Abstract
Gravity-based foundations are an attractive solution for certain offshore sites due to various environment-friendly reasons: no-piling, low energy installation through float-sink, less noise installation, use of low-carbon concrete, and increased use of local content. These types of foundations have been used in the past for supporting oil and gas installations. This chapter provides a simplified design approach for foundation sizing to assess financial viability at the preliminary stage. An example is provided to show the importance of steps in design.
