WBS 4 Evaluate Flattop Boat 



Backgroxmd 



Flattop boats used in harbor oil spill recovery operations 

 should be light-weight, easily maneuverable, and have a low 

 freeboard to facilitate work close to the water. They can be 

 used to haul boom to a spill site, to store boom, and to carry 

 any required auxiliary equipment. Flattop boats can also be 

 used as a work area from which to operate some of the recovery 

 equipment, i.e. deploy and retrieve sorbents. 



Objective 



The objective of this element is to evaluate the following 

 characteristics of the utility boat: (1) structural integrity, 



(2) stability and buoyancy of various weight distributions, 



(3) capacity for storing boom and oil recovery equipment, (4) 

 adequacy of engines, (5) maneuverability and ease of handling 

 in water, (5) ease of handling and transporting on land, (7) 

 feasibility of deploying and retrieving boom, and (8) storage 

 method (in water or on land) . 



Scope of Work 



a. Determine whether the means of attaching the working 

 surface of the flattop boat to the pontoons is structurally 

 adequate . 



b. Determine whether the strength of the working surface 

 of the flattop is adequate and whether the working surface is 

 sufficiently dent resistant. 



c. Determine whether the flattop boat is sufficiently 

 stable and buoyant under various weight loadings with boom. 



d. Determine how many feet of 36-inch boom can be stored 

 on the flattop boat, up to a maximum of 1000 ft. 



e. Determine the minimum turning radius, the maximum 

 speed, and ease of handling in water with self-propulsion and 



when towed with the utility boat. Also determine its maneuverability 

 when towed by a utility boat. 



f. Determine handling methods on land and transportation 

 requirements on land.
