VESSEL MOTION CONTROL THROUGH ANCHOR-LINE DESIGN

Discussed are the catenary anchor lines used to anchor floating work vessels. The analysis developed suggests that vessel motion can be controlled by changing the pretension in the anchoring system, by changing the weight of the anchor lines (through use of wire line or chain), and by using a compound anchor line consisting of a wire-line section and a chain section. Calculations suggest that the use of chain anchor lines results in less surge than use of wire lines and that inappropriate design of an anchor line consisting of wire and chain can lead to very large surge motions.
