System Analysis and 3D System Model for Scheme Design of Self-elevating Drilling Unit

In this research the design process and main content in each design stage of self-elevating drilling unit are analysed. According to the specific circumstances of scheme design of the self-elevating drilling unit, it is regarded as a large-scale system and treated with systems engineering theories and methods. The process in designing self-elevating drilling unit has been analyzed by the way of system analysis, in which the steps have been advanced. Besides,in accordance with the Hall's three dimensional structural model combined with the traits of scheme design in drilling unit, a three-dimensional structural model system in drilling unit is formed for guiding and realizing this scheme design. At last, the 300ft water depth self-elevating drilling unit scheme design for Liao He equation ltd. was implemented with this method, and feasibility of the model system is proved.
