Successfully upgraded Cnooc Zhanjiang Weizhou 12-1 F&G system from previous version of "EQ" to current "EQP" F&G detection and Releasing System, which has greater functionalities and faster processing power. All existing detectors and inputs/outputs modules of the older "EQ" architector could be employed in the current "EQP" system, making it the ONLY TRUE back-ward compatible F&G system in the world.
