ISO 16315:2016(E)
Introduction
Electrical propulsion systems are becoming more common in recreational craft and other small craft
and propulsion system voltages of up to AC 1 000 V and DC 1 500 V are possible together with variable
speed drives operating at frequencies which differ from 50/60 Hz or DC.
Electric propulsion systems for small craft are generally designed and constructed from a number of
component parts many of which can be of proprietary origin and all of the electrical and control items
are interconnected by cables and operated as a system.
There are a significant number of electrical propulsion system architectures for small craft and the
main types are the following.
— DC sourced. The main power source is a propulsion battery which is either recharged from on-
board DC generators, or on-board AC generators/an AC shore supply through battery chargers. The
electric propulsion system(s) may be variable speed through a DC motor controller or AC through a
Variable Frequency Drive (VFD) or be fixed speed with a variable pitch propeller or other mechanical
means of providing thrust. The electric propulsion system may be electrically separate from other
electrical systems on board (e.g. be fully insulated via the motor controller, or be an AC IT system via
a VFD or motor starter). Or the electrical propulsion system may be integrated with the whole craft
DC electrical system using converters DC/DC, DC/AC to provide for different services/consumers.
— AC sourced. The main power source is AC generator(s) generally configured as TT, TN-C or TN-S.
The electric propulsion system(s) may be DC variable speed through a AC/DC converter and DC
motor controller, or AC through a VFD, or be fixed speed with a variable pitch propeller or other
mechanical means of providing thrust. The electric propulsion system may be DC fully insulated
system or be an AC IT system via a galvanically isolated VFD or via an isolating transformer. A DC
propulsion system(s) may be supported by propulsion battery.
— Also possible are hybrid systems similar to the types being introduced for road vehicles where the
source is an internal combustion engine providing, for example, energy to a relatively lightweight
energy storage system with power take-off via converters to propulsion motor(s) and other electrical
consumers.
It is essential that the electric propulsion system designer/installer be competent with all aspects
of the equipment included in the design of a particular system such that the component parts of the
propulsion system are integrated in a coherent and safe manner.
Current electrical standards for small craft of less than 24 m LH are the following:
a) ISO 10133 which is limited to recommendation for the design, construction and installation of
direct current systems that operate at a voltage of DC 50 V or less; and
b) ISO 13297 which is limited to single phase alternating current electrical systems less than AC
250 V.
Neither of these standards includes requirements for electrical propulsion systems.
c) IEC 60092-507 is applicable to small craft up to 50 m/500 GT and includes requirements for three-
phase systems not exceeding AC 500 V and single-phase systems not exceeding AC 250 V and for
DC systems and sub-systems not exceeding DC 50 V nominal, and includes a section on electric
propulsion systems.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
Electrical propulsion systems are becoming more common in recreational craft and other small craft
and propulsion system voltages of up to AC 1 000 V and DC 1 500 V are possible together with variable
speed drives operating at frequencies which differ from 50/60 Hz or DC.
Electric propulsion systems for small craft are generally designed and constructed from a number of
component parts many of which can be of proprietary origin and all of the electrical and control items
are interconnected by cables and operated as a system.
There are a significant number of electrical propulsion system architectures for small craft and the
main types are the following.
— DC sourced. The main power source is a propulsion battery which is either recharged from on-
board DC generators, or on-board AC generators/an AC shore supply through battery chargers. The
electric propulsion system(s) may be variable speed through a DC motor controller or AC through a
Variable Frequency Drive (VFD) or be fixed speed with a variable pitch propeller or other mechanical
means of providing thrust. The electric propulsion system may be electrically separate from other
electrical systems on board (e.g. be fully insulated via the motor controller, or be an AC IT system via
a VFD or motor starter). Or the electrical propulsion system may be integrated with the whole craft
DC electrical system using converters DC/DC, DC/AC to provide for different services/consumers.
— AC sourced. The main power source is AC generator(s) generally configured as TT, TN-C or TN-S.
The electric propulsion system(s) may be DC variable speed through a AC/DC converter and DC
motor controller, or AC through a VFD, or be fixed speed with a variable pitch propeller or other
mechanical means of providing thrust. The electric propulsion system may be DC fully insulated
system or be an AC IT system via a galvanically isolated VFD or via an isolating transformer. A DC
propulsion system(s) may be supported by propulsion battery.
— Also possible are hybrid systems similar to the types being introduced for road vehicles where the
source is an internal combustion engine providing, for example, energy to a relatively lightweight
energy storage system with power take-off via converters to propulsion motor(s) and other electrical
consumers.
It is essential that the electric propulsion system designer/installer be competent with all aspects
of the equipment included in the design of a particular system such that the component parts of the
propulsion system are integrated in a coherent and safe manner.
Current electrical standards for small craft of less than 24 m LH are the following:
a) ISO 10133 which is limited to recommendation for the design, construction and installation of
direct current systems that operate at a voltage of DC 50 V or less; and
b) ISO 13297 which is limited to single phase alternating current electrical systems less than AC 250 V.
Neither of these standards includes requirements for electrical propulsion systems.
c) IEC 60092-507 is applicable to small craft up to 50 m/500 GT and includes requirements for three-
phase systems not exceeding AC 500 V and single-phase systems not exceeding AC 250 V and for
DC systems and sub-systems not exceeding DC 50 V nominal, and includes a section on electric
propulsion systems.
