The emplacement and recovery of large deep ocean cable systems containing in-line packages require a knowledge of the dynamic tension and motions of the system under the influence of surface ship motions, subsurface ocean currents and other external loads. A two-dimensional lumped mass model was developed to simulate simply connected cables and in-line packages. Cable tensions and mass point position and velocity are determined by a finite difference method using a predictor - corrector technique. The resulting computer program is applicable to single payload lowering, cable laying, deep sea mooring and deployment of large undersea cable structure.
