4. All boom connectors should have sized holes at the bottom 

 end for appropriate size eyebolts. The eyebolts , which may be 

 attached to all connectors prior to boom deployment or to selected 

 connectors only during mooring, should match the shackles suitable 

 for the selected mooring system. 



5. All lines should be faked into a figure eight configuration 

 during storage to minimize twists and risk of entanglement. 



6 . Bulkhead attachments should be prepositioned at all piers 

 where oil spills are expected to occur. The selection of pilings 

 for bulkhead attachments should be carried out carefully to 

 ensure that the selected locations will not leave spaces through 

 which oil could escape due to currents, winds or waves. 



7 . The end connector of the boom should match the bulkhead 

 attachment for proper coupling. 



8. Several different adaptors and boom connectors should be 

 stored at the base to cater to all possible eventualities. 



9. Mooring lines connecting the boom to the buoy should be 

 made from 100 percent polypropylene to ensure that they float 

 on water and thereby reduce the effort required in pulling them 

 up during the deployment and retrieval procedures . 



10. The mooring system design should take into consideration 

 the soil type of the harbor seafloor. The holding power of an 

 anchor in clay or silty seafloor is between one-third to one- 

 seventh its holding power in a sandy seafloor. 



11. A mooring system with an 80-lb anchor was found to be the 

 heaviest two men could deploy and retrieve without a winch. 



This system may be used to hold about 8, 400- lb in a sandy seafloor, 

 and about 1,200-lb in a clay or silty seafloor. 



12 . Under current and wind conditions which may produce forces 

 greater than the holding capacity of the 80-lb anchor, heavier 

 mooring systems requiring the use of mechanical equipment during 

 deployment and retrieval, or multiple anchors in tandem should 

 be considered.

1. The boot assembly investigated in this test and evaluation 

 should be reduced in length and then tested for performance.
