We came into an anchorage recently and had to go around a large salvage operation. After getting ourselves settled we watch the operation and listened in to the conversation on channel 6.
So a little challenge for you all. When they got the object out of the water we saw that it was the extended boom of a crane which looked like it had snapped off and gone into the water.
They got it out of the water surface but they realized that they did not have enough "head room" (meaning wire left at the top of their salvage crane to get the item high enough out of the water to get it onto the barge). They needed to get their wire attached lower onto the salvaged item to lift it higher.
So they moved from where they were (in a couple of hundred feet) into shallower water - 31 feet. They then put the retrieved boom back down vertically so that the top of it (the black extended boom) was sticking straight out of the water. (I didn't get a photo of that stage). They then were able to just take the lift wire off, take it over to the barge to rework some part of it, and then replace it further down the retrieved boom to give themselves the headroom that they needed.
Here is the question: They had the retrieved boom just sitting there vertically, and they took the wire off, then just reattached it lower down. HOW DID THEY GET THE RETRIEVED BOOM TO JUST SIT STRAIGHT UP, STICKING OUT OF THE WATER, WHILE THEY WORKED ON IT - THERE WAS NO OTHER WIRES, ROPES OR SUPPORT. WHY DIDN'T IT FALL OVER?
I will post the answer later.
