D-399; Rotary Table--Nat''l C-375; Top Drive--Varco.DERRICK: 147'' x 30''; 1,000,000 lb hook load.BOP SYSTEM: Two double 13 5/8", 10,000 psi wp;one 13 5/8'', ametekhydraulichandpump 5,000 psi wp annular.CRANES: Three LeToumeau, PCM-120 AS w/100''boom, 50 short tons @ 24''.REMARKS: Formerly Glomar High Island VI. The EFI system contains an electronic control unit that can monitor ametekhydraulichandpump the equipment''s functions, including dash displays (engine temperature, speed hours); analog/digital inputs (vehicle incline sensor, safety interlocks, vehicle and/or blade speed); diagnostics (air cleaner status, oil change intervals, operator safety warnings); and electronic governor/throttle ametekhydraulichandpump controls (ground speed control, cut height ''control).The 725 cc Command Pro 26 EFI produces 41.6 lb.ft. torque at 2200 rpm, has a compression ametekhydraulichandpump and ametekhydraulichandpump ratio of 9:1 and utilizes Kohler''s nickel-silicon plated Power-Bore cylinders for longer cylinder life. For flux-cored-arc welding, shops use CV or CC types, 300 to 1,500 A, 25 to 50 V, rated 60- to 100-percent-duty cycle. CV types are more popular because wire-feed speed, set before welding, controls welding current. Cc types require a variable-speed or voltage-sensing wire feeder.Gas-tungsten-arc welding (GTAW) requires a constant-current (AC or DC) power supply with a ametekhydraulichandpump steep volt-amp curve to minimize current change for variation in voltage or arc length. They come rated to 1,500 A, 10 to 75 V, at 40- to 100-percent-duty cycle. Most GTAW power supplies come equipped with high-frequency circuitry for arc initiation and stabilization, gas valves, and cooling-water ametekhydraulichandpump valves for high-current welding. High-frequency arc start is useful when the maximum open-circuit voltage allowed by NEMA standards, 80 to 100 V, will not establish ametekhydraulichandpump and maintain a stable arc.
