Question 4761 Deck General

The correct answer is C) countermeasures. In the analysis of damaged stability for the DEEP DRILLER, the beneficial effects of moorings and countermeasures are disregarded. This is in accordance with the stability criteria specified in the U.S. Coast Guard regulations for mobile offshore drilling units (MODUs). The regulations require that the damaged stability analysis be conducted without considering the stabilizing effects of moorings or any other countermeasures, such as water ballast or active stabilization systems. This ensures that the stability assessment is based solely on the inherent characteristics of the vessel's design, providing a conservative evaluation of its ability to withstand damage. The other options, such as wind strength (A) and the vertical (B) or horizontal (D) area of the platform, are not the correct factors that are disregarded in the damaged stability analysis for the DEEP DRILLER.
