Wison Offshore & Marine Announces Award for the Construction of One Modular Drilling Rig for the Gulf of Mexico

Shanghai, China – 10 July, 2013 – Wison Offshore & Marine Ltd. (Wison), a subsidiary of the Wison Group, announced today the award of a contract from China Oilfield Services Limited (COSL) to supply one modular drilling rig for use on a platform in the Mexican sector of the Gulf of Mexico operated by Petróleos Mexicanos (PEMEX).

Under the contract, Wison will perform the project management, procurement, production engineering, fabrication, load out, offshore installation and commissioning support of one 3000hp modular drilling rig that will be installed on the Tsimin-C drilling and production platform in the Mexican Bay of Campeche. The drilling facility is based on an innovative self-installing design which will consist of some 97 smaller units that will require significant integration work to strict tolerances during module construction. Wison will fabricate the approximately 2500-ton module at its Nantong facility in China with the delivery planned for the second quarter of 2014.

The project marks Wison’s second contract from COSL for the delivery of modular drilling units to PEMEX. In 2007, Wison delivered modules for four platform rigs that are currently operating offshore Mexico. Wison also delivered two modular platform rigs to COSL in 2010 for operation on CNOOC facilities offshore China.

“Wison has established a strong track-record in delivering drilling modules for COSL and we are extremely pleased to expand this relationship and provide more high-quality facilities for PEMEX,” said Wison Offshore & Marine Executive Vice President, Dr. L. Dwayne Breaux.
