NUMERICAL ANALYSIS OF A NOVEL METHOD FOR SUBSEA EQUIPMENT INSTALLATION

摘要

This paper and the companion paper OMAE2010-49946 (de Mello et al., 2011) present the experimental and numerical results of the analyses of a novel method for subsea equipment installation. The conventional procedure, which is usually used, may lead to dynamic amplifications, depending on the launching cable stiffness and length. In the proposed method the equipment is lowered using two tug boats in a Y configuration. Trough the control of their relative position and also of the cable length it is possible to diminish the tension amplification.
