  If you are studying for a United States Coast Guard Engineering License exam which includes these modules, you should  work through these questions in the online study until you are scoring 80% or better on them.

List of subjects required: (Click Here to See)

  QMED is an abbreviation for Qualified Member of the Engineering Department.  There are a number of different "QMED ratings."  The most common for both steam and motor (i.e., diesel propelled) ships is the "Oiler" rating.  Many older steam vessels also require the "Fire­man/Watertender" rating.  Tank­ships require "Pumpman," and vessels with electrical cargo gear carry one or more crewmembers with an "Electricians" rating.  Additional ratings include "Refrigeration Engineer," "Deck Engineer," "Machinist," and the "Junior Engineer."  If you obtain all of these ratings you may obtain a rating of "QMED - All Ratings."

   A special QMED rating was created for diesel pow­ered off­shore supply vessels working in the offshore oil in­dustry and is called Oiler (OSV).  It is only valid on off­shore supply vessels and not on vessels such as diesel ferries.  Two additional ratings were created for modern power plants with varying degrees of automa­tion.  These ratings are the "Engineman" and the "Deck Engine Mechanic."  These two ratings do not require additional testing after you obtain the required ratings, experience, and training specified in Coast Guard regulations.

  The test required for any rating is composed of two modules (i.e., parts).  The first module is called "QMED - General."  You must pass this module before you can take the module for the specific rating (or ratings) you desire.
