The studless mooring chain is a critical component for offshore anchoring systems, designed to deliver uncompromising reliability in the harshest marine environments. Engineered for stability and durability, this offshore mooring chain excels in securing floating structures, vessels, and offshore installations by withstanding extreme loads, corrosive seawater, and dynamic marine conditions. Unlike traditional chained solutions, the studless design optimizes weight distribution and load-bearing capacity, making it a preferred choice for projects requiring robust anchoring performance. Whether for offshore oil rigs, floating wind farms, or large-scale marine vessels, our studless mooring chain adheres to global standards, ensuring seamless integration with diverse mooring systems and long-term operational safety.
Link Type | Nominal Diameter (d) | Length (L) Formula | Width (W) Formula |
Common Stud Link | 34mm ~ 187mm (1-1/4” ~ 7-2/5”) | L = 6 × d | W = 3.35 × d |
Enlarged Stud Link | 1.1 × d | L = 6.6 × d | W = 3.69 × d |
End Stud Link | 1.2 × d | L = 6.75 × d | W = 4 × d |
Grade Options | ORQ, R3, R3S, R4, R4S, R5, R6 | - | - |
Material Standard | High-strength alloy steel (corrosion-resistant) | - | - |
Crafted from high-grade alloy steel, the studless mooring chain boasts superior tensile strength, enabling it to handle heavy loads and sudden impact forces in offshore settings. Its robust construction minimizes the risk of deformation or breakage, even under extreme weather conditions.
Engineered with anti-corrosive treatments, this offshore mooring chain resists saltwater erosion, rust, and marine fouling. The durable surface coating extends service life, reducing maintenance costs and ensuring consistent performance in long-term marine deployments.
Each link is manufactured to strict dimensional tolerances, following the formulas L = 6×d (for common links) and optimized width ratios. This precision ensures smooth operation with mooring winches, shackles, and other components, preventing jamming or premature wear.
We offer tailored studless mooring chain designs based on customer requirements, including custom diameters, lengths, and link configurations. Whether for specialized offshore projects or unique vessel specifications, our team delivers personalized solutions that meet exact operational needs.
All products strictly adhere to ISO 1704/ISO 20438/API 2F standards, guaranteeing compatibility with international mooring systems and regulatory requirements. This compliance ensures seamless integration and certification for global offshore projects.
The studless mooring chain is versatile for a wide range of offshore and marine applications:
Offshore oil and gas rigs (fixed and floating)
Floating wind farms and renewable energy installations
Large container ships, tankers, and bulk carriers
Marine research vessels and offshore support ships
Coastal and harbor mooring systems
Deep-sea anchoring operations
