ABSTRACT OF THE INVENTION A method of laying pipeline in water greater than 1000 feet deep is disclosed whereby the pipeline is assembled on board a lay barge and then, during deployment, is bent beyond typical elastic bending limitations and Conventional Lay bending strain limitations while passing along a stinger where it is subsequently reverse bent to remove any permanent curvature. Upon further deployment, a generally horizontal axial load is maintained on the pipeline as it comes to rest upon the sea floor such that the final in-situ residual bending curvature of the pipeline is nearly zero or falls within an acceptable range.
