Corrosion in Container Terminals and Ports

Corrosion in Container Terminals and Ports

Introduction: Why Corrosion Is a Critical Threat to Ports

Corrosion is a silent yet formidable adversary in the maritime industry. At container terminals and ports—where metal infrastructure dominates and salt-laden air is constant—corrosion can cause serious structural damage, safety hazards, and financial losses. From dockside cranes and quay walls to pipelines and storage tanks, no metallic component is immune. As trade volumes rise and equipment ages, combating corrosion becomes not just a maintenance task but a strategic imperative for port operators worldwide.


Understanding the Root of the Problem

What Causes Corrosion in Ports?

Corrosion is the electrochemical reaction between a metal and its surrounding environment, leading to degradation. In container ports, several factors exacerbate this process:

  • Saltwater exposure: Salt ions accelerate oxidation, especially on exposed steel.

  • Humidity and condensation: Coastal climates provide consistent moisture, triggering corrosion.

  • Pollution and acid rain: Industrial emissions mix with moisture to form acids that attack metal surfaces.

  • Mechanical wear: Heavy machinery causes micro-abrasions, creating entry points for corrosion.

  • Galvanic reactions: When dissimilar metals are in contact, corrosion of the less noble metal accelerates.

As a result, even routine port operations contribute to accelerated material decay.

High-Risk Areas in Ports

Ports are sprawling complexes with many vulnerable zones. Consequently, corrosion doesn’t occur uniformly but targets specific high-risk areas:

  • Quay cranes and RTGs (Rubber Tyred Gantry Cranes): These are continuously exposed to salty air and heavy mechanical loads.

  • Steel fenders and bollards: Constant vessel contact and splash zones increase corrosion rates.

  • Underground and subsea pipelines: These components suffer both internal and external corrosion.

  • Electrical panels and junction boxes: Moisture ingress can cause rust and short circuits.

  • Storage tanks and fuel lines: Standing water and acidic contaminants corrode these systems from within.


The Real-World Consequences of Corrosion

1. Safety Hazards

Corrosion weakens structural integrity over time. For instance, cracked welds, rusted joints, and brittle beams pose serious risks to operators and port workers. Therefore, early detection is vital.

2. Operational Downtime

Damaged equipment leads to unexpected breakdowns. Consequently, when cranes, conveyors, or hoists fail, entire terminal operations may halt—disrupting supply chains and productivity.

3. Increased Maintenance Costs

As corrosion progresses, costs rise dramatically. While surface rust may be inexpensive to treat, advanced structural degradation requires costly overhauls or replacements.

4. Environmental and Compliance Risks

Leaking pipelines or corroded tanks can release pollutants, thus breaching environmental regulations. Moreover, failure to address these risks often results in severe penalties.

5. Reduced Asset Lifespan

Without adequate corrosion control, infrastructure reaches its end-of-life prematurely. This not only undermines investment but also triggers early capital expenditure.


Industry-Proven Solutions to Combat Corrosion

Fortunately, corrosion can be managed. An integrated approach using modern coatings, smarter materials, and digital tools significantly reduces its impact.


1. Protective Coatings and Surface Treatments

Epoxy and Polyurethane Coatings

These coatings act as moisture-resistant barriers on steel surfaces. Typically used on cranes, tanks, and handrails, they delay rust formation.

Thermal Spray Coatings

By applying zinc or aluminium via thermal spray, ports create a sacrificial layer that corrodes in place of the base metal. As a result, equipment life is extended.

Cathodic Protection Systems

Cathodic protection, either through sacrificial anodes or impressed current, redirects electrochemical corrosion away from vulnerable structures.


2. Material Selection and Design Improvements

Use of Corrosion-Resistant Alloys

Instead of carbon steel, ports can use stainless steel, duplex steel, or even composites, which are inherently more corrosion-resistant.

Smart Engineering Designs

Proper design plays a major role. For example, sloped surfaces minimize water pooling, while sealed joints prevent moisture ingress.


3. Environmental Control Systems

Dehumidifiers in Enclosed Areas

Humidity is a major driver of corrosion. Therefore, installing dehumidifiers in cabinets and control rooms reduces condensation risks.

Drainage and Water Management

Standing water accelerates corrosion. Thus, ports must maintain efficient drainage around dock structures, walkways, and storage yards.


4. Routine Inspections and Predictive Maintenance

Visual and Ultrasonic Testing

Routine inspections, including ultrasonic testing, help detect corrosion before visible damage occurs.

Corrosion Mapping and Digital Twins

Many advanced ports now use 3D models and digital twins. These tools track corrosion progression and alert maintenance teams in real time.

Predictive Maintenance Software

Artificial intelligence is increasingly used to predict when and where corrosion will occur. Consequently, operators can plan repairs more effectively.


5. Retrofitting and Refurbishing Aging Infrastructure

Although full replacement is costly, retrofitting offers a practical alternative:

  • Recoating and sandblasting metal surfaces

  • Replacing fasteners with non-metallic alternatives

  • Installing new cathodic protection on old systems

  • Using composite repair wraps to reinforce corroded pipes

As a result, aging assets can be extended for years.


6. Partnering with Corrosion Experts and OEMs

Instead of tackling corrosion alone, many ports partner with industry leaders. For example:

  • Hempel and Jotun: Leaders in marine-grade protective coatings

  • Kalmar and Liebherr: OEMs offering anti-corrosion packages on port cranes

  • Corrosion service providers: Firms that provide audits, retrofits, and coating services

Collaboration ensures optimal protection strategies tailored to specific port conditions.

Keeping an Eye on Your Equipment

August through October is known as the windy season in South Africa. During this time, we have all witnessed the windstorms sweeping across the country, bringing with them the much-anticipated rain and the onset of summer.

When the weather turns unpredictable, companies in the engineering, agriculture, and mining sectors must stay vigilant about their equipment. Notably, a breakdown or potential injury on duty concerns everyone involved. Therefore, regularly checking all equipment is crucial to ensure no potential dangers are looming.

Neglecting the operational aspects of a plant leads to dangerous errors. Consequently, routine safety checks are vital to the success of any plant and the safety of its employees, ensuring that everything runs smoothly.

Moreover, mining equipment endures significant stress due to the workload it handles, which causes wear and tear on all the components that keep the plant operational. Thus, a strict maintenance schedule is essential to prevent downtime caused by equipment failure.

Furthermore, strong winds can blow dust and sand into a plant, damaging intricate parts of the operation that are not always visible to the naked eye.

To help you maintain your industrial equipment effectively, here are a few tips:

Five Tips for Successfully Maintaining Your Mining Equipment

First, Keep Machinery Lubricated at All Times
Without proper lubrication, any machine will eventually fail. Indeed, lubrication is as critical as the moving parts themselves. Regular and correct lubrication reduces excess friction, which in turn extends the machine’s lifespan and prevents premature deterioration. However, over-lubrication can cause issues such as energy loss, damage to seals, and an excessive buildup of grease. Therefore, always use the appropriate type of lubrication for each machine to avoid breakdowns.

Second, Clean Heavy Machinery Thoroughly
Heavy machinery has special seals to protect its intricate parts. If dirt and grime infiltrate these seals, they can cause catastrophic damage and loss, often unnoticed by the untrained eye. Therefore, immediately replace broken or torn seals, and keep breathers free from debris. Additionally, change filters as soon as they become dirty or clogged. Covering or storing machinery indoors during heavy winds or rain also prevents dirt and grime from causing trouble.

Third, Keep Up with Regular Maintenance
Inspecting or repairing only when something goes wrong isn’t enough to keep heavy machinery in top condition. For this reason, establish a regular inspection plan, and take detailed notes on any inspections performed. Regularly check gaskets, seals, belts, and pulleys for proper alignment. Moreover, continually monitor moving parts, such as gears, for wear and tear or damage, and apply proper lubrication to keep them functioning optimally.

Fourth, Monitor Wear and Tear
During normal operations, you may notice wear and tear on parts or machines. Addressing these signs promptly is crucial as they may indicate more severe problems, especially with braking systems. For instance, common signs of wear and tear include heat, vibration, and changes in belt shape. Overheating often results from improper lubrication, and vibration may signal misaligned gears or belts.

Finally, Train Operators Thoroughly
One of the most effective ways to keep heavy machinery operational is through thorough staff training. New employees should undergo intensive training to ensure they understand how everything works and know what to look for in case of a problem. Meanwhile, current employees should attend refresher courses and receive inductions on any new machinery or parts. Consequently, regularly scheduled training courses ensure that all operators are equipped to handle machinery correctly, reducing the risk of downtime or costly accidents.

If you want to extend the lifespan of your heavy machinery, the tips above will certainly guide you in the right direction.
