Summary: | After more than ten years' development, the functions of workover rigs in China can generally satisfy the demands of offshore oilfield production. For conventional workover rigs, large working space and guide rails are necessary, and they bring trouble to the workover operations. The high cost of manufacture, transportation, installation and running such general workover rigs is also an inevitable problem. Because of the advantages of the hydraulic energy-storing workover rigs, such as energy saving, environmental protection, small occupation and convenient installation, they have been widely used in onshore oilfields. In this paper, the preliminary structural design of a newly developed simple offshore workover rig will be introduced and the feasibility of applying this type of rig will be discussed. |
