PROACTIVE AUTOMATED PROTECTION
24/7 automated alerting solution to prevent vessel anchors damaging submarine cables and pipes
Preventable Anchor Damage
Physical protection is not enough
It’s expensive, doesn’t always work and is often not feasible.
Physical protection should be utilised where possible. Armored enclosures, burying cables and pipes and encasing them in concrete or rocks will reduce the liklihood of damage from anchor strikes.
However, these measures are often not feasible. The expense, regulatory barriers and often logistical impossibilities result in large lengths of submarine assets going completely unprotected.
They aren’t always effective. Despite being buried 12 feet under the seabed, Anchor Strikes cost the New York Power Authority tens of millions in repair costs.
An independent report commissioned by Enbridge advised that Guardian:protect would reduce the likelihood of an anchor strike by 88.4%.

Why DO Anchor Strikes Still Happen?
1. Cables and pipes are difficult to physically protect. Large anchors can penetrate armor, damage cables buried under the sea floor and impact cables in deep water. Large vessels drag cables and pipes – so don’t even need to drop anchor directly onto them to cause damage.
2. Human error by the vessel crew is the fundamental problem. A decision is made to drop anchor in a location that should not be anchored. A decision is made to not check anchor stowage over a cabled area. Mitigating human error has a significant impact
Mitigating human error is the key to protection.
“Yates misread the navigation chart”
– HONORABLE PAUL A. CROTTY, United States District Judge
The captain of the barge causing tens of millions in damages to NYPA’s submarine cable under Long Island Sound misread the dotted lines in the navigational charts as indicating where the cables were, instead of the space in between them.
