Question 106 Deck Safety

The correct answer is D) All of the above. The maintenance requirements for ships under the Global Maritime Distress and Safety System (GMDSS) are designed to ensure the reliability and functionality of the onboard equipment. The explanation is as follows: 1) Shoreside maintenance and scheduled tests and inspections are required to verify the proper operation of GMDSS equipment. 2) Having a person onboard with a GMDSS maintainer's license ensures that the necessary maintenance and repairs can be performed as needed. 3) Redundancy of critical GMDSS functions, such as having multiple transmitters or power sources, helps meet the maintenance requirements by providing backup systems. 4) Together, these three elements - shoreside maintenance, onboard maintenance by a licensed technician, and equipment redundancy - collectively fulfill the comprehensive maintenance requirements for GMDSS-equipped vessels.
