I have heard....(only as a comment someone said in passing)
That some ships have computer controlled ballast, as the crane swings,
ballast is being pumped around in various tanks to compensate.
And when that system fails.....
Some drilling rigs (probably most) have a small "Straw line" my neighbor called it. IIRC on his 22-w it was 3/8" cablestorm.
And a crane question - there's a "main hook" (presumably the one rated for 3Kt), and a second hook, which I take it is for help handling long objects, flipping things over, and so forth.
But why would there be 3?

Picking up tongs, bringing in a piece of casing, etc.
In the case of this big crane, also for handling the large slings.
