The MODU has suffered a casualty which requires an orderly evacuation of the unit using the lifeboats and liferafts. Among the items to accomplish in preparing to evacuate the unit is __________.
• Emergency evacuation procedures for MODUs (Mobile Offshore Drilling Units) • Purpose of securing the unit before abandonment (fire, flooding, pollution, stability, and well control risks) • Typical checklist items before abandoning an offshore unit: shutting down operations, securing equipment, and preparing lifesaving appliances
• When you abandon a MODU in an orderly way, what is your main safety concern: collecting extra samples/equipment, or making the unit safe to leave behind? • Think about what actions help prevent a secondary disaster (like pollution, fire, or loss of well control) after everyone evacuates— which option supports that goal? • Which options are clearly unrelated to immediate life safety or to protecting the installation and environment during an emergency evacuation?
• Identify which choice actually reduces ongoing hazards (machinery, well, environmental risks) if the unit is left unattended. • Eliminate any option that is focused on routine operations or data collection, not on emergency safety actions. • Ask: During a real abandon-unit drill, what do the checklists emphasize doing to the installation itself before everyone gets in the boats?
