Battery Limit Responsibilities Division

The following description of the typical items between the Process Battery Limit (PBL) and Construction Battery Limit (CBL) indicates the Units’ responsibility. Where this typical list causes a design, procurement, fabrication or construction conflict, the ISBL (Inside Battery Limit) and OSBL (Outside Battery Limit) Units will address on a case by case basis. The typical Battery Limit Schematic is shown below.

Case by case basis

10 EHT design 1. HMS has overall design responsibility, but must be supported by ISBL

and OSBL (U80) between PBL and CBL2. Segment of EHT between Spectacle Blind and CBL is part of ISBL EHT

and is not intended to be separately controlled
