  • Topsides engineering best practices for lightweight design

    Kent McAllister and Hickman Brown

    The design of any offshore structure is no easy task. There are numerous influential drivers that can dictate its layout and payload. New concepts, unique materials of construction and deepwater experience have led to continued discussion of best practices in topsides design. An overriding factor in any deepwater project, however, is cost. And, since the weight of both the structure and the topsides production facility directly impacts cost, it must be a top priority for design considerations. Our experience has shown that a topsides installed cost ranges from $35,000–50,000/ton. By reducing the weight of a 20,000-ton topsides by 15%, it is possible to slash capital costs of the project by $100-150 million—not a savings to be overlooked.
