Stud Link Anchor Chain is the most widely used anchor chain for commercial ships, offshore platforms, naval vessels, and marine mooring systems. Each chain link contains an internal stud that increases rigidity, limits deformation during loading, and improves resistance to twisting and kinking while the chain passes through the windlass and chain locker.

The chain is manufactured by flash butt welding, followed by calibration, heat treatment, dimensional inspection, proof load testing, and breaking load testing. Standard products are available in U1, U2, and U3 grades using CM490 or CM690 steel, covering nominal diameters from 12.5 mm to 90 mm. Standard delivery length is 25 m or 27.5 m per shot, with individual shots connected by Kenter shackles or joining shackles to form the complete anchor cable.

Stud Link Anchor Chain is widely used on bulk carriers, container ships, tankers, LNG carriers, offshore platforms, FPSOs, port facilities, and naval vessels. Matching accessories include end shackles, swivels, enlarged end links, joining shackles, and anchors to form a complete anchoring system.

Manufacturing Standards: Manufactured in accordance with ISO 1704, IACS Unified Requirement W18, IACS Unified Requirement A1, applicable EN, GB, and recognized shipbuilding specifications. Products are available for certification by ABS, BV, CCS, DNV, LR, NK, KR, RINA, RS, and RMRS according to customer requirements.

Testing Standards: Each chain undergoes chemical composition verification, mechanical property testing, dimensional inspection, flash weld inspection, proof load testing, and breaking load testing in accordance with the applicable classification society requirements. Heat treatment, hardness verification, visual inspection, calibration measurement, and permanent identification marking are completed before shipment. Material certificates, inspection reports, and full traceability documentation are supplied with every order.

Application Standards: Suitable for commercial ships, container vessels, bulk carriers, oil tankers, LNG and LPG carriers, offshore platforms, FPSOs, floating docks, naval vessels, port facilities, permanent mooring systems, and offshore wind projects.

Maintenance Standards: Inspect the chain regularly for wear, corrosion, elongation, cracked welds, deformed links, stud looseness, surface damage, and identification markings. Chain dimensions, wear allowance, and service condition should be evaluated according to the applicable IACS, classification society, and vessel maintenance requirements. Damaged or excessively worn chain sections should be replaced immediately to maintain anchoring system integrity.
