Ideally the last two anodes of the string will hang in the mud on bottom; this increases the the current efficiency.

This custom clamp is designed with several I-Clips™ (white) which eliminate the possibility for crevice corrosion around the clamp.
The clamp on stand-off can be used for vertical members as well.
Entire structures in the shallows of the Gulf of Mexico have been retroffited using the RetroLink system.
Clamp-on stand-offs have to be selected before hand for specific jobs - sizes are available from 6 in to 36 in.
Continuity is maintained by the leader wire welded to the stand-off.
With anodes resting on bottom the string is quite stable through the splash zone.
Once the stand-off has been welded, and the anode string has been attached to the leader assembly, the boat just backs away.
The average design life for a RetroLink system is 3-5 years.
After the RetroLink is installed, the offshore personnel responsible must conduct continuity testing.

I-Clip is made from our popular I-Rod material, the integral part fo all of our anti-corrosion pipe support products.
The clamp is very durable; ideal for rough seas in the splash zone.
This photo is from a large Gulf of Mexico cathodic protection retrofit conducted in 2009.
The RetroLink is shipped bundled together, it can be cut to length in the field for any water depth up to 85 ft..

Here a RetroLink system is being installed on a jetty struvcture in the Bahamas; only a small vessel is required.
Weld-on standoffs and RetroLinks can be kept on small corrosion inspection vessels, in case low CP readings are found.
