How is the main drainage system segregated and how are they classified?
By bulkhead stop valves, classified as Circle X-Ray
What type of drainage is utilized in compartments above the waterline?
Gravity drains
Where are most gravity drains discharged to?
Over the side through scuppers
How are portable pumps discharged?
Overboard discharge connections, which have screw caps (not valves), and use a 4 inch pipe

Following an underwater explosion, if there is threat of the ship breaking apart, what is the primary response when possible?
Beach the vessel
Following an underwater explosion, if there is compression damage amidships, the following 6 steps should be taken
- Reduce speed
- Change course to minimize pitch, hogging, and sagging
- Examine for damage, check fuel tanks
- Proceed to safe anchorage
- Commence repairs en route if possible
- Consider beaching if damage is severe or heavy weather is imminent
How is Sagging dangers mitigated?
Correct trim by moving liquid from amidships to fore and aft, or centerfold the high end
How is Hogging counteracted?
Move liquid from ends of ship to amidships, flood amidships tanks
What is the primary purpose of shoring?

Strongback
What is the relationship between the thickness and length of a Shore?
Length can be 2.5 times the thickness - for example, a 4 inch thick shore can be 10 feet long
List 7 advantages to metal shoring to wooden
- Fireproof
- Prefabricated and adjustable
- Stronger
- Saves Space
- Welded shores will not slide or jump
- Repairs can be semi-permanent
- Greater number of types of repairs
What is the disadvantage of using metal shoring vice wood?
Can be spark producing
