Embodiment Construction

[0030] The present invention is described with reference to preferred embodiments. The following descriptions have reached the point of detailing specific embodiments or specific uses of the present invention, but these are only exemplary and should not be construed as limiting the scope of the present invention. On the contrary, it is intended to cover all changes, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.

[0031] As used herein and in the claims, the term "floating structure" means any structure that floats in a body of water. By floating structure is meant a structure that is capable of floating when in its final installed position, but such a structure is also capable of sinking in a body of water, for example by ballasting. Examples of floating structures include, but are not limited to, offshore floating structures, spars, conventional spars, deepwater caissons, truss spars, unit spars, tub...

Abstract

The invention retates to a method for installing a heave plate (100) on a floating structure (10). The method allows for construction of the floating structure (10) and heave plate (100) on-shore, while providing for installation of the heave plate on the floating structure at sea.

Description

technical field [0001] The present invention relates to a method for mounting a heave plate on a floating structure, such as a spar, and to a floating structure formed thereby. The method includes providing a heave plate and a floating structure at an offshore connection site and a process for connecting the heave plate to the floating structure. Background technique [0002] As the oil industry invests in the exploration for hydrocarbon resources in deep offshore areas, technologies must be developed to recover these hydrocarbons. More and more floating structures are being used in these deep sea applications as opposed to bottom-founded structures. One specific floating structure employed by the petroleum industry in deep sea operations is the spar or deep water caisson floating vessel (DDCV), which has a long vertically arranged floating hull or caisson that The operating position has an upper portion that supports the drilling and / or production platform above the water...
