Basic elements of the lay barge comprise five to eight work stations where a sequence of operations is carried out to assemble the line. Basic elements of the pipelaying system include the lay barge, the mooring system, the pipe tension devices, the stringer, and the suspended pipe span. The suspended pipe span is an "s" shaped curve of which the lower portion is the sag-bend region and the upper portion is the over-bend region. Control of bending strain in the sag-bend region by application of horizontal stress, described with graphs for 12.75 in. and 24 in. pipe (strain vs ft off bottom for several values of tension), can be used to advantage for even the largest pipeline.
