Abstract
Abstract A system for mooring a ship or like floating vessel, in particular, an oil-tanker, to an off-shore column, and for transferring a fluid cargo such as gas, petroleum oil or the like, by means of at least one articulated arm carried by the vessel, wherein the improvement consists in that the arm supports at its upper end a connector device capable of being fixedly placed on a mouth-piece, provided on the head of the column, and that mooring apparatus is provided to allow the vessel, once the connector device is thus placed, to be moored through the device and to move around the latter so as to be placed in the wind's eye.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
193 words
A system for mooring a ship or like floating vessel, in particular, an oil tanker, to an off-shore column, and for transferring a fluid cargo such as gas, petroleum oil or the like, by means of at least one articulated arm carried by said vessel, said arm supporting at its upper end a connector device capable of being fixedly placed on a mouth-piece provided on the head of said column, and mooring means for allowing said vessel, once the connector device is fixedly placed, to be moored through said device and to move around the latter so as to be placed in the wind's eye, said connector device comprising a hollow body forming a centering and guiding cone, adapted to be fitted onto a mouth-piece head extending from a conduit provided on said column, a sliding connector element operable to be inserted into the inlet of said mouth-piece in connecting relationship in conjunction with sealing means, locking means for maintaining the connecting condition of said connector device and said mouth-piece, and means for ensuring, once the connection is completed, the free rotation of said mooring means connecting said connector device to said vessel.
Claim 2
Independent Claim
193 words
A system for mooring a ship or like floating vessel, in particular, an oil tanker, to an off-shore column, and for transferring a fluid cargo such as gas, petroleum oil or the like, by means of at least one articulated arm carried by said vessel, said arm supporting at its upper end a connector device capable of being fixedly placed on a mouth-piece provided on the head of said column, and mooring means for allowing said vessel, once the connector device is fixedly placed, to be moored through said device and to move around the latter so as to be placed in the wind's eye, said connector device comprising a hollow body forming a centering and guiding cone, adapted to be fitted onto a mouth-piece head extending from a conduit provided on said column, a sliding connector element operable to be inserted into the inlet of said mouth-piece in connecting relationship in conjunction with sealing means, locking means for maintaining the connecting condition of said connector device and said mouth-piece, and means for ensuring, once the connection is completed, the free rotation of said mooring means connecting said connector device to said vessel.
Claim 3
Dependent Claim
34 words
A system according to claim 1, comprising a hawser, wherein the hawser end which is adjacent to the tower is attached to a ring freely movable on said hollow body of said connector device.
Claim 4
Dependent Claim
31 words
A system according to claim 1, wherein said mooring is ensured only by said arm and said arm carrying said connector device is connected to the latter through a rotatable joint.
Claim 5
Independent Claim
207 words
A system for mooring a ship or like floating vessel, in particular, an oil tanker, to an off-shore column, and for transferring a fluid cargo such as gas, petroleum oil or the like, by means of an arm comprising at least two articulated arm portions carried by said vessel through a turret-like swivelling head the base of which is secured to said vessel, said arm supporting at its upper free end a connector device capable of being fixedly placed on a mouth-piece provided on the head of said column, and mooring means for allowing said vessel, once the connector device is fixedly placed, to be moored through said device and to move around the latter so as to be placed in the wind's eye, said connector device comprising a hollow body forming a centering and guiding cone, adapted to be fitted onto said mouth-piece provided on said column, a sliding connector element operable to be inserted into the inlet of said mouth-piece in connecting relationship in conjunction with sealing means, locking means for maintaining the connecting condition of said connector device and said mouth-piece, and means for ensuring, once the connection is completed, the free rotation of said mooring means connecting said connector device to said vessel.
Claim 6
Independent Claim
207 words
A system for mooring a ship or like floating vessel, in particular, an oil tanker, to an off-shore column, and for transferring a fluid cargo such as gas, petroleum oil or the like, by means of an arm comprising at least two articulated arm portions carried by said vessel through a turret-like swivelling head the base of which is secured to said vessel, said arm supporting at its upper free end a connector device capable of being fixedly placed on a mouth-piece provided on the head of said column, and mooring means for allowing said vessel, once the connector device is fixedly placed, to be moored through said device and to move around the latter so as to be placed in the wind's eye, said connector device comprising a hollow body forming a centering and guiding cone, adapted to be fitted onto said mouth-piece provided on said column, a sliding connector element operable to be inserted into the inlet of said mouth-piece in connecting relationship in conjunction with sealing means, locking means for maintaining the connecting condition of said connector device and said mouth-piece, and means for ensuring, once the connection is completed, the free rotation of said mooring means connecting said connector device to said vessel.
Claim 7
Dependent Claim
30 words
A system according to claim 4, wherein means are provided to allow, after the connection, for certain resilient displacements of the said turret-like swivelling head to withstand the mooring strain.
Claim 8
Dependent Claim
68 words
A system according to claim 4, wherein one of said arms is carried by said turret-like swivelling head, whereas the other is pivotally connected to the first one and movably connected through a universal joint to said connector device, in combination with means for opposing a damping effect to the relative rotation of both arms with respect to one another and for opposing the effects of sea heave.
Claim 9
Dependent Claim
22 words
A system according to claim 6, wherein said damping means comprise pneumatic-type tensioning means combined with an actuator for operating said arms.
