Document Type and Number:
WIPO Patent Application WO/2017/215052
Kind Code:
A1
Abstract:
An articulated column tower-type mooring device, comprising a base (40), a connecting arm mechanism (50) located underwater, a bow buoy mechanism (20), and a stern buoy mechanism (30). The lower part of the base (40) is fixed to seabed; the connecting arm mechanism (50) comprises a connecting arm (51) and a counterweight (55) fixed to the connecting arm (51); a bow end (512) of the connecting arm (51) is rotatably connected to the base (40), and a stern end (514) thereof is one end of the connecting arm (51) distant from the base (40); the bow buoy mechanism (20) comprises an upright rigid tower (21) as well as a buoyancy tank (22) and a ballast tank (23) that are both connected onto the upright rigid tower (21); the lower end of the upright rigid tower (21) is rotatably connected to the base (40), the buoyancy tank (22) is located above the ballast tank (23), and the upper part of the upright rigid tower (21) is provided with at least one bow cable (11) connected with the bow (102) of a mooring vessel (10); the stern buoy mechanism (30) comprises a stern buoy (32) located above the connecting arm (51) and an anchor chain (34) that connects the stern buoy (32) with the counterweight (55); the stern buoy (32) is provided with at least one stern cable (12) connected with the stern (104) of the mooring vessel (10). The device is low in costs, can avoid collision between a vessel and the buoys, and can effectively mitigate the issue of part fatigue.
