Abstract
A mooring terminal for deep water mooring is provided having a mooring head to which ships can be attached while either receiving or unloading liquid products. The mooring head is constructed so that it can accommodate all motions of the ship and includes a pair of yoke arms carrying hoses external from the mooring head to the ship. The yoke arms are attached to the mooring head in a manner to be able to pivot about a horizontal axis. The mooring head is supported above a deck which can rotate about a vertical axis in a manner to be rotatable about an axis orthogonal to the axis about which the yoke arms rotate. A pipe extends through the tower and at the top is coupled to the hoses by means which are pivotable about the same axes as the mooring head.
Claims7
A system for mooring a ship to the top of a rigid column which is attached to and supported on the ocean floor and through which pipes extend to be connected to pipes on a ship moored thereto comprising
- a pair of yoke arms extending from the top of said column to a ship to be moored,
- mooring means connected between said pair of yoke arms and the top of said column including means at the top of said column for affording accommodation to the motion of a ship moored to said yoke arms about at least three orthogonal axes of rotation, and
- pipe means coupling the pipes extending through said column to said pipes on said ship, said pipe means including
- means for affording accommodation to the motion of said ship about the same three orthogonal axes of rotation as said mooring means.
A system for mooring a ship through the top of a tower extending to the bottom of the ocean comprising
- a deck,
- means for supporting said deck on the top of said tower for rotation about an axis extending through said tower,
- a first and second pedestal means positioned at opposite ends of a diagonal of said deck and attached to said deck, said first and second pedestal means extending upwardly away from said deck,
- a transfer box positioned between said first and second pedestal means,
- first bearing means for rotatably supporting said transfer box means from said oppositely positioned pedestal means about an axis which is orthogonal to the axis extending through said tower,
- a pair of mooring yoke arms extending from opposite sides of said transfer box means towards a ship to be moored, and
- a pair of second bearing means for pivotably attaching said mooring yoke arms to said transfer box for affording rotation of said yoke arms about an axis which is orthogonal to the axis of rotation of said transfer box provided by said first bearing means.
A system for mooring a ship to the top of a mooring column through which pipes extend for coupling to a ship comprising
- deck means,
- first bearing means for supporting said deck means on top of said column for rotation about a longitudinal axis extending through said column,
- mooring means supported on said deck means for providing accommodation to the motion of a ship moored thereto,
- first pipe means extending from said mooring means to a ship,
- means for coupling said first pipe means extending to said ship to the pipes extending through said mooring column including
- a transfer pipe means for each first pipe means,
- means for coupling each transfer pipe means at one end to a different first pipe means for affording rotation therebetween about an axis which is orthogonal to an axis extending through said column,
- a coupling pipe means for each transfer pipe means,
- means for coupling the other end of each transfer pipe means to one end of a different coupling pipe means for affording rotation therebetween about an axis which is orthogonal to the axis of rotation between said first pipe means and said transfer pipe means,
- product swivel means supported on top of said column and extending through said deck means, and affording rotation to pipes coupled thereto about an axis extending through said column, and
- means coupling the other end of each coupling pipe means to said product swivel means.
