STORAGE TANK FOR OFFSHORE STORAGE OF LIQUID AND METHOD OF CONSTRUCTING AND INSTALLING SAME

摘要

A storage tank for offshore storage of liquid such as oil and the like and the method of constructing and installing same, wherein the storage tank has a side wall with the shape of a frustum of a hollow right circular cone and an enlarged diameter base or lower end and a reduced diameter top or upper end having a roof thereon, the frusto-conical configuration of the side wall of the tank substantially reducing the forces acting on the tank from a surrounding body of water or from wind or the like, and further resulting in a low center of gravity of the tank and a large water plane area so that the tank is inherently stable for towing in a body of water.
