In the morning of Nov. 11, as the 2nd part of top derrick successfully butt connecting with the 1st part, the in-dock erection of derrick for H1318, the JU-2000E Jack-up Unit for CPOE was completed. Up to now, this Jack-up Drilling Rig has shown up her whole body in front of us. In SWS offshore history, this is the first time that the company realized in-dock lifting of derrick by 600-ton gantry crane. Comparing with lifting of derrick by floating crane for "HAI YANG SHI YOU 981", which is the deepwater semi-submersible drilling rig, H1288--the first built Jack-up in outfitting quay area, the in-dock lifting is safer and lower down the cost. It is also significant for building cost and risk control management during the construction of the offshore engineering. To guarantee the integration of this crucial milestone, before the erection, the Offshore Engineering Project Dept. made the careful deployment and actively organized special subject meetings for many times with Design Dept., Erection Dept., Hull Outfitting and Installation Dept., and other relevant departments to reconsider the erection plan, hash out the difficulties, evaluate the risks and fully implemented the plan in the details. During the lifting of Derrick for H1318, all the departments carried forward their conscientious work style. Particularly, the erection dept. had completed the lifting support job by all kinds of gantry cranes, turning around of derrick and butt connection job so well. As well as the Hull Outfitting and Installation Dept. orderly coordinated the erection and appropriate preparation, and efficiently completed the butt connection of derrick. The successfully completion of derrick lifting indicates including of cantilever beam and turret, all the key large structure blocks have been lifted in drydock by gantry crane. And the tasks of all the large scale of equipment lifting milestones were smoothly completed. That has established a solid foundation for integrity before launching, completion of drilling system and commissioning of follow-up systems.
