ABSTRACT:
A motion compensating tank which includes a bottom tank portion which is able of holding liquid and a top portion which has a flotation collar and a flexible collar. The flotation collar is buoyant in the liquid so as to float substantially level thereon, and the flexible collar sealably joins the flotation collar to the bottom tank portion. With this arrangement liquid which sloshes in the tank can be retained without any substantial spilling over the top of the tank.
