Seafastening apparatus for a tensioner assembly

Abstract

A seafastening apparatus includes a movable frame having an opening configured for receiving and at least partially supporting an equipment unit. A locking device is configured for selective locking and releasing of the equipment unit and hence controlling lateral movements of the equipment unit relative to the apparatus. The locking device includes wires configured for connection to the equipment unit and tensioners configured for controlling the tension in each wire, and a pair of extendible and retractable arms are configured for conveying and guiding at least on of the wires.
