We will be switching to this new system soon.

Definition:  A generic term for several classes of self-contained floatable or floating drilling machines such as jackups, semisubmersibles, and submersibles. 

   The subject of Mobile Offshore Drilling Unit consists of  1,640 questions and 0 illustrations which are presented as 82 / 20 question quizzes. If you are studying for your United States Coast Guard MODU exam you should continue working through all 82 of these quizzes until you are scoring 80% or better on all of them. 

   As you work through the quizzes you will find some questions that are very similar in content but may vary slightly in either the wording or in the order in which the answers appear. Work through them anyway. These are not randomly generated quizzes. The questions used in our quizzes are from the National Maritime Centers latest database of questions that are used by United States Coast Guard, USCG, Regional Exam Centers for administering tests and are categorized into their specific subject for targeted study. The online quizzes are presented in an interactive, easy to use, point and click, multiple choice format. After two or three times through a quiz you will see your scores rapidly improve. Move on to the next quiz and repeat the process. Check your score history frequently to see which subjects you may need to review.
