GMC and Horton Wison Deepwater confirmed their Joint Venture established to design and supply innovative Buoyant Towers for shallow water fields. Kevin Chell CEO of the joint venture stated “The Buoyant Tower concept draws on the proven technology of the cellspar and the design provides multiple benefits for fields where other concepts would be problematic requiring high capital costs and expensive crane barges for installation. The buoyant tower can operate in water depths up to 700 feet and can be relocated allowing small marginal plays to be exploited in a cost effective manner. The design allows for hydrocarbon storage if needed, can eliminate separate shallow water drilling units and provides a high level of flexibility for the operator.”
The benefits of the design were recognized and adopted by BPZ Energy for their new platform at the Corvina field offshore Peru. The tower is composed of four cylindrical cells and is connected to the seabed by a single suction pile which is integral to the hull structure. The tower and decks with the production equipment will be transported from the fabrication yard to Corvina on a submersible heavy lift ship. After upending, fixed and variable ballast will be pumped into the hull to provide stability for the platform.
