IffiS 6 Evaluate Mooring System 



Backgroiind 



The mooring system is designed for mooring oil containment 

 boom and other oil spill cleanup equipment. Such a system is 

 usually required when the spill occurs away from shore. The system 

 could moor the boom and work platform, thus freeing the utility 

 boat for uses other than keeping the boom on station, e.g., spreading 

 piston film, spreading sorbent, ferrying personnel and equipment. 

 The mooring system is designed for deployment in 100-ft depth waters 

 while developing a holding capacity equal to that required to moor 

 1000 ft of boom in adverse weather conditions. The system is designed 

 for easy tov/ing behind the utility boat and for continuous line 

 payout when the anchor is dropped. There are four mooring systems 

 available for evaluation. Two are rated at 2,000 lb, one at 5,000 

 lb, and one at 10,000 lb. 



Objective 



The objectives of this element are to: (1) evaluate the following 

 characteristics of the mooring system: compatibility with 36-inch boom, 

 procedures for deploying and retrieving system, and personnel 

 requirements; and (2) to determine the best size mooring system 

 for the intended use. 



Scope of Work 



a. Determine whether the mooring system is compatible 

 with 36-inch boom. 



b. Describe the best method of attaching the mooring system 

 to the boom connectors. 



c. Detejonine whether a special coupling is required to 

 attach the mooring system to the boom connectors. 



d. Determine whether a bridle assembly is required to 

 stabilize the boom. 



e. Determine the number of personnel required to deploy 

 and retrieve the mooring system. 



f. Measure the maximum force which the utility boat can exert 

 against the mooring system.
