🔍 Key Concepts

• Liftboat jacking operations and why stability and structural loading are critical when changing leg position • Standard personnel safety procedures during potentially hazardous operations on deck • How simultaneous leg movement vs. single-leg movement affects the vessel’s structure and balance

💭 Think About

• Think about what could happen to a liftboat’s stability and hull stress if only one leg is moved while the others stay fixed. • Consider where crew members are safest when the hull begins to move relative to the seabed-supported legs. • Ask yourself which option best reduces the risk of someone being trapped, crushed, or injured if there is unexpected movement or equipment failure.

✅ Before You Answer

• Verify which action keeps all personnel clear of pinch points and moving structure before jacking starts. • Check which choice aligns with standard jacking procedures for keeping the unit as even and stable as possible. • Eliminate any options that would increase risk by adding unnecessary motion, opening critical spaces, or creating uneven loading.
