December 2-5, 2025 | Shanghai New International Expo Centre  

As floating wind farms, ammonia-fuelled VLCCs and mega-FPSOs crowd the order-books, the once-traditional anchor-chain sector is gearing up for its fastest technology sprint in decades. Here are the five headlines you will hear repeated on the show floor. 

1. New Strength — R6 Ultra-High-Tensile Chain  

Chinese mills have moved from pilot to serial production of R6 grade (≥1,100 MPa yield). Weight per metre is 18% lower than R5, cutting payload and installation cost for 16-20 MW turbines. Expect ten-plus technical papers on heat-treatment windows and low-temperature toughness during the conference. 

2. New Size — Ø300 mm Super Links  

Factory-qualified welding and quenching of Ø300 mm chain gives a breaking load above 6,000 kN—enough for 1,000 m water-depth floaters. Ø200-Ø300 mm will become the standard floating-wind in 2026. 

3. New Holding — Integrated Deep-Water Anchor Piles  

The old “chain + gravity block” recipe is shifting to “chain + pile”. T-120 piles target ≥60 m depth, cut installation time from 48 h to 10 min and shave CAPEX by ~15%. A full-scale mock-up will be on display and has been added to the Floating Wind JIP reference list. 

4. New Sensing — Digital-Twin Links  

Fiber-Bragg-grating strain and temperature sensors embedded in common links have finished sea trials. Real-time data feeds digital-twin platforms that predict remaining fatigue life. The first BV-type-approved commercial strings are expected in 2026, enabling unmanned terminals and remote O&M. 

5. New Capacity — 80 kt Deep-Sea Mooring Plant  

A CNY 300 million, 80 kt/year deep-sea mooring plant announced in November will lift national anchor-chain capacity to 140 kt, with deep-water products likely >50% of output. Shorter lead times and more stable supply chains are on the horizon for global floating-wind EPCs. 

Industry Snapshot  

“Deeper, Larger, Lighter, Smarter” is the agreed roadmap: R6→R7 steel grades, 70 mm→300 mm diameters, chain-pile integration and sensor-equipped twins—all aligned with floating renewables and deep-oil developments.

Wishing Marintec China 2025 every success! SMEOCEAN looks forward to meeting old and new friends in Shanghai and mapping out the next chapter of mooring technology together.
