Commissioning an offshore vessel’s
power systems
The challenge to the customer
The China National Offshore Oil
Corporation (CNOOC) undertook a joint venture with Texaco and BP to
develop the oil and gas reserves in the BoHai Bay, northeast of
China. As part of the project, a floating production, storage and
offloading vessel (FPSO), the BoHai Century, was commissioned from
the Dailan New Shipyard.
The commissioning procedure for the
FPSO required the provision of a substantial, high-voltage loadbank
package to test the BoHai Century’s power generation system to
internationally accepted DNV standards. A flexible loadbank package
was required to allow the turbine generators to be tested in
different combinations. In addition, accurate data-logging services
were required to document the system’s performance under all test
conditions.
Aggreko's solution
Aggreko supplied and operated a 10
MVA resistive loadbank package together with high-voltage
transformers and ancillary equipment to conduct the test at
10.5kV.
The benefits to the customer
The data-logging system provided
accurate load-test conditions and monitoring. Aggreko onsite
engineers conducted each test to the customer’s satisfaction. “We
were very impressed with Aggreko’s equipment and the cooperation of
their onsite engineer,” stated Mr. Yao DeBin, Deputy General
Project Manager.
