    A[Identify weathertight door\nin exposed superstructure] --> B[Check gaskets & clamping devices\npermanently attached]
    B --> C[Close door and secure\nfrom both sides]
    C --> D[Conduct hose test\nfrom outside]
    D --> E[Verify no water penetration\nat any point]
    E --> F[Record test in\nmaintenance log]

• Test method: hose test from the outside
• Instrument: International Convention on Load Lines, Regulation 12
• Pressure: water pressure per specifications acceptable to IMO
• Purpose: verify weathertightness of access openings in bulkheads at ends of enclosed superstructures
• Location: exposed positions above the freeboard deck
• Construction check: gaskets and clamping devices permanently attached
• CE action: ensure test is done, record in maintenance log, verify operation from both sides
