Operational and logistic improvements for the equipment being 

 furnished to Naval activities by NAVFAC were addressed during Phase II. 

 During Phase III, currently in progress, oil containment booms and 

 skimmers which have become available since the conclusion of the 

 Phase I have been analytically evaluated. Based on this evaluation, 

 one containment boom and three skimmers have been selected for testing. 

 Tests of selected utility equipment are reported in this Technical Note. 



DISCUSSION 

 General Comments 

 Equipment 



NAVWESA completed a number of tests, reference 8, which were 

 included in CEL's proposed test program of January 1975, reference 3. 

 These tests were, therefore, deleted from the revised test program, 

 reference 6. In view of these revisions, the test program carried out 

 by CEL complemented work reported in reference 8. 



The utility boats (UTB) , the flattop boat (FTB) , and the 75 and 

 85 hp outboard engines for these boats were purchased prior to the 

 availability of reference 8 test data. Therefore, information on the 

 effectiveness of various outboard engines was not available to assist 

 CEL in selecting the best possible outboard engines for this evaluation. 

 A 5,000-lb and a 10,000-lb mooring system were purchased by CEL. Two 

 2,000-lb mooring systems were made available to CEL by NAVFAC. The power 

 assistance unit (PAU) used in these tests was developed by Murphy Pacific 

 Marine Salvage Company for CEL under contract, and modified by CEL to 

 enhance performance. Because the test plan did not include evaluation 

 of booms, 300-ft lengths of three different booms, 48-inch Kepner Sea 

 Curtain, 36-inch Bennett Inshore Oil Boom, and 36-inch Bennett Class III 

 U.S. Navy Boom (BM-74-U.S. -030-01) , purchased by CEL earlier, 

 were considered to be adequate for this evaluation. For the Kepner Sea 

 Curtain boom, flotation is provided by enclosed cylindrical logs. For 

 the Bennett Inshore Oil Boom, flotation is provided by enclosed 

 rectangular logs. However, for the Bennett Class III U.S. Navy Boom, 

 flotation is provided by semi-cylindrical logs attached to both sides 

 of the boom by plastic straps. 



Procedures 



Early in the evaluation it became evident that time and manpower 

 required to complete any element of the utility equipment test program 

 depended largely upon (i) the physical strength of each member of the 

 crew, (ii) the exposure and training of the crew in handling equipment 

 and their familiarity with the procedures, (iii) the motivation of the
