Stud link anchor chains are a type of heavy-duty chain commonly used for anchoring and mooring vessels. They have a central stud in each link that helps to prevent kinking, deformation, and fouling. These chains are known for their strength and are often preferred for large vessels and applications where significant loads are involved.
The dual shank anchor features two parallel shanks that work together to embed and hold in various seabed conditions. This design provides higher holding power than traditional anchors, especially in soft ground and mud, and is commonly used in aquaculture and swing moorings.
Mooring shackles are manufactured with alloy steel by following ISO9001 Quality Control System. With our years know-how on forging, heat treatment and hot dip galvanized, it is ensured the mooring shackle avoid any Hydrogen Embrittle-ment and offer a longer fatigue life of safe performance compared to EN13889 requirement and safety.
Mooring connection plates are manufactured using alloy grade material and followed by full heat treatment process.The durability ensures that the plates can withstand exposure to saltwater, reducing maintenance needs and extending the lifespan of the aquaculture setup.
Sinostar Marine is a manufacturer of AM2/AM3 stud link anchor chains.Can provide LR, DNV, CCS, ABS, BV and other classification society certification.

H-shape design
The main body of the shackle is in ‘H’ shape structure, the ring eyes on both sides are symmetrically distributed, and the middle beam provides high-strength support, which makes the overall force uniform, and the tensile and shear resistance is excellent.
The inner wall of the ring eye is smooth, which reduces the wear and tear of the rope or chain and prolongs the service life.
High strength material
Usually made of alloy steel (e.g. 40Cr, 42CrMo) or high-strength stainless steel (e.g. 316L), the surface is heat-treated or zinc-plated, sprayed, etc., to enhance the abrasion and corrosion resistance.
Safety locking mechanism
Equipped with high-strength bolts or pins to ensure a firm connection and prevent accidental dislodgement.
Suitable for offshore platforms, ship mooring, deep-sea operations, etc., to withstand high salt spray, high humidity environment.
Energy field
In the oil, gas, electric power and other industries, it is used for lifting drilling equipment, pipelines, transformers and so on.
Material Alloy steel (40Cr), stainless steel (316L)
Surface treatment Heat treatment, zinc plating, spraying.
Rated load Depending on the model, the load range is from a few tonnes to hundreds of tonnes.
Safety factor Usually 4:1 or 6:1 (i.e. breaking load is 4 or 6 times the rated load).
Operating temperature -40°C to +200°C (some models can withstand higher temperatures)
Certification standards Comply with international standards such as DIN, EN, ISO, etc., and some models have been certified by classification societies such as CCS and ABS.
Selection and matching
Select the appropriate model according to the actual load, overloading is strictly prohibited.
Make sure the rated load of the shackle is greater than or equal to 1.5 times of the actual working load (considering the safety factor).
Regular inspection
Check the surface of the buckles for cracks, deformation, wear and other defects before use.
Conduct regular non-destructive testing (such as magnetic particle flaw detection, ultrasonic testing) to ensure that there is no internal damage.
Correct installation
Ensure that the rope or chain passes through the eye of the ring correctly and avoid twisting or knotting.
When locking bolts or pins, tighten them according to the specified torque to prevent loosening.
Environmental adaptability
In corrosive environments, give preference to buckles made of stainless steel or galvanised.
Avoid using in high temperature or low temperature extreme environment beyond the range of material resistance.
High strength and light weight: H-shape design optimises force and reduces weight.
Strong durability: high-quality materials and surface treatment, adapt to harsh working conditions.
High safety: strict compliance with international standards, equipped with safety locking device.
Wide range of applications: covering marine, energy and other fields.
