Detailed Product Advantages
Our offshore rigging system is designed to minimize downtime and maximize safety on drilling platforms, FPSOs, and subsea installations. The 316L stainless steel construction provides exceptional resistance to pitting and crevice corrosion, even in high-chloride environments. Unlike standard carbon steel rigging, our system eliminates the need for frequent coating inspections and replacements, reducing total cost of ownership.
Key Benefits for Your Operations:
- Extended service life in marine and sour gas conditions – up to 5× longer than 304 stainless or galvanized alternatives.
- Reduced risk of catastrophic failure thanks to full traceability and lot-controlled material certification.
- Easy integration with existing lifting and mooring hardware – compatible with standard offshore shackles, hooks, and chain systems.
- Comprehensive test reports provided with each order – including dimensional, chemical, and mechanical property certificates.
- Global logistics support – shipped from Tianjin, Qingdao, Shanghai, or Foshan ports to your project site anywhere in the world.

Frequently Asked Questions (FAQ)
-
Q: Is the 10 Ton SWL rating for a single leg or a sling assembly?
A: The SWL rating applies to the complete rigging assembly as configured. For multi-leg slings, the SWL is based on the included design factor (typically 4:1). We can provide detailed capacity charts for your specific configuration. -
Q: What length options are available for this rigging system?
A: Standard lengths range from 1 meter to 20 meters. Custom lengths are available upon request, and we can adjust the number of lifting points or termination type accordingly. -
Q: Does the 3-year warranty cover corrosion or wear-and-tear?
A: The warranty covers defects in material and workmanship under normal operating conditions. Corrosion that occurs due to chemical exposure beyond the designed resistance (e.g., strong acids not covered by NACE MR0175) is not included. Please consult our technical team for specific environmental compatibility. -
Q: Can you provide NACE MR0175 material certificates for the 316L stainless steel?
A: Yes, we supply mill test certificates (MTC) that confirm compliance with NACE MR0175 / ISO 15156, including chemical composition and mechanical properties. Third-party inspection can also be arranged at additional cost. -
Q: What is the typical lead time for a custom offshore rigging system?
A: For standard configurations, lead time is 2–4 weeks. Custom designs may require 4–6 weeks depending on complexity and material availability. We can expedite urgent orders subject to production capacity. -
Q: Do you offer installation or on-site training?
A: We provide detailed installation manuals and technical support via email/phone. On-site training can be arranged for large orders, but travel and accommodation costs are extra. -
Q: How are the rigging components packaged for offshore shipment?
A: Each assembly is individually labeled, wrapped in anti-corrosion paper, and packed in wooden crates suitable for sea freight. We can also supply export-grade packaging with waterproof membranes upon request. -
Q: Is this rigging system suitable for use in subsea applications (e.g., ROV deployment)?
A: Yes, the 316L stainless steel and NACE MR0175 compliance make it suitable for subsea lifting and mooring up to 500 meters depth. For deeper applications, we recommend a review of the specific load and environmental conditions.
