Around the dock
Today was a new composition for Cashman-Testa and continuo -
realign one of the jackup barges's legs; transporting the Mammoet
beams, preparing the Pearman for next week's blast and P-3, known now
as Pain-in-the-Neck
Here is the dock worksite, one of the jackup barges legs
and transporting the top Mammoet beams
Sometimes things become misaligned and in this case, one of the
jackup barge's legs needed a chiopractic adjustment. So a new
section of tubing was welded into place and a rack added to each side.
So the learning link for today is Rack and Pinion gearing - otherwise
known as translating rotary motion into linear motion
Here is a view of one of the jackup barge's legs with a section replaced
The pinion that will be attached to the newly realigned tube
Here is the expert, Joe Perrier, who related that it took the
several months to get the part from Germany, its place of manufacture
Sparky like looking inside things and here he is looking down the barrel that
will hold the jackup leg. The pinions travel down the grooves on either
side and on the right, you can see a tooth of the rack gear.

Meanwhile, out at the Pearman, prep work continues for next weeks blast
Here making a cut to reduce the integrity of the truss structure
and in close quarters
Meanwhile, Michael is working away on P-3
Naming T-3 as tenacity of purpose seems realistic. But because of the
high reach required to bring Grace down, I call this Pain-in-the-Neck
Look how much progress Michael has made - compare with the angle in the
upper boom above with this one.
