Abstract

A concrete barge (30) having concrete-coated oil storage tanks (33) secured to its deck is sunk to the sea bottom (B) at an oil production site. Oil from an adjacent caisson-supported facility (12, 13) is temporarily stored in the tanks. Compartments (32) in the barge (30) are filled with water for ballast and trim as the barge (30) is towed to the site. The compartments (32) are flooded with seawater to sink and hold the barge (30) on the sea bottom (B). Descent of the barge (30) is regulated by controlling the placement of and air pressure in the tanks (33). The barge (30) and tanks (33) are subsequently filled with seawater. Oil is introduced into the tanks (33) from the production facility (12, 13) in a manner which displaces an equal volume of seawater. Oil is discharged from the top of the tanks (33) to sales lines (22) by introducing seawater into the tank bottoms.
