Anchor Chain Inspection Steps
Proper anchor chain maintenance starts with a thorough inspection. You need to check every part of your anchor system to ensure safety and reliability before every voyage. Follow these steps to make sure your anchor, chain, and anchor rode are in top condition.
Visual Check
Start by laying out the entire chain on a flat surface. Use a flashlight and inspection mirror to see every link. Look for obvious signs of damage or wear. Marine safety organizations recommend the following process:
Range out the chain cables on the dock floor.
Visually inspect the cables for wear and damage.
Measure the link diameter with calipers or micrometers.
Note:
You should inspect 100% of the chain for missing studs, bent links, corrosion, sharp gouges, loose studs, cracks, and wear.
Check for these common visual indicators:
Rust spots
Pitting (small holes)
Cracks
Bent or misshapen links
Worn shackles
If you find any of these issues, mark the affected areas for further assessment. Powerful Machinery’s studless anchor chain makes this process easier because its flexible design allows you to lay out and inspect each link without difficulty.
Corrosion and Wear
Saltwater and harsh marine environments can cause corrosion and wear on your anchor chain. Examine each link for rust and thinning. Pay close attention to areas that look dull or have a reddish-brown color. These spots often signal corrosion.
Rust and corrosion weaken the metal and can shorten the life of your anchor chain.
Worn links appear thinner and may feel rough to the touch.
Bowed or bent links show that the chain has experienced mechanical stress.
You should also check for abrasion caused by dragging the anchor over rocks or sand. If you use both galvanized and stainless steel chains together, be aware that mixing these metals can increase corrosion rates.
In saltwater, the zinc coating on galvanized steel may corrode faster when in contact with stainless steel. Powerful Machinery’s studless anchor chain comes in galvanized and AISI 316 stainless steel options, both designed for high corrosion resistance and certified by RINA and BV for marine use.
Link and Shackle Assessment
After checking for corrosion and wear, focus on the links and shackles. Use calipers to measure the diameter of each link. Compare your measurements to the original specifications. If you notice any stretch or elongation, this could mean the chain has been overloaded.
Any amount of stretch is a sign of overloading. Remove the chain from service if you see this.
If elongation reaches 20% of the chain’s original size, you must replace the chain.
Always check the manufacturer’s guidelines for acceptable elongation limits.
Inspect shackles for wear, cracks, or deformation. Worn shackles can fail under load and put your vessel at risk. Replace any shackles that show signs of damage. Powerful Machinery’s anchor chains and accessories meet strict international standards, so you can trust their performance and safety.
Tip:
Regular inspection of your anchor, chain, and anchor rode helps you catch problems early and keeps your vessel secure.
Cleaning and Maintenance
Keeping your anchor chain in top condition requires regular cleaning and proper care. This section guides you through the essential steps for effective anchor chain maintenance, helping you protect your anchor system and extend the life of your equipment.
Freshwater Rinse
After every use, rinse your anchor chain thoroughly with fresh water. Salt and marine debris left on the chain can cause rust and weaken the metal over time. Freshwater rinsing removes salt crystals and dirt that stick to the links.
Always rinse the chain immediately after weighing anchor. Let the chain dry in an open anchor locker to prevent moisture buildup.
Tip:
Freshwater rinsing is one of the simplest and most effective ways to prevent corrosion. Make it a habit after every trip.
Removing Debris
Marine growth, like barnacles, mussels, and algae, can attach to your anchor chain. These organisms add weight and can damage the chain’s surface. Use a stiff brush or a cleaning tool with flexible arms made from soft polyurethane. This material cleans tough marine growth without scratching coated surfaces.
For stubborn debris, scrub with a metal brush or use a diluted acidic cleaning agent. Mix one part acid with three parts fresh water to create a safe solution for removing rust and marine debris. Always rinse the chain with fresh water after using any cleaning agent.
