Static analysis of marine cables via shooting-optimization technique

Abstract

Previous studies by De Zoysa and Chucheepsakul on a three-dimensional static analysis of marine cables yielded contradictory results for an example problem. This work addresses this discrepancy and furnishes the correct expressions for the set of differential equations governing the cable problem. The so-called shooting-optimization method is proposed as a solution technique. De Zoysa's cable problem was resolved, and presented herein are the correct variations of the tension components at the bottom end of the cable with respect to different angles between the ocean current direction and the projection of the ship-to-buggy line onto the horizontal plane.
