Project: Lufeng Oilfields Regional Development Project

Time of completion: December 2022

Project introduction: This project located in the Pearl River Mouth Basin, consists of two drilling and production platforms and a subsea production system. The core facility of the project is Lufeng 15-1 jacket “Haiji-1”, which is 302 meters high and weighs 30,000 tons.

Project highlights: Deepwater jacket “Haiji-1” , the first 300m deepwater jacket in Asia, is designed to withstand extreme sea states with a return period of 100 years. COOEC has overcome many challenges associated with strong internal waves, highly consolidated soil in the continental slope zone, large sand waves and sand ridges, super-large structures in position and the stability of super-large X-braced structures. It has employed more than ten innovative technologies including but not limited to the overall design of deepwater jackets, the design and construction of stepped mud pads and independent launching trusses, the lifting of large-size, wide-span, heavy structures involving multiple cranes, and digital twin-based operation and maintenance, embracing all-round improvement in the areas of basic theory, structure type/form, design concept, material selection, construction technique, operation and maintenance.
