China’s Aircraft Carrier Trouble—Spewing Steam and Losing Power
‘Liaoning’ shut down during recent sea trials

... even if I don't rate David as a highly reliable source, I'm even more surprised that this secret, mysterious "boiler failure" allegedly reported by Sina.com was not even mentioned here before:

...
But on at least one occasion during recent sea trials, Liaoning appeared to suffer a steam explosion which temporarily knocked out the carrier’s electrical power system. The failure, reported by Chinese media site Sina.com, resulting from a leak in “the machine oven compartment to the water pipes.
...
During the accident, hot water and steam began “spewing” out of the engine’s oven compartment, Sina.com reported. One cabin became “instantly submerged in water vapor,” the report added.

The crew immediately evacuated the cabin, with one officer apparently pulling a sailor out by his collar to save him from the extremely hot steam. The carrier then lost power, but the crew “eventually restored power to ensure the smooth operation of the ship.”

Fortunately, this doesn’t appear to have been a catastrophic boiler failure of the kind that would unleash almost instantaneously lethal, high-pressure steam. It’s possible Liaoning instead suffered a low-pressure steam release involving a faulty heat exchanger. Vessels commonly use heat exchangers to control water temperature necessary for regulating internal power and heating.

So, is he simply spinning around a bit or what was the original source of that ???

I'm sure there was some kind of incident on the Liaoning but I think David Axe makes it out to be much bigger then it is. Whatever it is its not seriously enough for the Liaoning to return to port she simply continues her sea trial. Below is the link to the original Sina story. I can't read Chinese so perhabs someone that can, can take a look at it.

The Liaoning has been out at sea for about 50 days now.

According to the Chinese version, it was a leakage from one of the hot water pipes that caused hot water and steam pouring into the boiler room, the said sailor pulled up his own collar (probably to protect himself from the heat) (not as mentioned in English version where he pulled someone by his collar) and rushed into the boilder room to carry out emergency repair. Together with others they managed to restor the boiler power to ensure the ship continue its operation.

Thanks.

That's a much more clear translation and clears things up.

Conventional carriers are complex pieces of equipment. The machinary and propulsion are complex mechanisms and parts of them are going to fail form time to time. The do regular maintenance and the crew is trained in how the components work. When a problem arises, as in this case, the crew attempts to repair it while at sea. in this case that appears to be exactly what happened.

The carrier has been out to sea for over 50 days now. Anything of any major consequence would have brought the carrier home for repairs. If the commander of the vessel, and the commander of the task force it is operating with, and their superiors had any serious concerns for the welfare of the Chinee flagship and its personnel, they would have ordered it back home for investigation and repairs.

That they did not speaks volumes.

It means that whatever happened was not serious enough to stop the ship or its exerciese and they have now repaired it and moved on. They will probably take a harder look at it next time she is in port...but right now, it would have to be viewed as a non-serious inicident.

AAARRRVV! looks like the PLAN is training it's personnel well enough to take action when this sort of mishap occurs. Great job!

This happened aboard USS Hancock (CVA 19) in 1975.

The snipes(engineer ratings) on the Hanna had it really tough in those WWII fire rooms. Man it was blazin' hot down there. Poor old Hanna kept breakin' down..they'd kept fixin' her. Once off of Subic we had just launched the first or second launch of the morning and I was calling in my launch report over the 5jg2(weapons dept sound powered phones) and suddenly everything went black. Hanna had lost all power! We were lifeless in the water. After about 20 minutes the auxillary power plant was fired up and we did have a little power. I guess some sort of engineering catastrophic failure had occurred and the snipes on Hanna could not repair it. The aircraft that had been launched were sent to the beach in NAS Cubi Pt.

It is to my understanding that the CO , Capt. Fred "Field Day" Fellows, was given the choice being towed back to Subic for repairs. Or have some of those Filipino shipyard workers from to get the ship underway so we could get to Hong Kong on time..The Co chose the latter.After the Hanna lost all power it was no showers for two days.. It was hard to get a drink of water except on the mess decks. We could basically just mill about smartly for two days. But guess what?..There was enough water by the time we got to Hong Kong to have Field day..I remember by the time we got to Hong Kong I was really hungry for some real food.. The first thing I ate was some fish and chips.. Later that first day I ate the best steak I ever ate in my life. They kinda fixed the Hanna to get to Hong Kong. We spent 5 or 6 days there. Then limped back to Subic for a lengthy in port period for repairs.

China's Only Air Craft Carrier Is Having Some Technical Difficulties

China has developed some impressive defense capabilities in recent years. But one of its flagship achievements has had some notable technical problems in recent weeks.

As Robert Beckhusen explained at War is Boring, the Liaoning, China's sole aircraft carrier, unexpectedly powered down during a sea trial last week. The vessel "appeared to suffer a steam explosion which temporarily knocked out the carrier’s electrical power system," Beckhusen wrote, citing a Chinese-language media report (which is summarized at Asia Defense News).

Beckhusen notes these sorts of failures aren't unheard of on Soviet-built carriers of the late 1980s — before it was the Lianoning, China's carrier was called the Varyag, and carriers of its class haven't aged particularly well.

"The 40,000-ton displacement Indian carrier Vikramaditya—first a Soviet Kiev-class carrier commissioned in 1987 and sold in 2004 — temporarily shut down at sea after a boiler overheated two years ago," Beckhusen recalls, adding that "the 50,000-ton Russian carrier Admiral Kuznetsov goes nowhere without a tug escort in case her engines break down while underway."

The Lianoning's troubles reveal an important tension within China's defense outlook.

China wants to be a major conventional power. No country goes through the trouble of acquiring a half-operable carrier, or developing simultaneous models of stealth jet, if it doesn't have hopes of becoming one of the globe's leading military powers. Simply pursuing these sorts of projects reveals an undeniable depth of commitment towards keeping pace with the US, which has multiple carrier groups in the Pacific at a given time, and has been developing its own advanced fighter, the troubled F-35, for years.

But China's current military advantages are actually asymmetrical. In other words, capabilities meant to quickly and expediently close the gap between China and the US without having to build up China's order of battle to identical level, even if that means breaking some broadly-accepted rules of how states should behave.

So China's military hacks cyber targets throughout the world, and builds weaponry that few other countries would — things like anti-satellite systems, or missiles capable of carrying nearly a dozen nuclear warheads.

The fact that China even has an aircraft carrier is a reminder that Beijing wants to be a conventional power on par with the US. But the Lianoning's recent problems also show China is still far behind the US as a military power — something that might only make its actions less predictable and more worrisome as Beijing progresses towards super-power status.

From what I hear, boiler problems on large vessels aren't uncommon, which is why there are usually several of them. The report that the ship 'shut down' as a result, however, is of some concern.

I don't think the original post mentioned anything about the ship shutting down.

A few posts back there was a nice translation.

Unfortunately, the folks over at war is boring churn out mostly bad quality stuff that occasionally gets regurgitated by other outlets. Then again, few western news sources bother to check the original chinese source, especially with people that can read chinese.

And the people at Business Insider are quite ignorant. Don't trust what they write.
