After two anchor strike incidents, New York Power Authority implemented the Guardian solution to protect power cables across Long Island Sound.

Download the Case Study


  • New York Power Authority operates four Long Island Sound Submarine cables which deliver critical power to Long Island.
  • They experienced anchor strikes on their cables in 2004 and 2014.
  • Repairs and clean up spanned several months at a cost of tens of millions of dollars.


  • Guardian electronically marks the cable area using virtual AIS buoys for vessels to see on their electronic navigation systems.
  • Vessel movements and behavior are continually processed to determine if they are potentially anchoring too close to the cable field.
  • In case of a potential risk, alert messages are sent proactively directly to the vessel’s on-board electronic display and New York Power Authority network operations center.


  • Enhanced protection by Vesper Marine helps eliminate anchor strikes and the resulting environmental impact.
