Design considerations for a deepwater pile-founded buoyant platform

OSTI ID:5423117
The paper presents a new compliant platform concept for deepwater drilling and production. Like an articulated column it derives its stiffness from the large buoyancy provided near the sea surface, but it does not use any mechanical articulation. Instead, the rotational compliancy is achieved here by an ingenious design of the pile foundation system, similar to the one adopted in the Lena Guyed Tower. The principles underlying the design of the various components of this structure are discussed, using as an illustration a structure with a total deck load of 30,000 Tonnes for a 350m water depth northern North Sea field.
