ICCP Crawler: Keeping Vessels out of Drydock
Maintaining impressed current cathodic protection (ICCP) is essential for protecting steel hulls, but changing electrodes inside cofferdams has traditionally meant diver callouts, extended timelines, and in some cases, a costly trip to drydock. Each unplanned dock visit can add millions to the maintenance bill.
After extensive research and development, our team designed the ICCP Crawler to deliver controlled, high-quality electrode change-outs directly from the hull – eliminating diver dependency and keeping vessels operational.
About the ICCP Crawler
The ICCP Crawler is a magnetically adhered, remotely operated system purpose-built for cofferdam work. It combines three HD cameras for continuous visual oversight, a magnetic capture cup to lock onto electrodes, and a compact robotic arm that performs removal and reinsertion with accuracy and repeatability. Operators control the entire sequence from deck using our Juicebox controller, retaining clear visuals at every step.
The Challenge
Cofferdam maintenance is never straightforward. Geometry is tight, surfaces are fouled, and traditional methods often run into visibility delays and unpredictable timelines. Mobilising divers and equipment is not only slow but can also quickly escalate costs. For vessel operators, that often means a choice between absorbing downtime offshore or scheduling expensive drydock time.
The Solution
The ICCP Crawler changes that equation. Launched from deck, it drives securely along the hull to the cofferdam, maintains adhesion on varied coatings, and delivers a precise electrode change-out under full operator control. With clear visuals from three camera angles and a magnetic capture system that eliminates drops, the process is auditable, efficient, and predictable. The result: fewer delays, reduced reliance on external teams, and a workflow that helps avoid unnecessary drydock visits.

Operator-First Design
We built the workflow around a clear storyboard all the way from setup to recovery, and engineered to it: cameras for clean sightlines, a compact arm sized to the cofferdam envelope, tracks/adhesion optimised for multiple coating types, and an interface that mirrors the sequence in Juicebox so each step feels natural and repeatable. That means faster training, more consistent outcomes, and significant cost savings over the life of the vessel.
