| How may a suspected tube leak on a shell-and-tube jacket water cooler most easily be located? |
| A) Isolate, drain, and dry the salt water side of the heat exchanger. Remove the water box inspection plates. Visually inspect the tube sheets for signs of seepage at each of the tube ends. |
| B) Isolate, drain, and dry the salt water side of the heat exchanger. Pressurize the seawater side with compressed air. Visually inspect the jacket water expansion tank for bubbles. |
| C) Isolate, drain, and dry both the salt water and jacket water sides of the heat exchanger. Remove the water box inspection plates. Visually inspect the tube sheets for signs of seepage at each of the tube ends. |
| D) Isolate, drain, and dry the jacket water side of the heat exchanger. Remove the shell inspection plates. Visually inspect the tubes along the tube lengths for seepage. |
