Mooring Chain Specs: wire_rope
Offshore mooring and anchor chain specifications per IACS UR W22 (studless) and IACS UR W7 (studlink). Chain grades R3, R3S, R4, R4S, R5 with nominal diameters 16–162 mm. Properties: minimum breaking load (MBL) in kN, proof load in kN, weight per unit length in kg/m, link length and width in mm, Young's modulus in GPa. Also includes wire rope (6×19, 6×37, spiral strand) and polyester rope (3-strand, braided) entries for taut-leg mooring system comparison per API RP 2SK.
