CONCEPT/BASIC DESIGN

3DENT specializes in conceptual and basic design for the for the offshore oil & gas and wind energy industries. We provide structural, hydrodynamic and naval architecture services for shallow water solutions including fixed structures, liftboats, and jackups and a set of solutions for deep and ultra-deepwater including semisubmersibles and floating production installations. 3DENT also has expertise in the evaluation of novel concepts for production facilities and gas transport.

Wind Cell Spar

3DENT developed the Wind Cell Spar concept including the completion of all analyses and documentation to obtain an Approval-in-Principle from Lloyd’s Register. The Wind Cell Spar is based on the cell spar concept. The cell spar incorporates a series of smaller diameter cylindrical columns (referred to as “cells”) combined in a parallel formation to form a larger equivalent diameter hull similar to a traditional spar. The cell spar is an established design that has been successfully employed in the offshore oil and gas industry.

The design lends itself to domestic construction as it leverages the existing fabrication expertise of the United States by employing techniques that are closely aligned with jacket and suction pile construction. The steel plates of the Wind Cell Spar are welded and rolled into the diameter of the can sections. The can sections are then connected in an assembly line like process using a Cell Assembly Rack.
