🔍 Key Concepts

• Meaning of "KEEP CLOSED" markings specifically on Mobile Offshore Drilling Units (MODUs) per 46 CFR • Different purposes of doors: watertight integrity, fire protection, and gas-tight/airtight separation • Where poisonous vapors vs flammable gases vs fire/heat control are normally addressed on offshore units

💭 Think About

• Ask yourself: On a MODU, in an emergency, why would the crew be ordered to keep certain doors closed at all times? What hazard are they primarily trying to control? • Think about which type of door would need a clear sign because leaving it open would defeat a major safety boundary in the structure of the unit. • Consider which of the listed hazards is usually controlled by ventilation and gas-detection systems rather than by simple “KEEP CLOSED” signs on doors.

✅ Before You Answer

• Check which systems are used to control flammable gases and poisonous vapors (ventilation, gas detection, purging) versus physical barriers like doors and bulkheads. • Review the difference between a watertight door and a fire door on offshore units and what each one is designed to protect against. • Ask: If this door is propped open during normal operations, which critical safety function of the MODU’s structure would be lost immediately? That is the function the marking is protecting.
