Question 4317 Deck General

The correct answer is C) 6 hours. The time required to place the DEEP DRILLER at survival draft from the drilling mode to counter heavy weather is 6 hours. This is based on the regulatory requirements for offshore supply vessels and mobile offshore drilling units (MODUs) to have the capability to quickly transition to a safe mode of operation in response to heavy weather conditions. The regulations specify that this transition should be completed within 6 hours to ensure the vessel's safety and stability. The other options are incorrect because 2 hours would be too fast for a large MODU to complete this complex transition, while 4 and 8 hours would not meet the regulatory requirement of 6 hours.
