Mooring Hawsers

Hongruntong Marine supplies professional mooring hawser and mooring hawser rope solutions including SBM mooring hawser and SPM mooring hawser for offshore operations.

Hongruntong Marine specializes in manufacturing high-performance mooring hawser systems designed for demanding offshore applications. Our comprehensive product range includes specialized SBM mooring hawser configurations for single buoy mooring systems and engineered SPM mooring hawser solutions for single point mooring operations. Each mooring hawser rope is precision-engineered to provide reliable vessel connectivity and exceptional energy absorption in challenging marine environments.

Our mooring hawser products represent the industry standard for vessel mooring safety, combining advanced materials technology with robust construction techniques. The SBM mooring hawser variants are specifically optimized for single buoy mooring applications, while our SPM mooring hawser solutions are engineered to withstand the dynamic loads encountered in single point mooring operations. Every mooring hawser rope in our product line undergoes rigorous quality control to ensure consistent performance and longevity in the most demanding offshore conditions.

Characteristics

FAQ

Q1: How do I choose between HMPE, polyester and nylon hawsers?
A1: HMPE offers the best strength-to-weight and lowest elongation (preferred for long SPM/SBM hawsers). Polyester gives balanced elasticity and shock absorption; nylon has higher stretch and is useful where energy absorption is prioritized. Provide your mooring loads and environment and we’ll recommend the optimal material.

Q2: Can you supply complete SPM/SBM hawser assemblies?
A2: Yes — we supply full assemblies including splices, soft eyes, thimbles, protective sleeves and certified fittings as a turnkey hawser package.

Q3: Do your hawsers meet OCIMF / international standards?
A3: Hawsers can be manufactured and tested to meet OCIMF, ISO and project-specific requirements. We can provide factory test reports and third-party inspection upon request.

Q4: What information do you need to recommend a hawser?
A4: Provide vessel displacement, mooring configuration (SPM/SBM), desired safety factor, environmental data (wind, wave, current) and target service life — we’ll deliver sizing calculations and options.

Q5: How are hawsers maintained and inspected?
A5: Regular visual inspections for chafe, UV degradation and splice integrity are recommended. Replace chafe sleeves when worn; perform periodic nondestructive testing of terminations where applicable.
