Illustration RP0028: the U.S. Coast Guard has not released this illustration. #23 As Chief Engineer or First Assistant Engineer you should be familiar with the six motions of a vessel. Which of these motions affects the governing "longitudinal" stability? #24 As Chief Engineer of an ocean going passenger vessel, it is important to know the effect of trim and stability of your ship in the event of damage to a compartment. To minimize the impact of flooding in the event of a grounding, what should be your ship's safe practice regarding watertight doors and hatches? #25 The important stability parameter 'KG' is defined as the __________. #26 The symbol shown in the illustration and used as a reference from which the height of the center of gravity is measured, is item number __________. SF-0022 #27 As Chief Engineer you should understand the concept of corrective measures and their purpose. The following four actions will have which affect on the vessel? 1) Add weight low and symmetrically about the center line. 2) Remove high weight symmetrically. 3) Move weight down symmetrically. 4) Eliminate any free surface present. #28 Which abbreviation represents the height of the center of buoyancy? #29 As Chief Engineer your vessel has been damaged and one compartment has partially flooded. You understand that you have lost buoyancy and have added weights. If transverse stability in the flooded condition is poor or negative, every effort should be made to reduce the free surface and to lower the center of gravity. Of main importance is for you to assure which of the following is maintained? #30 If a vessel initially has no list and no significant trim, which of the developments shown in the illustration will result in the greatest list? SF-0025
