Claim 23:
24. A method for the off-loading of hydrocarbons from an offshore floating production storage and offloading vessel (FPSO) to a shuttle tanker comprising:
providing a hose defining a conduit for the passage of hydrocarbons between a first end and a second end and having at one of the said ends a valve arrangement comprising:
a linear valve comprising a linear valve actuator movable between a first position whereat the valve is closed and a second position whereat the valve is open;
a secondary valve comprising a secondary valve actuator movable between a first position whereat the valve is closed and a second position whereat the valve is open;
wherein the linear valve actuator and the secondary valve actuator are operatively coupled such that movement of the linear valve actuator between the first position and the second position effects a corresponding movement of the secondary valve actuator between the first position and the second position; and
the secondary valve comprises a rotating valve having a secondary rotating valve actuator carried within a valve housing that is mounted to be rotatable between a first position whereat the valve is closed and a second position whereat the valve is open;

fluidly connecting the other end of the hose to an FPSO so as to be in fluid communication with a fluid reservoir therein;
coupling the first end of the hose to a shuttle tanker and thereby causing the valve arrangement to open, and to effect a fluid connection between a fluid storage on the shuttle tanker and the fluid storage on the FPSO;
transferring fluid from the fluid storage on the FPSO to the fluid storage on the shuttle tanker.
