predictable, and if the spill is planned to be removed in a short time, 

 then a catenary configuration requiring only two mooring systems should 

 be adequate . 



Observations, Comments, and Suggestions 



Based upon CEL ' s test experience, the following recommendations are 

 made : 



1. The length of the mooring line between the buoy and the boom should 

 be as short as possible. An estimated 10 to 15 feet of this line appears 

 reasonable to minimize drift of the boom. The mooring line connecting 

 the boom to the buoy should be 100 percent polypropylene so that it 

 floats freely on water, and facilitates retrieval. 



2 . The location of the anchor should be predetermined from the desired 

 location of the boom and the length of the mooring line. The anchor 

 should be dropped first prior to mooring the line to the boom, per 

 paragraph 3.3.2.1 of reference 8. 



3 . The deployment of the boom and the mooring systems should be 

 carried out simultaneously so that the boom can be secured during 

 deployment, particularly in bad weather, to prevent boom drifts due to 

 winds and currents . 



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

 match appropriate eyebolts. Eyebolts , which may be attached to all 

 connectors prior to boom deployment or to selected connectors only 

 during mooring, should match the shackle suitable for the selected 

 mooring system. 



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

 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 space through which oil could escape due to 

 currents , winds , or waves . 



7. The end connector on the boom should match the bulkhead attachment. 

 The bulkhead attachment has a female connector and, therefore, it must 

 be coupled to a male connector. If the boom to be connected to the 

 bulkhead attachment has a female connector, a "doxible-male" adapter 

 must be joined to the bulkhead attachment. Of course, the towing 

 assembly must be removed prior to securing the boom to the bulkhead 

 attachment.
