The class will be split between into two portions: One on Weight Control and the other on Weight Estimating. The Weight Control portion will progress from an in-depth review of the fundamentals of Weight Control, through how to identify weight margins for Naval surface ships, ending with a presentation on Submarine weight control and stability. The processes covered in the class include how and when weight estimates are prepared; how design and building weight margins are established; and how to track weight trends. The class will describe the appropriate weight control for the life cycle of the ship from early stage design through deactivation for ships under NAVSEA cognizance.
