Anchor Chains: A Crucial Component for Safe and Secure Anchoring

As the oil and gas industry continues to grow, the importance of safe and secure anchoring becomes increasingly important. Anchor chains, also known as amarra de ancoragem in Portuguese, play a crucial role in ensuring that offshore structures remain stable and secure in harsh sea conditions.

Anchor chains are used to connect an offshore structure, such as an oil rig or a floating production storage and offloading vessel (FPSO), to the seabed. They are designed to withstand the forces of wind, waves, and currents, ensuring that the structure remains in place and does not drift away.

Subsea pipelines and umbilicals are also anchored using anchor chains, providing stability and preventing damage from external forces.

The Importance of Anchor Chains

Anchor chains are a critical component of offshore structures, providing stability and security in harsh sea conditions. They are designed to withstand extreme loads, ensuring that the structure remains in place even in the face of strong winds, waves, and currents.

Without anchor chains, offshore structures would be at risk of drifting away or being damaged by external forces. This could lead to significant safety risks for personnel on board, as well as environmental damage from spills or leaks.

Design and Construction of Anchor Chains

Anchor chains are typically made from high-strength steel, with each link designed to withstand extreme loads. The links are connected using shackles or other fittings, creating a continuous chain that can be adjusted to suit the specific requirements of the offshore structure.

The design and construction of anchor chains is subject to strict regulations and standards, ensuring that they are fit for purpose and can withstand the forces they will be subjected to.

Maintenance and Inspection

Regular maintenance and inspection of anchor chains is essential to ensure their continued effectiveness. Corrosion, wear, and other forms of damage can compromise the strength of the chain, increasing the risk of failure.

Inspection techniques such as visual inspection, magnetic particle inspection, and ultrasonic testing are used to detect any signs of damage or wear. If any issues are identified, repairs or replacement may be necessary to ensure the continued safety and effectiveness of the anchor chain.


1. How often should anchor chains be inspected?

Anchor chains should be inspected regularly according to industry standards and regulations. This typically involves visual inspection every six months and more detailed inspections every three years.

2. Can anchor chains be repaired if they are damaged?

Yes, if damage is identified during inspection, repairs may be possible depending on the extent of the damage. However, if the damage is too severe, replacement may be necessary.

3. What happens if an anchor chain fails?

If an anchor chain fails, it can lead to significant safety risks for personnel on board and environmental damage from spills or leaks. Regular inspection and maintenance can help prevent failures from occurring.
