Abstract: A system and method are used for dispatching a rescue flotation device to an individual who has fallen overboard from a ship. A water-activated transmitter is carried or worn by each and every passenger on a given ship. Upon detecting moisture, the transmitter is activated to send a data signal to a radio signal receiver on the ship. The contents of the data signal may be the location and/or coordinates of the victim, as determined by triangulation of the signal, a GPS receiver and/or radar. Upon transmission of the data, a rescue flotation device or vessel is automatically deployed from a portion of the vessel into the water. The rescue device may be dispatched from a portion of the ship nearest to the determined location of the victim, and/or the rescue device may be self-propelled such that it navigates to the approximate location of victim.

Abstract: A new power tong for rotating tubular members for make-up (connection) and break-out (disconnection) operations. In one aspect such a tong has at least one movable jaw with a smooth surface gripping element thereon and pre-load apparatus for applying a pre-load force to a movable jaw so that the jaw does not slip on a tubular to be rotated and so it does not mark or damage the tubular. In one aspect the pre-load apparatus includes a first pre-load device at one end of a movable jaw for breakout operations and a second pre-load device at another end of the jaw for make-up operations. In one aspect a power tong which has unique smooth surfaced jaw inserts made, e.g., of aluminum. In one aspect a single pivotable pre-load cylinder, fixed to rotary, pivots for pivotable connection to one jaw or the other. This can be done manually or a powered smaller piston/cylinder may be used to pivot the pre-load cylinder.
