Abstract
An offshore structure and method of constructing same are disclosed. The offshore structure comprises a jacket assembly, a bottom tank secured to the bottom of said jacket assembly and a movable tank which is vertically slidable along said jacket assembly and which can be positioned on said bottom tank as a ballasting and storage tank. The offshore structure further includes a guide mechanism between said jacket assembly and movable tank to guide the vertical sliding of said movable tank, a frictional plate disposed on the contact surface between said bottom tank and movable tank so as to permit the two tanks to slide relative to each other in a given horizontal movement, and a buffer disposed between said jacket assembly and movable tank.
