Anchor-last deployment procedure for mooring

Creator:: Thresher, Robert W. and Nath, John H.
Abstract:: The anchor-last mooring procedure is investigated in order to determine the transient forces in the mooring line and the velocities of the anchor. Transient forces were determined and the results showed that no severe snap loads occurred for the cases investigated. In addition, it was found that the vertical velocity...
