Earlier articles had WSDOT talking to the operators and telling them they thought it was operating at too high of temperatures awhile ago - weeks before it hit the pipe and then a few days later was stopped.

But WSDOT was saying how they can only make comments, as the STP owners are the folks that make the final decisions (and therefore remain liable).

The “bad sensor” thing might be correct, but it reminds me of the failed gas line and explosion we had north of Seattle due to a “bad sensor software”. Had to do with the Y2K changes in software. After so many false alarms going off about a closed valve on a major gasoline pipeline, the operators ignored it. It WAS close, the thing ruptured and blew up, kill two people in a county park.

Sorry for the aside, but I hope if they think it is the sensors they replace them or troubleshoot them. And not try the old “Oh - ignore that, it is just a bad sensor” thing!

I can’t imagine - being stopped for almost a month now (since Dec. 6) and only going 800 feet or so. I wonder what surprises are in store for them the remaining x thousands of feet.

Catch me if you can and tame the beast
Should I leave you burning in the heat
Kick the throttle down, I’m on fire
It turns me on to feel the engine’s beat

Take it to the highway on the open road
I want to feel your power
Screaming into overload
She’s running hot, she’s hot

Coming out of nowhere, moving fast
I gotta keep the feeling
Make it last, met me feel your body
I’ll explode, together we will run to overload

Take it to the highway on the open road
I want to feel your power
Screaming into overload
She’s running hot, she’s hot

Reminds me of the movie Used Cars when Mickey takes Luke Fuchs out for a daredevil ride in Luke's best car.

Giving Luke a heart attack.

Running hot! REAL hot!

I don’t think it is love though something is in heat. I think Bertha is knocking at the gates of Hell or a Volcano. Either would suit for Seattle.

I have done tunnels under most major cities, Paris. London, Sidney, Chicago, New York Boston and Seattle. I worked with the Japenses(Komatsu) building machines a couple TBMs. I looked at the head, and it looks OK, so I am thinking a design - quality problem with the main bearing and drive system.

I wonder if they designed it to drill bore holes ahead to determine if anything nasty is coming up?

You made me read shibumi’s about page and you are 100% right. Maybe even 110% right.

Getting close to a deep fissure filled with magma?

I hope not. If so, I'm glad I live 30 miles away at 550 feet elevation.

Jeff should keep his mind on the drilling he is paid to do.

Not the drilling he hopes for.

Has anybody checked the oil? Probably some union guy was supposed to take a can of 3-in-1 oil and squirt a little on the gears but was too busy trying to sign up of CommieCare!

If Manitowoc had built this machine, the hole would be done and they'd be washing down the digger for its next assignment.
