13. The holding capacities of the three mooring systems were 

 estimated as follows :

14. In most harbors, the mooring systems evaluated in this 



test program are not likely to be able to hold a boom in a catenary 

 configuration \ander winds and/or current conditions. 



15. The heaviest mooring system that could be deployed and 

 retrieved from a FTB by two men, without a winch, was determined. 

 It includes an 80-lb Danforth anchor, a 10-ft long, 3/4-inch 

 link chain, and a 420- ft long, 1-1/8-inch-diameter nylon mooring 

 line. This system is expected to hold about 8,400-lb in a sandy 

 seafloor. 



Sorbent Distribution System 



1. To minimize the risk of sorbent dust generation under wind 

 conditions, a boot assembly of the type investigated during 

 this test and evaluation is necessary. 



2. If breathing masks and protective goggles are worn during 

 the time the sorbent system is in use, then the modification 

 of the sorbent system tested by NAVWESA, reference 8, may not 

 be necessary. 



3. Larger size EKOPERL particles may reduce the dust hazard.
