An oil storage terminal will usually have an electric power sub- 

 station on site. The substation is necesary to step-down high voltage 

 power so it can be used to power the terminal's many pumps. From 5 to 

 15 megawatts of power may be needed in a large storage or transfer 

 terminal . 



The volume of storage necessary for a storage terminal serving 

 refineries is dependent on the volume of flow between the terminal and 

 the refineries, the size of the tankers served and the frequency of 

 their arrival, and the duration of bad weather shutdowns. 



Shown in Table 15 are the storage requirements related to where the 

 petroleum is pumped from the vessel and the daily volume of oil handled
