China's largest land electricity application project, the Bozhong-Kenli oil field under China National Offshore Oil Corporation (CNOOC), on Monday completed the power transmission to three offshore platforms, a key milestone toward the oil field entering operation, CCTV reported.
According to the CNOOC, the project will be executed by transmitting 220 kilovolts alternating current to substations on three offshore platforms from a land substation under the National Grid, and transformed to 35 kilovolts alternating current for industrial and residential use.
With a total weight of 13,400 tons, the three platforms finished construction on October 25, China News Agency reported. Each platform has four-floor deck and a helicopter pad. The area of the largest platform is equivalent to nearly seven basketball courts.
The transmission of the land electricity to offshore platforms will rectify the energy structure of the oil field, and further accelerate the progress toward achieving carbon emissions goals.
After entering operation, it is estimated that the project will reduce 1.5 billion cubic meters of natural gas consumption annually during peak production years, equal to 650,000 tons of coal and reducing one million tons CO2 emissions, CNOOC said.
