Xue Long is a Chinese icebreaking research vessel. "Xuelong 3": China’s Polar Research Flagship Advances Toward Global Leadership As of December 2025, China’s first nuclear-powered icebreaker, Xuelong 3, remains under construction at Jiangnan Shipyard, with no launch or delivery date confirmed. Building on the legacy of Xuelong 1 (China’s inaugural polar research vessel) and Xuelong 2 (its first domestically built icebreaker), Xuelong 3 represents a third-generation leap, integrating nuclear propulsion and cutting-edge icebreaking technology to position China as a leader in polar science.

At sea, the anchor chain is the "lifeline" connecting a ship to the seabed when it is moored. An anchor chain of appropriate length is crucial for ship safety. So how much anchor chain is needed? This requires consideration of multiple factors.

Aquaculture, the controlled cultivation of fish, shellfish, and seaweed, is revolutionizing global food security. In 2022, aquaculture produced 126 million metric tons of seafood—52% of total global supply—with a compound annual growth rate (CAGR) of 5.8%. Yet, the industry faces a stark reality: the cost of a single mooring failure during a storm can exceed USD 2 million, often due to a single failed shackle or link.

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.

Marine aquaculture buoy anchoring systems require a scientifically optimized solution that combines buoys, anchor chains, and mooring discs to achieve stable connections, load distribution, and corrosion resistance.

Amidst the raging winds and waves on the sea, 10,000-ton giant ships remain as steady as a rock. The anchor chain, serving as the "steel backbone" of ship safety, is of utmost importance in terms of specifications, craftsmanship, and connection methods. This article will delve into how anchor chains safeguard ship safety from the perspectives of engineering standards, mechanical principles, deep-sea challenges, and innovation directions.

Mooring chocks are core components of ship deck fitting operations, responsible for guiding cables, distributing stress, and protecting the hull structure. However, frequent use and harsh environmental corrosion make them easily consumables. Damage not only affects operational efficiency but can also lead to maritime safety accidents. Therefore, we found a reliable and durable solution: the Stainless Mooring Chock Liner.

In the booming global maritime sector, environmental awareness is rising, and sustainable development is key to green maritime efforts. As a top anchor chain maker, we focus on quality production, innovation, and recycling discarded anchor chains for environmental protection.

​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.
