Abstract
A mooring attachment for substantially permanently connecting a buoy and a storage-process vessel, wherein the mooring attachment is of smaller weight but as great a level of reliability as prior art attachments. The attachment includes a mooring arm having opposite ends coupled respectively to the buoy and vessel in pivot joints that hold them a distance apart but without restraining the vessel against yaw movement, and a pair of stop devices on either side of the mooring arm for preventing extreme yawing of the vessel. The stop devices can be formed by a pair of chains, each chain extending from an opposite side of the vessel to the buoy end of the arm, and each chain extending in a loose catenary when the vessel is in a center position but being pulled tight when the vessel yaws by a predetermined angle which is more than 10.degree., to prevent jackknifing of the vessel.
