Question 1122 Deck General

The correct answer is B) means of communication between the bridge and engine room. U.S. regulations require any tankship making a voyage of over 48 hours duration to conduct certain tests not more than 12 hours prior to leaving port. This requirement is to ensure the reliable operation of critical systems during the extended voyage. The means of communication between the bridge and engine room is a critical system that must be tested to meet this requirement, as it allows the bridge to monitor and control the engine room operations. The other options, such as the emergency lighting system (A), watertight door to the shaft alley (C), and fire pump relief valve (D), while important, are not specifically required to be tested under this regulation for voyages over 48 hours.
