Normally, I would just add the first photo below to tandem lifts. But John provided enough photos in the posting's comments that it is worth its own posting. These photos provide some insight into the expense of drilling offshore ore wells.

The initial photos and comments are from a John Katok posting. Francis Letecia Reyna Pawelek also contributed to that posting.
John Katok One night we were setting one of the 8 main piles ( 54" diameter x 2-1/4" wt, x 1000 foot long, about 625 tons, with a Varco elevator, and that elevator sheared across its 11" x 11" cross section and sent that main boom into the sky, and rocking back and forth like nothing I had ever seen, thought we were going to get showered with boom, it was one of those defining moments. Luckily the boom checked out okay and we continued on. Varco had to do some explaining though.
Calvin Hutchins How much $$$$$ in that picture?
John Katok The project or the cranes? The project in 1983 cost about $700mm so that would be about $3.5 billion in todays dollars. If you meant the cost of the cranes, I don't really know, we had 24 down at that yard at the peak but the peak lasted several years, we mostly had 4100s, maybe eight 4600s, two 6000s and spare booms.Maybe $150mm. We only rented a few.
Harry Hedge That's a lot of rigs in one spot,
John Katok We split the tower into six box sections. The two that made up the very top ( left side) each weighed 2,400 tons. I wish i could post the photos of the 14 cranes, spaced only a few feet apart in some cases, making those 2,400 ton lifts. A box lift is more complex since when you reach the tip over point its likely to accelerate away, so we had 3 catch cranes on the receiving side plus two hold back winches. The crane operators and supervision were awesome and landed those boxes right in their cradles every time.
Francis Letecia Reyna Pawelek Did you all ever see the quarter mile long BULLWINKLE offshore rig built in ingleside? Kiewitt and another company was involved in that job
I got some nice pictures I’ll have to post too I think.
John Katok Yes, 1,350’ water depth, 55,000 tons, and loaded out onto the 851 launch barge circa 1988-89. Laying on its side the base was over 420’ tall.
Francis Letecia Reyna Pawelek I still got some pictures left and a couple sections of the parts and had som big cranes made by pip who lived nearby too
Here’s a couple guys of gulf marines yard
Then I found what I presume to be platform construction photos in some other "crane" postings and moved them here.
A lot more than just two cranes on this lift. I believe the section they lifted was built to the right of the bottom section. Look at the tracks for the cranes. They not only lifted that section in unison, they are moving it over the bottom section in unison! The dirt in these erection yards gets real hard. Note that they don't need any mats.

This is serious pic you don't see this everyday this was several years ago its got the most cranes on one pic in all the world
Willie Cromwell 4000's and 4100's
Joe Leonard And just think - not one computer. An actual human had to string a tape and look at a load chart. And nobody on a cell phone. Must be magic.
David Beard Yes Joe, the generation coming up now couldn't handle this.
Mike Keilen I get the pick and travel, but why all the jibs? Where and when was this?
Ed Flores Don't know about this one but the ones I did were in McDermott's yard in Amelia Louisiana. All yard cranes were equipped with jibs no point in removing them. All picks were at 60% of chart.

Those who worked at the large oil fabrication jacket yards. Who's yard and Manitowocs would these have belonged to????????
Ben StalveyGroup Admin A few 4600 series 4 ringers in this shot
Ben StalveyGroup Admin A 6000 can also be seen in this shot with white jib
Steve Khail I shot this photo for Manitowoc. It's a Brown & Root fab yard near Port Aransas, TX.
