scope:

The requirements of this guide are intended for installations of a variety of hybrid electric power systems (HEPS) such as combination of conventional power generation (generator, shaft-generator), energy storage system (battery, supercapacitor), fuel cell power system, and other technologies {e.g. solar and wind (electric) power} on marine and offshore installations.

The integration of these conventional power generation and alternate power sources on a vessel or unit is also known as the Integrated Electric Power System (IEPS) for the purpose of this Guide.

The integrated electric power system is utilized for powering the vessels or units' essential and/or nonessential service loads.

The unique requirements for the design, installation, and testing of HEPS on yachts are also addressed.

The scope of this Guide also encompasses HEPS with integration of lithium-ion battery systems, supercapacitor systems, and fuel cell power systems as detailed in the applicable ABS Guides as referenced in 1/11.1.
