A hot stab is a type of subsea connector specifically designed to be easily inserted and removed by a remotely operated underwater vehicle (ROV) manipulator arm. The hot stab is the connector which supplies remote utilities. It is normally inserted into a port after removing the plug stab, which is left in the port when the hot stab is disconnected, to keep the port clean and free of fouling when not in use. The alignment is generally not critical for insertion, and the stab is guided into the port by the port geometry, which tends to be concentric cylinder and cone sections, tapering down from the handle end to the tip, with a series of O-ring seals separating the ports or contacts spaced along the length. The stab may be locked into place or may require the ROV to hold it in place while it is in use.[1][2][3][4]
