Question 3496 Deck General

The correct answer is B) 95 feet. The reasoning is based on the stability criteria for mobile offshore drilling units (MODUs). With a single amplitude roll angle of 3 degrees and a roll period of 10 seconds, the maximum water depth that can be used for going on location is 95 feet. This is because the stability of the COASTAL DRILLER must be sufficient to prevent excessive motions and potential capsizing in the given environmental conditions. The other options are incorrect because 45 feet (A) is too shallow, 145 feet (C) and 245 feet (D) are too deep for the given roll characteristics, and would not meet the stability requirements for safe operations.
