🔍 Key Concepts

• Weathertight vs. watertight closures and how they are defined in regulations • The specific performance requirement for a weathertight door on a MODU (Mobile Offshore Drilling Unit) under wind and wave action • The difference between a condition defined by wind speed and a condition defined by sea state/sea condition

💭 Think About

• Ask yourself: does the regulation tie the requirement for a weathertight door to a specific wind speed, or does it describe performance in more general environmental terms? • Consider how doors are tested or certified: are they usually rated by maximum wind speed or by their ability to resist green seas and spray? • Think about why the question is mentioning exact wind speeds—are those numbers likely to come directly from the regulation, or are they there to distract you from the actual wording used in the rule?

✅ Before You Answer

• Review how "weathertight" is formally defined in 46 CFR and how it differs from "watertight" • Check whether the MODU requirements specify exact knot values or instead refer to sea conditions or exposure to weather • Verify that the option you choose matches the wording style typical of CFR/IMO regulations, not something that sounds like an arbitrary test condition
