Question 4266 Deck General

The correct answer is C) 100 knots. The Coastal Driller is a vessel type that is assumed to have a maximum wind velocity of 100 knots when determining the limits of elevated service. This is based on the regulations and standards set forth by the US Coast Guard for this type of vessel. The 100 knot wind velocity is used as a conservative design standard to ensure the Coastal Driller can safely operate in high wind conditions. The other answer choices are incorrect because 70 knots (option A) and 50 knots (option B) are lower wind velocity thresholds that would not be appropriate for the Coastal Driller. Option D is also incorrect, as the 100 knot wind velocity is a fixed standard, not something that varies with allowable wind and wave charts.
