C. It resulted entirely from crew error in tethering incorrectly

D. It was an unavoidable consequence of Southern Ocean racing that no procedural change could have prevented

A. Nothing — a test lift can proceed immediately after repairs

B. Testing should wait until cargo operations begin

D. Only the crane operator needs to be aware the lift is happening

A. Who must remain clear of the exclusion zone while the lift takes place
