Can't recall this being reported at the time, but understand why not when the entire crew of 70 were found dead at their posts. Still no real answers other than some logical reasons as the why this disaster occurred. Sorry about the annoying robot voice-over which seems to be becoming the norm these days.

Someone in the engine room got tired of restarting the engines after the head valve got dipped and the high vacuum cut out had stopped the engines. The cutout was over ridden and the boat pulled a vacuum and killed everyone. It was a Russian boat given to China. They had a 30% buoyancy so the thing just floated to the surface and bobbed around until discovered by a fisherman. |

Could also have had an engine run on and filled the boat with exhaust gases. Easy for the authorities to determine; we must applaud the Chinese for their detailed honest explanation. Funny about that! |

Chris,that may just be what happened but it was so fast that no one had time to move. A diesel can suck all the air in less than a minute. The men were found at their stations. They passed out from no air. But, I have never read the Chinese report. |

Monoxide poisoning can also happen very quickly.
We would need an ex-Romeo man to inform us of the time period to start and possible vacuum that could be drawn by that engine grouping. Some boats had an automatic shutdown if the vacuum got to a certain level. Know very little of boats older than the Foxtrots. |

It was the high vacuum that was suppose to have been tampered with. |

The boat must have ben snorkeling otherwise the high vacuum trip isn't in the circuit.
On Entemedor a Guppy IIA conversion, in addition to that trip, there was also the high back pressure in the exhaust system trip.
The high vacuum trip was set at 6" Hg. It would shut down the engine(s) in about 15-20 seconds after head valve closure. about the same time as your ear drums started hurting badly.
We 'enjoyed' lots of 'flameouts' when snorkeling in rough water.
I think the engine would have died from air starvation first, but having depleted the air in the boat, the troops were 'dead meat'.
Looking back if this is really what happened, think of the lives that were dependent on a lowest bidder pressure switch on our boats. I guess we were lucky.
