The main idea is that closing out a Re-Entry Certificate requires sign-offs from all three key authorities who oversee safety, diving operations, and overall authorization. The Re-Entry Control Supervisor is the person responsible for orchestrating and monitoring the re-entry process, ensuring that all safety controls, risk assessments, and procedures are in place and followed. The Senior Diving Supervisor oversees the diving aspects of the operation, confirming that equipment, systems, and dive plans meet safety standards and that the dive team is ready. The Commanding Officer provides the final authorization and accountability, giving the official clearance to proceed and sign off on completion.

Having all three signatures ensures that every critical angle—controls and procedures, diving safety, and command-level approval—has been reviewed and approved. Without any one of these roles, there would be a gap in oversight and authorization, which is why this combination is the correct choice.
