MARITIME – ANCHORING & MOORING CALCULATOR
Anchor Chain Weight Deck
A precise tool.
What is the Anchor Chain Weight Deck & How does it work?
The weight of an anchor chain on deck is a critical factor in vessel stability and deck load planning. Engineers must account for the total mass of the chain, which depends on its length, material density, and the number of chain legs deployed. Chain weight is typically expressed as a linear weight (kilograms per metre) provided by the manufacturer. Multiplying this linear weight by the deployed length of each chain gives the weight per chain, and summing across all chains yields the total deck load. Accurate calculation ensures compliance with safety regulations and helps prevent over‑loading of deck structures, which could lead to structural fatigue or failure.
W = L \times w \times n
W = total weight (kg)

Frequently Asked Questions
How do I calculate the total weight of anchor chains on deck?
Multiply the linear weight of each chain by its deployed length, then sum across all chains.
What factors affect the weight of an anchor chain?
The weight depends on the chain’s length, material density, and number of legs deployed.
How important is considering anchor chain weight for vessel stability?
It’s crucial for ensuring the vessel remains stable and that deck loads are properly managed.
What should I do if I need to change the length of my anchor chains?
Recalculate the total weight using the new lengths and adjust your deck load planning accordingly.
Can you provide an example calculation for anchor chain weight?
Sure, multiply the linear weight (e.g., 5 kg/m) by the length of the chain (e.g., 100 m) to get 500 kg per chain.
How does the material density of the chain affect its weight?
A denser material will result in a higher linear weight, thus increasing the total deck load.
What should I consider when planning for multiple anchor chains on deck?
Account for the weight of each chain separately and sum them to get the total deck load.
