Abstract
An analytical method is presented for finding the elastic deflection o f submerged pipelines laid with an articulated stinger in which the bu oyancy of each element is adjustable. The computer time required for t he method is much less than that for the finite element method, so tha t optimization of the laying parameters can be performed in a large re gion using mathematical programming. A practical example shows the eff iciency of the proposed method. Copyright (C) 1996 Elsevier Science Lt d
