Leak categories
Minor, Moderate, Major
Minor leak definition
Hull cracks, broken pipes, loose seems, small holes
Minor leak patch material
Wood plugs, wedges, GRP
Moderate leak definition
Hull or bulkhead opening that cannot be closed
Moderate leak patching material
Require site prep, template, patchs are bulky for one man
Major leak definition
Extensive hull bulkhead damage
Major leak patching
Large scale steel work, extensive diving
Steel patchs
Readily available, easy to work with, strong backed bolted, welding allows semi permanent repairs
Plywood patchs
Used intertidal zone where pressure is low, Small patchs can seal leaks 30” or lower, not a long term solution
What are the most common types of educators used?
S-type; single jet, has built in foot valve to prevent back flow.
Peri-Jet; six nozzles, can pass solid objects up to 2” in diameter.
How do educators operate?
Using the Venturi principle.
Advantages of educators?
- require min. pressure
- are small and compact
- safe in enclosed spaces containing fuel or POL residues
- can driven from the fire main
Cofferdams definition
Temporary water tight extension of the hull to the surface
3 types of cofferdams
Complete, Partial, small
Eductors 2 types
S-type single jet, Peri Jet six nozzels pass 2” solids
Eductors description
Small compact, driven by water pressure, works with POL floating on top, moves abrasives and slurries

What are the types of direct pull systems?
Hydraulic (mainly used) - reads up to 200,000 lbs - survives up to 300,000 lbs
Electrical - 110 VAC or 12 VDC, reads tension to 200,000 lbs.
What is ground tackle systems known as and what are the two types?
“Beach Gear”
Direct pull system
Purchase system
Direct Pull Systems advantages?
- Fewer personnel
- Puller controls can positioned wherever
- Continuos line pull
- Pullers are portable
- No loss of pulling force caused by sheaves
