Abstract
An emergency disconnection system for a fluid loading arm includes two valves, a collar which when closed secures the valves together and which when opened allows the valves to disconnect from each other, and an actuator which includes a single rod which is movable axially over a length of travel. A first jack moves the rod over a first portion of its travel to close the two valves and a second jack moves the rod over a remaining portion of its travel to open the collar. The first and second jacks are independently controllable and positioned substantially coaxially relative to each other.
