th institute deployed 1000V DC networked electric propulsion system, further reduces energy conversion loss.
so 711th institute developed hybrid propulsion (diesel power generation + BESS) that are on various science research ships. Improves efficiency, noise level, Smart Control and range, emissions and allows you to surge in power for onboard electric demand.
"active vibration isolation, active noise cancellation and acoustic digitalization to further enhance noise reduction level" - this is super cool.
在智能化方面，构建基于数字孪生的智能动力平台，实现智能调度、远程诊断、预测运维 - digital twin technology will be established to enable intelligent scheduling, remote diagnostics, and predictive maintenance -> really cool.

Hengli Group delivered China's first 8G95 liquefied natural gas (LNG) dual-fuel engine, boasting a power output of 74,725 horsepower.
the LNG dual-fuel engine delivered this time is model 8G95ME-C10.5-GI-EcoEGR. The engine body is 16 meters high, weighs more than 1,600 tons, and has a maximum power of 74,725 horsepower . It is currently the most powerful high-pressure natural gas dual-fuel engine in China.
This model is equipped with an exhaust gas recirculation (EcoEGR) system, eliminating the need for external emission reduction devices. It meets the most stringent Tier III emission standards of the International Maritime Organization (IMO) and features safety, reliability, green efficiency, and other characteristics.
Hengli Group said, the first batch of 8G95 dual-fuel engines will be installed on 24,000TEU and 21,000TEU ultra-large container ships built by Hengli Heavy Industry for the internationally renowned shipowner MSC. Currently, Hengli Heavy Industry has started construction on nearly 150 ships, and its new shipbuilding and engine orders are booked until 2030.
Note - Hengli Group is the only second entity in China after CSSC to have capability to design/produce large marine Engines. their Dalian production facility is the single largest Marine Engine production line in whole of China. which has 180 units capacity annually.
