On December 27, 2017, the diving and mooring teams of the company, together with Warwick and other professional forces, overcame many difficulties under bad sea conditions and assisted in shutdown and overhaul. The fsou of "Nanhai Shengkai" in May was successfully connected to the single point mooring system, creating conditions for the smooth resumption of production of CNOOC Lufeng oilfield.

The underwater inspection, cleaning and recovery of the single point buoy is the key operation before the "Nanhai Shengkai" returned to the oilfield after maintenance. On December 11, the underwater engineering department took the command to set up an emergency team to start land preparation, so it worked overtime to submit a practical technical construction scheme, operation risk assessment, operation emergency plan, etc. to the owner, and quickly transferred elite generals Implement the diving bell and other operation equipment resources, and take the "Huaming ship" to sea on December 15 to seize the favorable operation time point.

Affected by the strong cold air, the northeast monsoon in the eastern sea area of the South China Sea is booming, and the on-site surge is basically more than 3.5m. During the on-site standby, the diving team closely observes the sea conditions with the owner's representative, repeatedly deduces the process and evaluates the risk in detail. On the one hand, there were no launching conditions under bad sea conditions, and on the other hand, CNOOC executives required the time point for the positioning of oil tankers and the resumption of oil field production. The on-site operators withstood the pressure and acted actively. Finally, they seized the only two operational windows and successfully completed the single point pontoon cable connection and other emergency operations on December 24.

However, in the next two or three days, the tanker connection operation under extreme sea conditions is also a race against the clock, repeated setbacks and repeated battles. At 17:41 on December 26, the company received the instruction of "dispatching an experienced mooring captain to go to sea on the morning of the 27th to participate in and assist in the on-site connection operation, and strive to complete the operation on the same day before the sea condition worsens further". At 15:53 on December 27, the good news "the anchor chain has entered the cabin and victory is in sight" came from the scene. At 16:20, the mooring captain Sun Gang informed "the oil tanker has been successfully in place and stopped for test" through high frequency.

Thanks to its excellent performance in the emergency response of "Nanhai Shengkai" in July 2017, the company once again demonstrated its excellent service skills in the implementation of the urgent, difficult and dangerous task of oil tanker connection, displayed its own strengths and alleviated the urgency of the owner. It is a reliable professional team with good performance.
