The invention relates to equipment for the transfer for fluids, much as oil or gas, e.g. from a platform or buoy located by attachments to the sea bed, but otherwise with complete freedom of movement, due to the action of wind and wave, to a vessel with similarly complete freedom of movement. The equipment includes systems for automatically acquiring a target (10) to which is attached a tage line (11) and a transfer hose line (9), and for automatically transporting that target (10) accurately to a winching system (16) mounted on the said ship. The transfer hose line can be reeled in by the winching system (16) and the fluid transfer hose thus connected automatically to the ship-mounted receiving system. The equipment includes a self-sealing fluid coupling through which fluid flow can take place, and a hose having sufficient length to accommodate the stand-off of the vessel from the platform or buoy. Routine uncoupling is accomplished by reversing the coupling procedure, including the use of the same equipment to replace the target in close proximity to the buoy in a controlled manner. The mechanical configuration of the deck equipment 16 is such that if an emergency occurs, the transfer hose line and the running shackle can be released from their respective clamps (43)(44), thus permitting the transport hose line to pay-out. This would allow all the equipment connecting the receiver vessel with the buoy or platform to fall overboard in a predetermined manner. This procedure maintains the continuous loop which comprises the transfer hose, transfer hose line and tag line, and enables a pick-up to be effected subsequently.

An improved system for effecting open-sea transfer of fluid from a source, such as a moored or anchored oil or gas platform, vessel, buoy or wellhead, subject to wave action to a receiver vessel in open-sea conditions includes: mounted on the receiver vessel a first self-sealing part of a connection
An improved system for effecting open-sea transfer of fluid from a source, such as a moored or anchored oil or gas platform, vessel, buoy or wellhead, subject to wave action to a receiver vessel in open-sea conditions includes: mounted on the receiver vessel a first self-sealing part of a connection means by which fluid may be transferred to the receiver vessel and gantry means movable in both elevation and azimuth; and mounted on the source; hose means having one end thereof connected to the source for the transfer of fluid therefrom and a second self-sealing part of the connection means connected to the other end of the hose means for engaging and automatically mating with the first self-sealing part of the connection means to form a continuous fluid path between the source and the receiver vessel; wherein the improvement comprises: means for at least partially space stabilizing the gantry means; clamping means adjacent said gantry means; target position sensing and acquisition means on said gantry means; and vessel-mounted winding means adjacent the gantry means; and wherein mounted on the source are: a transfer hose line having one end thereof secured to the other end of the hose means; a target device secured to the other end of the transfer hose line such that the transfer hose line may be pulled through the target device when acquired by the acquisition means; and tag line means secured at one end to the target device and extendably secured at the other end to the source, whereby in use with the receiver vessel positioned adjacent the source, the gantry means may be at least partially space-stabilized, the target position sensing and acquisition means on the partially space stabilized gantry means may be aligned with the target device, such that the target device may be acquired by the target position sensing and acquisition means, the gantry means may be actuated so as to cause engagement between the target device and the clamping means, the other end of the transfer hose line may be connected to the winding means and the winding means may draw in the transfer hose line and thereby the hose until the first and second parts of the connection means engage and automatically mate to provide the continuous fluid path therebetween and to couple the hose to the receiver vessel, and whereby the hose may be uncoupled from the receiver vessel in a procedure substantially the reverse of the procedure recited above for coupling the hose to the receiver vessel.
