Mooring Hawsers
Hongruntong Marine’s Nylon Mooring Hawser delivers critical energy absorption for single point mooring (SPM) systems under extreme offshore conditions. Certified to OCIMF 2000 Guidelines for Offshore Tanker Operations, our hawsers provide >50% elongation at break – absorbing dynamic wave forces while preventing snap-back risks in CALM buoys, turrets, and FPSO applications.
Characteristics
● Manufactured and tested in accordance with the OCIMF 2000 Guidelines.
● NDBS: New Dry Breaking Strength / NWBS: New Wet breaking Strength.
● Specific gravity of swa water assume 1,025.
● Other sizes are available upon request (Maximum production size -Dia. 300mm).
