In collaboration with the CNOOC Ltd. (Shenzhen),we have participated in the scientific research project of “Key Technology Research of Design, Construction and Application For Triangular Multifunctional TLP” approved by the Ministry of Science and Technology. We presided over the sub-project of “Design and Research of Main Bearing System for Single-Deck Rotary Slip Rig Substructure”. Here are the main achievements of this research and development project:

1) Complete the conceptual design of rig substructure and main bearing system structure;

2) Complete the basic design of rig substructure and main bearing system structure and simulation design;

3) Complete the basic design of modular drilling rig system.
