Deck General USCG Q#3339 (Set 106)

The COASTAL DRILLER is experiencing a single amplitude roll angle of 1 degree and a roll period of 7 seconds. What is the maximum recommended water depth for elevating?

Official USCG Answer & Rule Citation

Correct Answer: Option C — 150 feet

Standard operational guidelines and stability criteria for self-elevating MODUs correlate motion parameters like roll period and single amplitude roll angle with safe jacking water depths to prevent resonant dynamic amplification and leg overstress during elevation.
