Stud link anchor chains are vital components in the maritime and offshore industries, providing the essential connection between vessels and the seabed. These chains guarantee the security and stability of ships, rigs, and floating platforms, even under the most challenging sea conditions. Spain, with its rich maritime heritage and strategic geographic location, hosts some of the leading stud link anchor chain manufacturers and suppliers in Europe. This article delves into the top manufacturers and suppliers in Spain, exploring their products, manufacturing processes, certifications, and the unique advantages they offer to the global marine market.
A stud link anchor chain is a specialized type of heavy-duty chain used primarily for anchoring ships and marine structures. Unlike ordinary chains, stud link chains have a metal stud welded inside each link. This stud prevents the link from deforming under heavy loads, increases the chain's rigidity, and improves its overall strength and fatigue resistance. These properties make stud link anchor chains the preferred choice for large vessels and offshore installations.
The chains are typically manufactured from high-strength alloy steel, designed to withstand corrosive saltwater environments and mechanical stresses. Their robust construction ensures safety and reliability during anchoring operations, which are critical for vessel stability and maritime safety.
Stud link anchor chains play several crucial roles in maritime operations:
- Vessel Security: They anchor ships securely in harbors, offshore locations, or during adverse weather conditions, preventing drifting and potential accidents.
- Offshore Platform Stability: Floating oil rigs and wind farms rely on stud link chains for mooring and station-keeping.
- Durability in Harsh Environments: Their construction allows them to endure continuous exposure to saltwater, currents, and heavy mechanical loads.
- Operational Efficiency: Reliable anchor chains reduce downtime and maintenance costs, ensuring smooth maritime operations.
Spain's marine manufacturing sector includes several distinguished companies specializing in stud link anchor chains. These manufacturers combine advanced technology, skilled craftsmanship, and strict quality control to produce chains that meet international standards and customer expectations.
Founded in 1967, D. Koronakis S.A. is a family-owned business with decades of experience producing marine ropes, wire ropes, and stud link anchor chains. Their products cater to the shipping, offshore oil and gas, and drilling industries. The company emphasizes quality, durability, and compliance with international standards, making it a trusted name in Spain and abroad. They also provide technical support and customized solutions to meet specific client requirements.
Located in Mallorca, Links Marine is a leading supplier of certified stud link anchor chains ranging from small diameters of 12.5 mm to large sizes exceeding 100 mm. Their chains meet classification society requirements such as Lloyd's Register and ABS. Links Marine offers value-added services including re-galvanization to extend chain life, fast delivery, and comprehensive technical assistance. Their commitment to quality and customer satisfaction has earned them a strong reputation in the marine supply market.
CMP Anchor Chain operates from the strategic port of A Coruna, providing a wide range of high-strength stud link anchor chains. Their product portfolio includes chains from 12 mm up to 162 mm diameters, manufactured in various steel grades and surface finishes such as hot-dip galvanized and painted options. CMP focuses on delivering products that combine excellent corrosion resistance with mechanical strength, tailored for demanding marine applications. Their adherence to international certification standards ensures global acceptance and reliability.
Beyond these major manufacturers, Spain is home to numerous marine equipment suppliers and service companies offering stud link anchor chains as part of their product range. These companies often provide OEM manufacturing, installation services, and after-sales support, catering to foreign marine brands and shipowners. Their extensive experience in marine logistics and supply chain management ensures timely delivery and technical assistance.
Stud link anchor chains must adhere to stringent technical specifications to guarantee safety and performance:
- Material Composition: High-strength alloy steels such as K3, K4, and K5 are commonly used. Stainless steel variants are available for enhanced corrosion resistance.
- Diameter Range: Chains typically range from 12.5 mm to 162 mm in diameter, selected based on vessel size and anchoring requirements.
- Grade Classification: U1, U2, and U3 grades are standard, with U3 offering the highest tensile strength for heavy-duty applications.
- Surface Treatment: Hot-dip galvanizing is the most common coating, providing a zinc layer that protects against corrosion. Other finishes include epoxy resin coatings, black paint, and blackened surfaces.
- Chain Length: Standard shots measure approximately 27.5 meters, equipped with detachable links for ease of assembly and maintenance.
- Certification: Compliance with ISO 1704 and classification societies such as ABS, DNV, Lloyd's Register, Bureau Veritas, CCS, NK, KR, and RINA is mandatory for international acceptance.
The production of stud link anchor chains involves several critical steps to ensure the highest quality and durability:
- Selection of Raw Materials: Only premium alloy steels with precise chemical compositions are chosen to meet strength and toughness requirements.
- Forging and Shaping: Steel billets are heated and forged into the characteristic stud link shapes. The stud is welded inside each link to enhance mechanical properties.
- Heat Treatment: The chains undergo controlled heat treatment processes such as quenching and tempering to improve hardness and fatigue resistance.
- Surface Protection: Hot-dip galvanizing or other coating methods are applied to protect the chains from corrosion caused by seawater exposure.
- Quality Assurance: Each chain shot is subjected to rigorous testing, including proof load and breaking load tests, to verify compliance with standards.
- Marking and Certification: Chains are marked with batch numbers and manufacturer information for traceability and are certified by recognized classification societies.
Choosing stud link anchor chains from Spanish manufacturers and suppliers offers several benefits:
- Adherence to High Standards: Spanish companies strictly follow international quality and safety standards, ensuring reliable products.
- Technical Expertise and Customization: Many suppliers provide tailored solutions and technical consultation to meet specific project needs.

- Naval and Defense: Used by naval fleets for anchoring and securing military vessels.
- Port and Harbor Operations: Essential for mooring barges, tugs, and floating docks.
Proper maintenance and regular inspection are vital to ensure the longevity and safety of stud link anchor chains:
- Visual Inspections: Regular checks for corrosion, wear, elongation, and deformation.
- Non-Destructive Testing: Techniques such as magnetic particle inspection and ultrasonic testing to detect internal flaws.
- Re-Galvanization: Applying a fresh zinc coating to extend chain life and prevent corrosion.
- Replacement: Chains should be replaced when wear exceeds permissible limits or when cracks and defects are detected.
- Documentation: Maintaining detailed records of inspections and maintenance activities to comply with regulatory requirements.
