Which clock-face fitting is designed to resist direct projectile impact?

• A. 3 O'Clock
• B. 6 O'Clock
• C. 9 O'Clock
• D. 12 O'Clock

Answer: (D)

Protection of openings against direct hits depends on how the fitting is reinforced and where it sits in the ship’s structure. The clock-face fitting at the 12 o’clock position is built to withstand direct projectile impact because it sits in a position that’s more shielded by deck plating and adjacent structural members, and its closure is designed to resist a direct hit. The other clock-face positions are typically used for access or hose connections and aren’t reinforced to endure a direct projectile strike to the same extent. So, the top (12 o’clock) fitting is the one designed for direct impact resistance.
