                       Subpart 111.10_Power Supply

 

Sec. 111.10-9  Ship's service supply transformers; two required.



    If transformers are used to supply the ship's service distribution 

system required by this subpart for ships and mobile offshore drilling 

units, there must be at least two installed, independent power 

transformers. With the largest transformer out of service, the capacity 

of the remaining units must be sufficient to supply the ship service 

loads.



    Note to Sec. 111.10-9: A ship's service supply system would consist 

of transformers, overcurrent protection devices, and cables, and would 

normally be located in the system between a medium voltage bus and a low 

voltage ship's service switchboard.
