The DEEP DRILLER is loaded as shown in the Sample Load Form #3 (Preparing to Drill). According to the deck load graph, how much additional deck load could be added to the unit?

Correct Answer: Option A — 526.87 long tons

Deck load capacity graphs account for structural strength limits and intact stability constraints at specific operating drafts. Based on Sample Load Form #3 for the DEEP DRILLER preparing to drill, evaluating the allowable curve permits an additional 526.87 long tons of deck load.
