Abstract
An anchor system for a structure which experiences periodic buoyancy situations. The anchor system has a member connected at one end to a foundation and the other end to the buoyant structure. The member restricts movement of the buoyant structure in the transverse and longitudinal directions. The system allows the buoyant structure to move vertically between an upper and lower limit.
