Which official must approve changes that affect structural integrity, such as removing a watertight bulkhead, for compliance?

• A. Captain of the Port
• B. Harbor Master
• C. Officer in Charge, Marine Inspection
• D. Coast Guard Sector Commander

Answer: (C)

When a modification could affect a vessel’s structural integrity, approval must come from the Officer in Charge, Marine Inspection. This Coast Guard official is responsible for reviewing alterations to a vessel’s structure and subdivision to ensure continued compliance with safety regulations and that the ship remains seaworthy. Removing a watertight bulkhead changes subdivision and flood protection, which directly impacts survivability, so the plans and calculations are evaluated and a determination is made about whether the change can proceed and what conditions must be met. The OCMI may require drawings, calculations, and surveys and will issue the necessary certification or limitations after review. Other officials, like the Captain of the Port or Sector Commander, oversee broader port safety and operations but do not individually approve alterations that affect a vessel’s structural integrity.
