Juli Sling’s Five High-Performance Fiber Mooring Lines Achieve DNV-MEG4 Base Design Certification
August 4, 2026
A Major Breakthrough in Domestic High-Performance Fiber Applications for Advanced Offshore Mooring Systems
August 3, 2026 — Juli Sling, a leading provider of advanced lifting and marine rope solutions, has successfully obtained the DNV Mooring Line Base Design Certificate (BDC) for five types of its independently developed High-Performance Fiber Mooring Lines in accordance with the OCIMF MEG4 standard.
This achievement represents a significant breakthrough in the application of domestically produced high-performance fiber materials in high-end offshore engineering projects and demonstrates Juli Sling’s advanced capabilities in mooring line design, material innovation, manufacturing technology, and product validation.
The certification covers both mooring main lines and tail lines, providing offshore customers with a complete and reliable mooring solution portfolio for demanding marine applications.
DNV-MEG4 Certification Recognizes Advanced Mooring Line Performance
The OCIMF MEG4 (Mooring Equipment Guidelines, Fourth Edition) is one of the most widely adopted technical guidelines for mooring equipment used in oil tankers, LNG carriers, and offshore engineering projects.
Compared with traditional factory approval systems, the DNV-MEG4 Base Design Certification focuses on the design performance and technical reliability of specific mooring line products.
The certification process involves strict evaluation of:
- Raw material performance
- Mooring line structural design
- Manufacturing processes
- Mechanical performance testing
- Fatigue resistance
- Quality management systems
Through comprehensive testing and verification, Juli Sling’s certified products have demonstrated excellent performance and reliability required for advanced offshore applications.
Five High-Performance Fiber Mooring Lines Receive Certification
The certified products include five types of high-performance fiber solutions covering both main mooring lines and tail lines:
Certified Mooring Main Lines
Certified Mooring Tail Lines
- Polyamide Tail Lines
- Polyester/Polyolefin Tail Lines
The successful certification of multiple fiber materials enables Juli Sling to provide more comprehensive product options for offshore customers, supporting different application requirements in terms of strength, weight, fatigue resistance, abrasion resistance, and operational durability.
Innovation in Domestic Fiber Material and Manufacturing Technology
During the certification process, Juli Sling’s R&D team focused on optimizing the application potential of domestically produced high-performance fiber materials.
The team carried out continuous improvements in:
- Fiber material selection and compatibility
- Rope structure optimization
- Manufacturing process control
- Performance verification methods
Following the testing requirements specified in OCIMF MEG4 Appendix B, Juli Sling completed the required validation procedures and successfully achieved certification for both main mooring lines and tail lines.
This milestone demonstrates the company’s ability to integrate material innovation, structural engineering, and manufacturing expertise into high-performance marine rope solutions.
Supporting Global Offshore Engineering Applications
With the successful completion of the DNV-MEG4 Base Design Certification, Juli Sling is better positioned to support global offshore industries requiring reliable and high-performance mooring solutions.
The certified mooring line products are designed for applications including:
- Offshore oil and gas platforms
- Deep-water mooring systems
- Floating production facilities
- Offshore wind power projects
- Marine engineering applications
By combining advanced fiber materials with optimized rope structures, Juli Sling continues to provide safer, lighter, and more efficient mooring solutions for challenging offshore environments.
