w/100'' boom; One Skagit Model 353, 34 t @ 30'' w/80'' boom.OTHER DATA: Same as Ocean Nugget, except Varco SDS-1 side drive.WORK AREA: Gulf of Mexico.OCEAN SPARTANRIG DESIGN: Friede & Goldman Ltd., L-780CONSTRUCTION: Swedeyards Gotaverkan, Arandal, Sweden, 1980.PERFORMANCE: Water depth--250''; Drilling depth--20,000''.QUARTERS: 76 persons, plus 2-man sick bay.HULL: 180''x 175'' x25''.VARIABLE LOAD: 4,190 kips.HELIPORT: 62'' diameter for S61.STORAGE: Mud & Cmt Bulk--9,670 cf, plus 3,000sacks; Liquid Mud--1,985 bbl; Water for Drilling--5,450 * Reduces the size of the etched zone for improved cosmetics.Less EN time improves cleaning action to remove heavier oxidation, drillpressreview lessens penetration, and widens the bead profile.Inverter-based machines also let operators adjust welding-output frequency from 20 to 250 Hz. Decreasing frequency products a broader arc cone, which widens drillpressreview the weld-bead profile and better-removes impurities from the surface of the workpiece. It also transfers the maximum amount drillpressreview of energy to the workpiece, ideal for work requiring heavy drillpressreview metal deposition.Increasing frequency produces a tight, focused arc cone. This narrows the weld bead, helpful when welding in corners and drillpressreview on root passes and fillet welds. Independent amperage control of the EN and EP portions of the AC cycle allows the operator to fine-tune the amount of energy directed into the workpiece, as well as take heat off of the tungsten electrode. A basic, professional-quality AC GTAW power supply lets the operator adjust for variables: amperage, balance control, and shielding-gas pre-flow and post-flow time. The course runs 6,800 yards along the creek. Par is 72. Greens fees are $100 to $120. There''s also a nine-hole, par-three course that can be played at night, under floodlights.The city''s premier night golf experience, however, is at the Nad Al Sheba Club (formerly the Dubai Golf and Racing Club). A full-length course (18 holes, 6,428 yards, par 71), Nad Al Sheba has taken pains to make sure every hole is illuminated.There''s no problem with shadows because there are no trees on the course. However, the lack of trees means players must contend with the wind, so those experienced with links-style courses will particularly enjoy Nad Al Sheba.
