Discussion on paper B7.1 (Brook-Hart)

Did you look at making the core structure self buoyant for float unit, as opposed to building vessel? And if yes, what were the findings?

Author's reply -

The design team did initially look at making the gravity base foundation ("GBF") self-floating. However we found that the shape needed for efficient transfer of forces down the stem to the baseplate gave a poor shape from the naval architect's point of view for stability during a tow to site. Therefore, to avoid compromising both the design of the GBF for its service life, and the stability during towing, the GBF's own buoyancy is supplemented by the purpose-designed transport and installation barge ("TIB") which is designed to optimise the transport and installation process.
