Slack

Ease out line so no strain is taken

3

Hold

Hold line even though it may part

4

Check

Keep strain paying out to prevent parting

5

Up Behind

Main bow Rollers, weight, what do they do

150 tons, Mechanical lifts, Heave on wire ropes or chain rigged on a sunken object

13

Leak categories

Minor, Moderate, Major

14

Minor leak definition

Hull cracks, broken pipes, loose seems, small holes

15

Minor leak patch material

Wood plugs, wedges, GRP

16

Moderate leak definition

Hull or bulkhead opening that cannot be closed

17

Moderate leak patching material

Require site prep, template, patchs are bulky for one man

18

Major leak definition

Extensive hull bulkhead damage

19

Major leak patching

Large scale steel work, extensive diving

20

Steel patchs

Readily available, easy to work with, strong backed bolted, welding allows semi permanent repairs

21

Plywood patchs

Used intertidal zone where pressure is low, Small patchs can seal leaks 30" or lower, not a long term solution

22

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.

23

How do educators operate?

Using the Venturi principle.

24

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

25

Cofferdams definition

Temporary water tight extension of the hull to the surface

26

3 types of cofferdams

Complete, Partial, small

27

Eductors 2 types

S-type single jet, Peri Jet six nozzels pass 2" solids

28

Eductors description

Small compact, driven by water pressure, works with POL floating on top, moves abrasives and slurries

29

Direct pull system
Purchase system

33

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
