·
OSTI ID:5170599
A mooring system for a drill ship is described that has an annular cell mounted in the bottom of the hull concentrically around the moon pool. A plurality of annular cable drums are rotatable within the cell, the drums and the cell being rotatable about a common vertical axis. Anchor cables wound on the respective drums are directed by sheaves through the bottom of the cell through an opening in the bottom of the hull to anchors on the ocean floor for anchoring the vessel over a drill site. The drums are individually driven to adjust the associated cable, while the entire cell together with the drums is rotated within the hull to change the heading of the vessel relative to the anchors.
