Can you present the link for us to get more info?

The maker of the mobile hoist is ZPMC Shanghai Zhen Hua, the same supplier of mobile hoist for British shipyard building the QE class aircraft carriers.

11月24日,江南造船(集团)有限责任公司1600吨龙门吊主梁吊装到位,标志着整台龙门吊总体吊装顺利完成。该节点的完成为2016年3月18日的按时交机打下了坚实的基础,在船舶行业龙门吊的建造过程中具有里程碑意义。
据了解,1600吨龙门吊于2015年6月8日开工。为确保整台龙门吊的建造质量、进度可控,江南造船成立1600吨龙门吊专项建造组,每周组织建造方、监理方召开协调会,对建造过程中出现的各类问题及时协调解决。
1600吨龙门吊作为目前国内起重量最大、起升高度最高的龙门吊,此次总体吊装采用的三大件(主梁、刚性腿、柔性腿)总装方案中,170米主梁采用5000吨浮吊偏中心吊装,主梁与刚性腿对中精度须控制在2毫米之内,要求之高、难度之大堪称“刀尖上的舞蹈”。针对“1600吨龙门吊总装方案”,建设工程部多次组织大型设备吊装、起重、船务等方面专家进行讨论和评审。同时,为切实履行安全监管责任,建设工程部11月13日组织上海船厂船舶有限公司及行业内大型设备吊装方面专家召开了“1600吨龙门吊总装现场安全评审会”。安全评审当天,行走机构吊装。针对评审中发现的问题,总体吊装前要求振华重工逐项落实,以确保总装过程万无一失。
因1600吨龙门吊总体吊装期间除影响江南造船4号船坞生产,同时还影响上海江南长兴重工有限责任公司3号船坞的生产,为确保1600吨龙门吊总装如期顺利完成,在江南造船有关领导的带领下,建设工程部对外紧盯主梁、刚柔性腿、上下小车等部件的建造进度和质量,对内通过公司领导、生产管理部积极与兄弟单位协调总装窗口时间,最终确定在11月15日4号坞在建船舶出坞前,完成1600吨龙门吊大车行走机构吊装,11月17~25日间视天气情况,依次完成刚性腿、柔性腿、主梁的吊装。在各方面工作准备到位后,11月21日刚性腿吊装到位,11月23日柔性腿吊装到位,11月24日主梁吊装到位,1600吨龙门吊创造了4天完成总体吊装的历史记录。
1600吨龙门吊总装完成后,接下来近4个月内还要完成电气接线、调试、试车、型式试验、取证等工作,后续大部分工作都需在95米以上高空完成,难度系数大大增加。建设工程部将在后续工作继续严抓质量和进度,力保2016年3月18日按期交机。

While the 1,600 tonnes mobile crane is under testing prior to hand over on scheduled March 18th next year, Jiangnan Shipyard has posted on their official website recruitment page showing 2 particularly interesting positions for "Nuclear Propulsion Fitting and Installation".

From Henri K Dual use submersible normally use to carry top side of drilling or production platform But can also be use to carry military ship or pallet

Three months after the commissioning of the second largest submersible in the world with a capacity of 98 000 deadweight tons, China added a few days ago a small displacing more than 50 000 tons Existing fleet of these giants of the sea.


The particularity of this Zhenhua 33 is that it is dual-purpose, meaning that its design and construction take military standards into account, so that it can be used by the Chinese army if the need arises . It is also the largest Chinese civilian ship that meets military requirements.

According to the presentation, this semi-submersible, in "military" mode, can be used to repair and repatriate damaged warships, refuel the helicopters on its large bridge like a soccer field, or turn into a logistics center For ships that move up to 10,000 tons. These military uses are not limited only to the Chinese navy but also to other corps, such as the army, for example, during amphibious operations.

The Zhenhua 33 measures 227 meters long and 43 meters wide, its main deck is 7,700 square meters. The semi-submersible is equipped with a total of six diesel generators, four of which are used for electric propulsion of the ship. It can reach a speed of 14 knots, and can maintain its position dynamically thanks to a DP2 control system. The ship's autonomy is 18,000 nautical miles.

Built by the Qidong Shipyard near Shanghai, the ship was put on the water on June 18, 2016 and completed all its sea trials on February 27, 2017. The total cycle, from design to entry into service , Lasted two years and three months.

Apart from this semi-submersible civil-military, the Chinese navy has already admitted to service another semi-submersible that is 100% for military use in July 2015.

The 886 Donghaidao is the first of its kind in China's naval forces and moves more than 20,000 tons. It has already been used to transport the Zubr hovercraft, which makes it possible to extend the range of action of the latter.

The semi-submersible 868 Donghaidao of the Chinese Navy

The construction of this kind of auxiliary vessels gives an indirect glimpse of the extent of the expansion of the Chinese navy, which is no longer in doubt (see our dossier "

" . In addition to counting how many more aircraft carriers, destroyers and frigates have been built, it is equally interesting to monitor the gradual expansion of these support vessels, which play a vital role in the smooth operation of offshore operations. A navy.


To be continued.

Upon reading about ever continuing drops in orders for China's shipbuilders (And Korean, Japanese etc) where the number of shipyards that've gone out of business has gone over 50% in the last several years, I am inclined to think that the recent (last few years and a few more years to come) push in PLAN's newbuilt assets may in large part be due to government wanting to give some work to the shipyards so it helps them survive.

Corraborating that idea would be previous rumors of PLAN not really desiring 001a nor such quick adoption of 055, etc...

Not really.

You have to realize how big China's shipping industry is before you realize that military ship-building is a very small portion of the industry capacity, no matter how much more to ramp up or how fast track the military ship building.

China has thousands of ship yards; naval ship building is only limited to less than 10 elite, state-owned ship-yards. The rest of the shipping industry is unlikely to benefit much from naval ship-building.

I also doubt China would base its strategic naval force planning and scheduling on surplus civilian ship building industry. And, programs like 001A and 055 were planned years ago, not some haste last-minute decision to salvage "struggling" JNCX or Dalian. China has excess ship-building capacity; hundreds of yards, particularly the privately-owned ones building low-tech civilian ships, have gone out of business in the last few years. They should be let go.

from pop3 dated October of last year reveals some interesting trends and price figures for various equipment and vessels of the PLAN.

  • As a rule of thumb, due to increased wages, increased technological sophistication, and inflation, ships of the PLAN have gotten more expensive. However, they are still extremely affordable compared to OECD averages.
  • A Type 053H3 built in the late-90s cost 478.5 million yuan whereas the same type built in the 2000s cost 550 million yuan. It's important to note that although the vessels share the same designation, later builds incorporated improvements over the earlier vessels.
  • The Type 346 APARs on the Type 052C and Liaoning cost around 500 million yuan per set, comprising a significant portion of the destroyers' total cost. The Type 364A costs even more.
  • The original Type 054 FFG and Type 071 LPD both cost around 1 billion yuan per vessel. I always wondered how the PLAN could justify skimping out on CIWS for the 071s since I assumed CIWS cost would comprise a very small portion of the total. However, with this pricing revelation, while I can't fully agree with skimping out on CIWS, I can see how the cost differences would be significant enough to compel the PLAN to opt for the far cheaper H/PJ-13s.
  • The initial dual-barrel 100mm guns mounted on Type 051s and Type 053s cost a few million yuan but by the last few examples, the cost had risen to over 10 million yuan.
  • The basic Type 056 costs 670 million yuan, while the Type 056A, with the addition of the Type 311 TAS, costs 710 million yuan.
  • The Type 055 costs 6 billion yuan.
  • Overall, cost management of the PLAN is a balance of public and private interests. Profit margins for the relevant industries are guaranteed but also limited; usually around 5%. More tightly controlled than cost is quality. The PLAN is absolutely anal about QA and those found knowingly subverting QA procedures and standards are subjected to criminal charges, the punishment for which includes the death penalty.

Overall, this post doesn't entail too many surprises. Probably the most unexpected for me would be the cost of the Type 071s, at 1 billion yuan. I'd assume the 1 billion figure is given for the first 071, as it is a contemporary of the original 054s, which was also said to cost 1 billion in the very same sentence. Therefore, it's likely the newer 071s would cost somewhat more than 1 billion due to improvements in various subsystems and inflation. It's quite clear that surface combatants cost the most as advanced sensors, electronics, and weapon systems comprise a massive chunk of the total vessel cost while hull construction costs are limited due to sheer efficiency and economy of scale of the Chinese shipbuilding sector.
