How To Choose Marine Chains
When choosing marine chains, consider the following factors:
1. Chain grade: Chains are graded based on their strength, durability, and resistance to corrosion. Choose chains with high-grade alloys that offer greater load capabilities and better resistance to saltwater corrosion.
2. Size: Choose a chain size that is appropriate for the intended purpose and usage. Consider the breaking strength, weight, and safe working load of the chain based on the size and weight of the vessel or marine structure.
3. Material: Choose chains made from corrosion-resistant materials such as stainless steel or galvanized marine-grade steel.
4. Chain design and finish: Determine the chain design and finish based on the intended use. For example, coatings such as hot-dip galvanizing or electroplating can provide added protection against corrosion.
5. Chain length: Determine the length of the chain based on the depth of the water and the depth of the anchoring point.
6. Quality and certification: Choose chains that meet international quality and safety standards such as those set by the American Bureau of Shipping (ABS) or Det Norske Veritas Germanischer Lloyd (DNV GL).
7. Cost: Consider the cost of the chains based on their quality and features, and select the option that provides the best value for money for your needs.
Overall, it is important to choose high-quality marine chains that are appropriate for the intended use and meet safety and quality standards, providing reliable and safe mooring for your vessel or marine structure.
