Stabilisation at rest: Anti-roll tank

[piratos]

Does anyone know why this idea never caught on? Seems so simple, no running costs, possibly no maintenance costs.

Is it because it just doesn't work? Or because it can't be hidden and looks ugly? Or another reason?

A valve to control the flow from one side to the other is a neat idea.

Possibly slightly off topic. I did a stint on a deep water dredger doing marine diamond exploration off the west coast of Africa. The vessel had a huge A frame and moon pool affair for the dredging tool, the A frame significantly above the CoG.. The vessel RV Benguela was a modified DP ferry with a shallow draft. During one particularly bad storm I was rather alarmed by the manner of the ship's roll. It would roll to ~18 degrees and hang there for a few seconds then roll back gaining momentum right the way through before just hanging there for what seemed forever. No even swing effect at all. Just a rush from side to side hang, rush back. Even the Fillipino crew looked rather anxious.

Doing any kind of construction work from a floating barge is hairy

Provided you can get on it in the first place.
