- Abstract
- Ocean developments gradually move to deep-sea in the 21 century. A deep-sea unmanned underwater vehicle (UUV) is one of important tools for ocean resource survey. A marine cable plays an important role for the safe operation and signal transmission of a deep-sea UUV. The umbilical cable of a deep-sea UUV is excited by surface vessel motion and shows nonlinear dynamic behaviors. In this study, a numerical program is applied to a 6,000m long cable for a deep-sea UUV to show the dynamic behavior of the umbilical cable and ROV launcher under heave and combine excitations Copyright ？2005 by The International Society of Offshore and Polar Engineers.
