Find Trusted Cathodic Protection Inspection Providers with Records Marine

Corrosion is a constant threat in the marine environment, especially beneath the waterline. Cathodic protection inspection plays a vital role in keeping hulls, propellers, and other submerged structures in top condition. Without regular checks, even well-installed systems can fail silently - leading to costly damage or loss of structural integrity.

At Records Marine, we help you connect with verified experts who specialize in underwater inspection services, including cathodic protection surveys. Whether you're maintaining a fleet or preparing for drydock, our platform makes it easier to find certified professionals who know how to safeguard your marine assets. Routine inspections don’t just prevent corrosion - they extend the lifespan of your equipment and help you stay compliant with class requirements.

What Is Cathodic Protection and Why Is Inspection Essential?

Cathodic protection is a method used to guard submerged metal parts - like hulls, propellers, and rudders - against corrosion in harsh marine environments. By turning these components into the cathode of an electrochemical cell, the system helps prevent metal loss and structural weakening over time.

But installation alone isn’t enough. Regular inspection plays a critical role in marine corrosion prevention, ensuring the system is still working as designed. Ship hull inspections verify anode condition, detect potential coating failures, and help avoid premature wear, costly repairs, or even compliance issues during class surveys.

Types of Cathodic Protection Systems on Ships

There are two primary cathodic protection systems used on vessels: sacrificial anode systems and impressed current cathodic protection (ICCP).

Sacrificial anodes are made from metals like zinc or aluminium, which corrode instead of the ship’s structure. These are simple, passive systems that require periodic replacement.

ICCP systems use an external power source and inert anodes to deliver controlled current to protected areas. They're more complex but offer precise control and longer service life.

Inspection methods differ: sacrificial systems are checked for anode wear, while ICCP inspections also involve monitoring voltage levels and system calibration.

What Does a Cathodic Protection Inspection Include?

A cathodic protection inspection, often called a survey, checks how well your corrosion protection is holding up. It usually starts with a close-up look at all the anodes. Inspectors check for signs of heavy wear, breakage, or anything that might reduce performance.

Next, they measure electrical potential using reference cells placed near the hull. This shows whether the system is working within the expected range. They’ll also assess the overall condition of the system - including mounting points, cable connections, and nearby coatings.

Findings are recorded in a detailed report with photos, readings, and notes to help with future maintenance. Most inspections happen during scheduled dry docks or underwater, using trained divers or ROVs depending on the setup.

How to Choose a Reliable Cathodic Protection Inspection Provider

Not all cathodic protection inspection companies follow the same standards, and when vessel safety is on the line, cutting corners isn’t an option. Choosing the right team makes all the difference in getting accurate results and actionable insights.

Here are a few key things to look for when selecting a provider of marine inspection services:

  • Certification & Qualifications - Always verify diver certifications, inspection licenses, and company credentials.
  • Industry Experience - A proven track record in ship hull surveys and underwater services is a strong indicator of reliability.
  • Modern Equipment - Up-to-date tools like calibrated reference cells, ROVs, and high-resolution imaging improve survey accuracy.
  • Clear Reporting Standards - Professional companies provide structured reports with readings, photos, and honest assessments.
  • Knowledge of Local Rules - Especially for vessels operating internationally, providers should understand flag state and port-specific inspection standards.

Records Marine simplifies the search for reliable cathodic protection inspection companies by offering a directory of verified providers backed by real maritime experience. 

Routine inspections are key to marine asset management. They help detect early signs of corrosion, extend the lifespan of hulls and fittings, and reduce repair costs. Regular underwater maintenance also supports regulatory compliance and ensures vessel safety.
