Paper presented at the The Eleventh ISOPE Pacific/Asia Offshore Mechanics Symposium, October 12–14, 2014
Paper Number: ISOPE-P-14-083
... Abstract In this paper, we proposed a three-dimensional model for the tension analysis of submarine power cables during laying operations. Both flexural rigidity and axial elasticity were taken into consideration in the form of classical Euler-Bernoulli beam element theory. The governing...
