As the deepwater jackets are normally taller than ordinary jackets, most of them are built in the way of lay-down construction. The single panel is an elementary unit of a jacket, composed of horizontal single panel or vertical single panel. This paper introduces a lifting method for different single panels of deepwater jacket, considering various factors such as primary standing position of cranes, the cranes route, cranes capability, level lift and turn-over lift, and other crucial elements in lifting process. Padeye lifting and sling hauling are two patterns in the lifting process, consisting of pipe padeyes and anti-slipping sling columns.
