Abstract
Abstract A tension mooring device for vessels is inclusive of a marinesituated platform on which a pneumatic-hydraulic cylinder mechanism is mounted. Included in the mechanism is a piston reciprocable to define a variable volume in the cylinder which is augmented by a closed air reservoir. There is at least one sheave mounted on the platform over which a cable is reeved. The cable is connected to move with a rod on the piston for transference of forces therebetween. A shackle at one end of the cable is provided for the connection of a mooring line from a vessel. The arrangement is such that variable air pressure in the cylinder and reservoir maintains a tension on the cable and correspondingly on the mooring line to accommodate motion of a moored vessel without damage.

Claim 1
Independent Claim
191 words
A tension mooring device for use in mooring vessels to a marine platform, comprising: an upstanding cylinder mounted on said platform, a piston vertically slidable in said cylinder and defining upper and lower variable volume chambers in said cylinder, an upstanding closed air-oil reservoir adjacent said cylinder, a conduit communicating the lower portion of said reservoir to the lower chamber in said cylinder, a body of oil in the lower portion of said reservoir and extending through said conduit into said lower chamber, a body of air confined in said reservoir above said body of oil, means adjacent said cylinder defining a closed pressure chamber of lesser volume than said reservoir, conduit means connecting the upper portion of said pressure chamber to the upper portion of said upper cylinder chamber, a piston rod secured to said piston and extending upwardly out of said cylinder, a sheave journalled on said piston rod outside said cylinder, and a cable reeved on said sheave and having means for securing the same to a vessel, said cable being directed from said sheave so that tension in said cable urges said piston downwardly in said cylinder.
