Figure F19. This figure, which has been available on the ship for many years, summarizes some of the significant depth dimensions on the ship. The drillers commonly use the depth below the dual elevator stool (DES). The echo sounder depth corrected by Matthews' tables gives the depth to the sonar dome. DP = dynamic positioning room, PDR = precision depth recorder.
