Abstract: Fluid transferring apparatus, more commonly referred to as a marine loading arm, comprising rigid, pivotally-interconnected inboard and outboard arm members pivotally mounted on an upstanding riser, and a system for maintaining the outboard member in a substantially horizontal attitude during the fluid transfer process. A first hydraulic ram, connected between the riser and the inboard member, and a second hydraulic ram, connected between the inboard member and the outboard member, are functionally coupled to a hydraulic system with an outboard arm member attitude sensing means, so that if the outboard arm member pivots more than a pre-selected distance above a horizontal attitude the first hydraulic ram provides pressurized fluid to the second hydraulic ram to return the outboard member to its horizontal attitude.

Abstract: A system for sensing the positon in space of the outer end of an articulated fluid loading arm while it is connected to a marine tanker or other transport vessel, and for sounding an alarm if the arm's operating envelope is exceeded. The sensing system includes means for determining various angles representative of the orientation of the booms or limbs of the arm, and a microprocessor for using these angles to compute the spatial position of the arm's outboard end. The boundaries between the safe and unsafe areas of operation of the arm are stored in a digital memory and compared with the actual position of the arm. The boundaries which define the safe areas can be any desired shape, and the shape can be readily changed by storing a new set of boundary values in the digital memory. If desired, the location of the boundaries can be made to depend upon the velocity of the arm as it is being maneuvered.

Abstract: A spar having fluid flow lines or material conveyors extending along the same is anchored by a ball joint, U-joint, elastic joint or the like to a base on the bottom of a body of water, such as a sea bottom. The spar has a buoyancy chamber near its upper end for applying an upward tension thereto at all times.

Several embodiments of the tension means are disclosed. The fluid flow lines carried by the spar connect a base manifold on the bottom of a body of water with delivery hoses or other conductors which can provide flexibility and are connected to the vessel for the transfer of crude oil and other fluids thereto.

Abstract: A marine loading arm equipped with an improved pipe swivel joint at the outer end of the arm's triple-swivel coupling assembly that functions to connect the outer end of the arm to the manifold flange of a marine tanker. The weight and axial dimension of this improved swivel joint are less than that of conventional swivel joints of the same pipe diameter, so that the coupling flange at the distal end of the triple-swivel assembly rests in a more vertical attitude, thereby easing the task of coupling the arm to the tanker's manifold flange and reducing the moment load imposed on that flange. The improved swivel joint also includes an arrangement for gaining quick and easy access to its packing chamber when replacing the packing between the joint's relatively rotatable elements becomes necessary.
