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.
