On March 5, living quarters of Weizhou 12-2 project were set in place successfully. It is the third thousand-ton module lifted by "Lanjing" on the day in addition to DSM and DES, which further proved that offshore installation efficiency of "Lanjing" exceeds the international level. Since then, the lifting of all large structure monomers has been completed, and the project officially entered the offshore connection and commissioning phase.
Weizhou 12-2 oilfield Phase II development project includes east and west blocks, totally 7 monomers (total lifting weight: about 8500 t).
The relevant units involved in the construction cooperated with each other, made careful preparation, strictly implemented the construction plan, effectively overcame the adverse effects of changeable sea conditions in March, and finished offshore lifting successively, ensuring the smooth implementation of the offshore construction of the project.
From successful lifting of Weizhou east and west blocks on March 2 to successful installation of drilling rig module, living quarters and other monomers on March 5, the lifting operations of Weizhou 12-2 project were completed within 4 days (original planned duration: 7 days), which created extremely favorable conditions for the project to enter into the offshore connection and commissioning phase in advance and ensured the realization of the most important milestone.
