(www.MaritimeCyprus.com)Â ABS has published the ABS Guide to Wind-Assisted Propulsion System Installation, providing class safety standards when installing wind-assisted systems.
The Guide is applicable to two leading wind-assisted propulsion technologies: Flettner rotors and wing sails, including both rigid and soft sails.
IMO has recognized wind assisted propulsion technology and its potential impact on energy savings and has included the effects of wind propulsion into the Energy Efficiency Design Index (EEDI) calculation in
MEPC.1/Circ. 815, in which wind assisted propulsion technology is considered a method of reducing main engine power requirements.
This Guide is applicable to two modern wind assisted propulsion technologies: Flettner rotors and wing sails (including rigid sails and soft sails). These technologies use the wind thrust generation and automatic control system to optimize thrust force generation based on wind conditions. These systems differentiate themselves from conventional sails in that they possess greater efficiency, smaller windage area, and automatic control systems.
These technologies are continuously evolving. Alternative arrangements, designs and technologies may be acceptable on a case-by-case basis, provided they can be demonstrated, through either satisfactory service experience or a systematic evaluation based on sound engineering principles, to meet the overall requirements of this Guide.
