Load bank rental for commissioning an offshore vessel’s power systems

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 load bank 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.

Resistive load bank package

Aggreko supplied and operated a 10 MVA resistive load bank 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.
