Yokogawa Signs Sole Source Agreement with
Shell Exploration & Production for Monitoring and Control Systems
- For greenfield and facility improvement projects to be executed in the Gulf of Mexico -

Yokogawa Electric Corporation announces that Yokogawa Corporation of America, a North American subsidiary, has concluded a sole source agreement with Shell Exploration & Production Company, USA (Shell E&P) of the Shell Group. Over the five-year contract term, Yokogawa will be the sole provider to Shell E&P of monitoring and control systems to be used in their facilities in the Gulf of Mexico, North America.

Under the terms of the contract, Yokogawa will deliver CENTUM™ CS 3000 monitoring and control systems as well as ProSafe-RS™ safety instrumented systems for facility improvement projects. These projects involve crude oil and natural gas production facilities located in the Gulf of Mexico.

As part of these projects, Shell E&P will be upgrading the existing monitoring & control, safety shutdown, and fire & gas systems of several existing production facilities in the Gulf of Mexico. Also planned is the construction of Ursa Water-Flood facilities and the Perdido Regional Development Host to develop the Great White, Tobago and Silvertip Fields located in Alaminos Canyon, offshore Gulf of Mexico. Moored in about 8,000 feet of water, the regional direct vertical access spar capable of handling 130,000 boe (= barrels of oil equivalent) per day will be the deepest spar production facility in the world.

For these facilities, Yokogawa will deliver the CENTUM CS 3000 R3 Integrated Production Control System and the ProSafe-RS Safety Shutdown and Fire & Gas Detection System.

"Yokogawa is extremely honored to receive this contract from Shell," said David Johnson, President and CEO of Yokogawa Corporation of America. "It will involve Yokogawa in all aspects of the projects from application engineering to systems integration. We consider this a very positive next step in strengthening our long-term relationship with Shell. The work in the Gulf of Mexico will be some of the largest and most complex projects we have done with them and bring into play some ground-breaking technologies."

Yokogawa has been awarded this important contract as a result of the Shell Group's very positive evaluation of the company's delivery of more than 200 systems during the past 20 plus years, as well as its proven project execution capabilities, cost competitiveness and Customer Centric Solutions approach. In April 2005, Yokogawa also signed a strategic supplier contract with the Shell Group, under which it provides Shell with products, engineering, and maintenance services.
