Research progress on decommission schemes and technical methods for offshore jacket platforms
Due to its advantages of strong adaptability and high safety,the jacket platform has been widely used in offshore oil and gas development.As more and more jacket platforms will reach or exceed the design life,the platform decommissioning has become one of the important problems in the field of offshore oil and gas development.This paper systematically introduces domestic and international regulations on jacket platform decommissioning,focuses on the decommissioning constraints,application fields,similarities and differences between different international conventions,and summarizes the key points of regulations and requirements on jacket platform decommissioning among China,the United Kingdom,Norway and the United States,and analyzes four typical decommissioning projects worldwide.In view of this,the different decommissioning schemes,and scope of application of jacket platform are summarized and analyzed,as well as the operational difficulties and implementation details of the three key process technologies of dismantling,cutting and transportation during decommissioning.The review can provide a theoretical basis for optimizing the decommissioning plan and key technical methods of the offshore jacket platforms,and has important engineering significance for marine environmental protection,navigation and fishery production.
