The oil capacity of a boom deployed in U-shape in a current depends primarily on the densimetric Froude number, with a critical Froude number above which the boom holds no oil, and an increasing capacity below this value. In low currents, the oil capacity is limited by the oil running out of the mouth, or to the top of the U. The forces on such a boom without oil are similar to those on any flat plate, and fix the shape of the U. With a boom full of oil, the forces are nearly independent of current velocity. The change in depth of the resultant force, as the boom fills with oil, requires adequate stability.
