PRACTICAL CONSIDERATIONS IN PLACING UNDERWATER PIPELINES

The greatest risk in placing underwater pipelines is the danger of buckling and subsequent failure of the pipe. To prevent this, the pipeline structure design must consider: currents which impose lift and drag forces; bottom soil characteristics; allowable weather tolerances; equipment limitations; availability of shore support facilities; and other practical factors. The importance of a close working relationship between engineering and construction is stressed. The fundamentals of underwater pipeline design and various construction methods (lay barge, reel barge, pulley floating string, and pull barge) are discussed.
