On March 30, 2023, the Submarine Pipeline Post-Trenching Project of Jidong Oil Field NP1-1D and Its Energy Saving & Low-carbon Demonstration Area Construction was successfully completed. 

From the early sea ice to the later sandy sea bed, from the Hydraulic Excavator SE-12000 to the Mobile Sand Suction Pump, with the support of barge TANYI 601, the PMT overcame various difficulties of hydrogeological conditions, and completed the trenching work according to the project requirements in sections and time segments.

Jan.29 to Feb.10, 0.5km post-trenching of NP4-2 directional drilling section was completed, Mar.26 to Mar.30, 1.6km post-trenching of NP1-3 pipe section was completed, totally completed 2.1km pipeline post-trenching work.
