The principal action in changing from transit to survival draft in the event heavy weather threatens is __________.

🔍 Key Concepts

• Survival draft vs. transit draft on a mobile offshore drilling unit (MODU) or similar offshore unit • How draft and stability are affected by adding or removing ballast water • What you must do to lower the center of gravity and increase draft in preparation for heavy weather

💭 Think About

• In heavy weather, do you want the unit riding higher or deeper in the water for better stability? • Which operation will increase the unit’s displacement and draft: taking on water in ballast tanks or pumping it out? • Think about the purpose of a survival draft—what condition of stability and motion in waves are you trying to achieve?

✅ Before You Answer

• Be clear on the definitions of ballasting vs deballasting (which one adds water, which removes it). • Relate each choice to whether it will raise or lower the draft and improve or reduce heavy-weather stability. • Consider which actions like hanging off or disconnecting are about moorings/risers, not directly about changing draft.
