= Embedded Anchors for Offshore Structures = Embedded anchors are anchors that derive their capacity from the frictional and/or bearing resistance of the soil surrounding them. This is converse to gravity anchors that derive their capacity from their weight. As offshore developments move into deeper waters these gravity based structures become more costly and difficult to transport. This proves opportune for the employment of embedded anchors.

There are multiple types of embedded anchors that may be adopted to moor offshore oil and gas or renewable energy facilities. Often constructed using steel and/or concrete, these anchors may be adopted for either short-term or long-term applications. Examples of facilities that may need mooring are FPSOs (floating production storage offloading units), mobile offshore drilling units, offshore production platforms, renewable wave energy convertors, floating liquefied natural gas facilities etc. The figure below outlines selected deep water embedded anchors available to moor offshore floating structures.

Each of these anchors presents their own set of advantages for anchoring offshore structures. The choice of anchoring solution depends on multiple factors some of which are the type of offshore facility that requires mooring, the location of the development, economic viability, the lifetime of its use, soil conditions present and resources available.
