Steel buoys currently used by NFEC field activities were built in 

 large quantities during World War 1 1 . The surplus buoys were stored for use 

 as required, and now these buoys have almost been exhausted. A few Mark 1 1 

 peg-top mooring buoys (Federal Stock Catalog No. 2050-275-7681) are still 

 available at the Construction Battalion Center, Port Hueneme at a nominal 

 price of $2,120 each. Before use as part of a mooring, these buoys require 

 removal of the shop coating and recoating with a system suitable for marine 

 exposure. Also, modification of the buoy might be necessary for a particular 

 type of mooring operation. For example, at San Diego, the hawse pipe would 

 be replaced with a tension bar. It is estimated that the complete fabrication 

 of a new steel buoy ready for use in San Diego would cost between $10,000 

 and $12,000, a price comparable to that of a plastic buoy. Thus, the relative 

 maintenance costs of the two types of buoys would be the determining factors 

 in the selection of either type of buoy once the limited supply of steel buoys 

 is exhausted. 



Maintenance of Buoys 



Steel Buoys. It is difficult to separate the costs associated with maintain- 

 ing mooring buoys from those of maintaining the rest of the mooring since both 

 are rehabilitated together. Cost data were assembled for removal, overhaul, and
