Abstract: Dimensional control is one of the important parts in process of jacket construction on land. There are different dimensional control methods depending on the construction technology. The jackets located in shallow waters usually are constructed by vertical process. As a summary of dimensional control experience of vertically constructed jackets in recent years, this paper introduces the dimensional control methods used at the stages of tubular splicing, frame prefabricating and field assembling. The dimensional control key points, common mistakes and solutions at each stage of jacket construction are also illustrated. Moreover, a new dimensional control method of jacket construction at field assembling stage is proposed.
