This year, the “Key Technologies for Safety Evaluation of In-serviced Oil Derrick and Offshore Structural Equipment”, led by Northeast Petroleum University and its SANYA Offshore Oil & Gas Research Institute, won cippe Gold Innovation Award.

 

Due to the frequent disassembly and transportation of onshore derricks, the perennial high salt marine corrosive environment of offshore derricks and structural equipment, the dynamic load of drilling operations, overload, hurricanes and waves in the marine environment and other factors, derricks and offshore structural equipment are prone to deformation, fatigue, cracks, corrosion and other damages during service, resulting in a significant reduction in the bearing capacity and durability of derricks and offshore structural equipment, which seriously affects the safety of onshore and offshore oil and gas drilling development and production. “Key Technologies for Safety Evaluation of In-serviced Oil Derrick and Offshore Structural Equipment”, through the bearing test of physical prototype / indoor model / digital model, macro (deformation) and micro (crack) damage detection, digital twin model simulation test, the scientific and objective evaluation of the safe bearing of derrick and offshore structural equipment is given according to the theoretical criterion of strength stability, and the repair suggestions for various damages of derrick and offshore structural equipment are put forward at the same time. This technology has been proved to be scientific and feasible by a large number of practical verification and promotion. This technology innovates the physical model and test device, damage identification and detection technology, structural performance testing technology, digital twinning and safety evaluation technology, and provides a guarantee for the safe production of land and marine oil and gas resources exploration and development.

 

This technology has accumulatively authorized 6 patents, formulated and revised 3 standard specifications, and published 30 papers.

From 2016 to 2021, Northeast Petroleum University and SANYA Offshore Oil & Gas Research Institute have detected 446 derricks of various types, among which, 330 derricks in service have been put forward with opinions on degradation, 5 derricks in service have been put forward with opinions on scrapping and written off in time, which eliminated potential safety hazards. In terms of other offshore detection, the project team has completed the detection of 1 offshore drilling rig substructure, 23 offshore cranes, 3 offshore platform and 2 land terminal pipelines of CNOOC, which provides a reliable guarantee for the safe production of onshore and offshore oil and gas resources exploration and development, and provides theoretical basis and technical services for the safe production of oil fields.
