VIEWPOINT
Breakthrough in Advanced Technology
Implementation and Risk Mitigation in
Electrical Ships and Offshore Platforms
By Yuri Khersonsky
T THE BEGINNING OF THIS
century, the IEEE designated electric ship technologies as one of the ten emerging
technological challenges of 21st century and started its Electrical Ship
Technologies Initiative. The IEEE
established the Electric Ship Technologies Symposium (ESTS) and new
IEEE standards working groups to
develop new standards for ships.
Almost simultaneously, the U.S.
Office of Naval Research (ONR) decided to create the Electrical Ships
Research and Development Consortium. The consortium is made up of
seven universities and focuses on the
research and development activities
related to electric ships. Additionally,
the consortium aims to address the
shortage of electric power engineers
by providing educational opportunities
for students in state-of-the-art experimental facilities. These combined
efforts brought together the resources
of the shipbuilding industry community, leading electric power research
institutions and the collective practical
experience of many generations of
professional electrical engineers in the
IEEE. They also accelerated implementation of new technologies and analytical tools and helped mitigate the
challenges of electrical ship technologies. For example, at the opening of

the first ESTS in 2005, the slide shown
in Figure 1 was presented.
Being an active participant in ESTS
2005, the ONR decided to support IEEE
standards working group activities. Generous support from additional industrial
partners helped to develop the following IEEE and International Electrotechnical Commission (IEC) standards:
IEEE Standard 1566-2005: Standard

* Flush Arcs Absorber
* Grounding Rod Into the Water
* Water Heater for Five Oceans
* Barge for Power Electronics Filters

The ONR also provided funds to
industrial partners and the Electric
Ship Research and Development
Consortium for research in stability
analysis MVdc power systems, fault
detection, solid-state protection, arcfault detection, and grounding.
The most significant advances
made in shipboard solid-state protection, zonal power distribution (a.k.a.
microgrids), galvanic isolation, and
MVdc shipboard power systems are
described in issues of IEEE Electrification
Magazine [1]-[3]. All of the electric ship
challenges in Figure 1 are addressed in
IEEE Electrification Magazine and IEEE
standards 1662-2008 and 1709-2010;
however, they are not yet solved.
Detailed reviews of what is important
in the latest electric ship standards and
Italian contributions are in [5] and [6].
