April 12 2006: Dropping P-11 -> P-13

Sparky was out on the water early this morning. I'll have the photos up shortly.

Off to work at 7:20

and the Chris-o-vator is already at work fetching and toting stuff around the Grace. Here the stuff is a couple of members of the Demolition Dynamics team. Note the charges in place as highlighted by the kevlar wrappers.

Sometimes in the shipping channel, things get a bit tight.

at the sametime - retrieval of Pearman sections and the Jackup barge ready to resume positioning Mickey's guys for drilling C-2

Its 8:10 and more close quarters

A nice view of the East Pearman and Grace Structures

Today's target - the truss spanning P-11 to P-13 with the Yorktown in the background

and our ace photographer, Sparky - set up on the barge

09:59:37.0 according to the EXIF data in Sparky's photos




















After the blast - a view the the results - sort of a tangle around P-12

The half submerged Grace truss between P-11 and P-12

Stan - just taking it all in

Looking from where P-11 used to be

Another view of the section that used to span P-11 to P-12

I don't know how this happened - but here is Nugget, iron worker, like Lewis - aiming a crew boat. And Sonny with a big grin!

And nothing is complete without a view of P-3 - ready for continued unbuiding by Michael. (Happy Easter Tina, Stephanie, Samantha and Joshua - enjoy your family weekend!)

From the Mt Pleasant side - Nice view
