Oakum Spun Tar

Oakum is made up of short lengths of shredded rope or hemp fiber that has been oiled or tarred. It is used in pipe patching operations as caulking or as a gasket when applying soft patches. In plugging operations it is used to plug holes and wrap around a plug or wedge prior to inserting into a split seam or crack in damaged decks, bulkheads and overheads. Oakum is supplied in either a box of three 5-pound rolls or one 50-pound roll.

Only one pound is required in the pipe patching, plugging, and repair locker tool kits and should be stored in a protective package.
What is this? Define.
When dewatering a space with an eductor, what effect takes place? Describe.
Venturi effect. Pipe limits flow rate and creates vacuum for sucking.
Name the bolts used to hold bucket and box patches in place.
Hook bolts (J,T,L)
What is "marline"?
Thin, two-ply twist tarred hemp used in DC applications.
Define the "run".
The run is the distance horizontally from the bulkhead to the anchor point, minus the thicknesses of the strongback and the crosspiece.
Name and describe the 4 types of ruptures.
Simple, compound, severed, elbow
Why is oakum used to seal patches?
It is good for caulking or as a gasket to seal patches.
How much larger than the rupture should a plug be?
If the hole has a diameter of 2", the appropriate plug should have a diameter of 4".
Describe the responsibilities of the shoring watch personnel.
Monitor the effectiveness of shoring, report problems and make temporary improvements.
Describe strongbacks and what they are used for.
-Distributes pressure and serves as an anchor
-Same material as shores
Heavy planks, steel bars and -iron pipe may also be used
What is the formula for determining shoring length?
Shores should be cut no longer than 30X the minimum butt thickness.
The angle of the shore should not exceed _____ degrees.
90 degrees
How long before an EWARP is ready to use?
30 minutes (patch becomes solid in 15 minutes)
