4. The deck of the UTB should be treated to produce nonskid surfaces. 



5. All lines should be made from 100 percent polypropylene to reduce 

 the effort required in picking them up during the deployment and 

 retrieval procedures. 



6. A set of three 6-gal fuel tanks should be provided on each UTB to 

 minimize disiruptions of the oil removal operations due to shortage of 

 fuel. 



7. To maximize useful life of the outboard engines, they should not be 

 run continuously at full throttle . 



8. The deployment and retrieval of the UTB with a crane is easy, fast, 

 and safe. It is therefore, recommended that a crajie be used in all 

 deployments and retrievals of the UTB. 



9. All towing should be conducted from the samson post to enhance 

 stability and maneuverability of the UTB. 



10. A towing line length of 50 ft appears adequate. A reel should be 

 provided at the samson post for storage of the towing line and to 

 prevent entanglement. 



11. The UTB could be used to tow a full oil storage bag from the oil 

 spill site to the pier, to connect and disconnect boom sections, and 

 to tow a flattop boat. 



12. The UTB appears to lack stability and power for cleanup operations 

 lander less than perfect weather conditions. Extreme caution is required 

 even under near perfect weather conditions. 



13. The 2,000-lb mooring system evaluated in this test program could be 

 safely deployed and retrieved from the UTB under calm weather conditions. 

 However, the 5,000-lb and 10,000-lb mooring systems could not be safely 

 deployed and retrieved. See the section "Evaluation of Mooring Systems" 

 for further details. 



14. If possible, the outboard engines with outboard cooling systems 

 should be replaced by engines with closed cooling systems to ensure 

 trouble-free operations in harbor oil spill removal operations.
