Pipe-handling system enhances safety ///

Weatherford’s Iron Derrickman Plus pipe-handling system enables hands-free handling of tubulars on offshore jackup or platform drilling rigs. This patent-pending, racking-board-mounted system lifts up to 23,000 lb (10,433 kg) and eliminates the need for personnel on the derrick or on the drill floor when tripping or making connections, Fig. 1. Designed to mount into existing offshore jackup or platform drilling rigs, the system vertically lifts double and triple stands of drillpipe up to 10-in. (254-mm) diameter, and racks these stands into racking-collar fingers on the well-center side of the system. The design combines innovative mechanical engineering, positive control of hydraulic closed-loop proportional circuitry, electrical remote motion controls, radio, and a direct-wired operator’s panel, giving the operator an intuitive feel of all movements. Applications include offshore jackup and platform drilling rigs and any closed-derrick rigs.
