GMC & Horton Wison Deepwater confirm Joint Venture for ground breaking Shallow Water Buoyant Tower Design and Supply – First contract secured and underway

GMC and Horton Wison Deepwater today 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.”

First Project  

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.

The CX-15 shallow water tower is well on track for a Q3 2012 installation and will be the first application of this design.  The platform is designed for 12, 200 barrels of oil per day, gas compression capacity of 12.8 million standard cubic feet per day and produced water handling and injection capacity of 3, 500 barrels per day. A total of 24 drill slots will be available, some of which will be used for gas and water reinjection wells. The CX-15 platform will be located about one mile from the existing CX-11 Corvina platform, with both platforms interconnected via a series of subsea pipelines.

The JV completed the FEED scope in 2011 which led to detailed design for the buoyant tower.  Fabrication is underway at Wison Offshore and Marine’s yard in Nantong, China. GMC are also providing project management and installation services for the CX-15 platform.

Jim Maher COO of the JV commented “We are pleased to be working with BPZ Energy on this important project which draws upon deepwater technology and applies it in the shallow water arena.”
