  • Drilling advances

    Robert E. Snyder, Executive Eng. Editor

    Rig Directory time again. This issue contains World Oil’s Marine Drilling Rigs 2003/2004, a 64-page listing of 625 mobile offshore drilling units separated into four categories: jackups, semisubmersibles, drillships/ barges, and submersibles. It’s been a quiet year for offshore rigs; there are 10 fewer listings this year, and the October Offshore Rig Locator (ORL) shows 18 rigs of the above categories under construction, vs. 23 a year ago. But overall utilization of all mobile offshore rigs improved slightly, to 70.5%, vs. 68.6% last October. The Gulf of Mexico was up about 9%; the North Sea was down about 5%, with a few less rigs in each area.
