Download your copy of the ABS Guide for Use of Supercapacitors in the Marine and Offshore Industries.
Hybrid electric power applications are increasing in the marine and offshore industries. ABS recognizes the application of supercapacitor technology in support of the hybrid initiatives and its benefits for improving energy efficiency of the onboard power plant. Supercapacitors, as a commercialized energy storage device, exhibit beneficial characteristics such as high power density, a fast charging/discharging process, no thermal runaway characteristics, and wide operating-temperature range. The operating environment typical in the marine and offshore industries may differ from those considered when a supercapacitor system was originally designed, and so necessitates a review of the environmental and operational aspects prior to adoption.
ABS has produced a Guide to provide requirements and reference standards to facilitate effective installation and operation of on-board supercapacitor systems. The purpose of this Guide is to establish safety guidelines for owners, operators, shipyard builders, designers, and manufacturers. The supercapacitors covered by in the Guide are also referred as Electrical Double Layer Capacitors (EDLC), Electrochemical Capacitors, or Ultracapacitors. Requirements applicable to conventional electrolytic capacitors used for power factor correction or harmonic filtering are contained in Part 4 of the ABS Rules for Building and Classing Steel Vessels.
Supercapacitor technology is continuously evolving with respect to materials and design. Alternative arrangements or new supercapacitor technologies may be considered to meet the overall safety standards of the Guide and the ABS Rules.
