​In the frozen waters of the Earth's poles, icebreakers tow giant drilling platforms, cutting through the waves, while floating production storage and offloading (FPSO) units remain as stable as rocks amidst raging winds and towering waves. Behind these feats of humankind challenging extreme cold environments lies a key technology—extreme cold anchor chains. As the "lifeline" connecting marine engineering equipment to the seabed, extreme cold anchor chains are writing a legend of Chinese manufacturing, from catching up to leading, in extreme environments of -40°C and even -60°C.

The initial expectation was simple: US tariffs would severely damage Chinese manufacturing, causing global buyers to withdraw. However, things didn't go as planned. With the dust settling on the 2025 tariff storm, China's anchor chain industry not only survived but also integrated, upgraded, and became a more reliable partner for international buyers. Here's the truth behind the events and its importance for your next purchasing decisions.

On October 28th, the "Norway-China Seafood Summit 2025" was held in Qingdao as scheduled. On the eve of the 28th China International Fisheries Expo, this conference became the focus of the global seafood industry. Representatives from the Norwegian Seafood Council, Chinese importers, and e-commerce platforms discussed the future direction of Sino-Norwegian seafood trade. Data shows that China has become Norway's third-largest seafood export market, with a growth rate far exceeding that of Europe and the United States.

CFSE 2025: Global Salmon & Aquaculture Innovation Summit Qingdao, China | 29-31 Oct 2025 Organisers with 29-Year Track Record Hosted by China Council for the Promotion of International Trade (Agriculture Sub-Council) and supported by FAO and the Chinese Academy of Fishery Sciences, CFSE has grown from a few thousand m² in 1996 to 140,000 m² today—the only event that covers the entire aquatic protein supply chain.

Anchor Chain Safety Alert: How to Protect Ship Safety When the "Lifeline" Exceeds Limit Wear? —Analysis of the Critical Lines of Defense for Global Ship Safety Anchor chains are the "lifeline" of a ship, but when they rust or exceed limits due to wear, they can cause loss of control, damage to submarine facilities, and even casualties. In April 2025, a Chinese cargo ship (1,422 gross tons) was urgently grounded by the China Maritime Safety Administration due to anchor chain diameter wear exceeding 28%. This case sounded a safety alarm for the industry. This article combines the "Technical Code for Mandatory Surveys of International Seagoing Vessels" with actual engineering data to provide global procurement decision-makers with an authoritative guide to anchor chain replacement.

In the vast and unpredictable expanse of the ocean, where ships navigate through treacherous waters and face the fury of nature, a seemingly unassuming yet absolutely vital component stands as the silent guardian of maritime safety: the anchor chain. This unassuming piece of equipment, often overlooked by the untrained eye, is in fact the core of a ship's mooring system, acting as a resilient bond that secures the vessel against the relentless forces of turbulent winds and waves.

Amidst the raging winds and waves of the Norwegian fjords, or under the impact of the cold snap in southern Chile, a single broken anchor chain can cause a school of salmon worth millions of euros to escape within hours. Anchor chains are not only tools for securing cages but also a core line of defense against natural risks, safeguarding aquaculture profits. According to the 2023 White Paper on Aquaculture Facility Safety published by the Norwegian Ministry of Fisheries and Seafood (Fiskeri- og havbruksnæringen), 68% of the salmon escapes in Norway from 2018 to 2023 that were due to broken anchor chains were directly related to improper selection, with an average loss of over 1.8 million euros per incident. Statistics from the Aquaculture Stewardship Council Chile show that cage drifting caused by anchor chain corrosion in southern Chilean waters accounted for 42% of the escapes that year. As an anchor chain manufacturer, we understand that scientific anchor chain selection can reduce risk by 90%, while a poor choice can undo ten years of hard work. Drawing on real-world examples, this article provides key anchor chain selection strategies for salmon farmers in Norway and Chile.

Recently, the world's first commercial underwater data center project powered by offshore wind power officially launched off the coast of Shanghai. As a new computing power solution for the AI era, this groundbreaking project provides a new reference path for the future development of green, low-carbon computing power, and also marks a new phase of "underwater" development for global intelligent computing infrastructure.

China is the world's largest anchor chain producer, exporting 352,000 tons of anchor chain in 2019, accounting for over 65% of the global market share. According to customs HS codes, anchor chains are primarily divided into two categories: 73158100 (Japanese-style link chain): 2019 exports of 132,000 tons, valued at US$193 million, and a unit price of approximately US$1,462 per ton; 73158200 (Other welded chain): 2019 exports of 219,700 tons, valued at US$325 million, and a unit price of approximately US$1,479 per ton.
