On May 11, 2026, a Chinese offshore farming vessel named Guoxin 1-2 completed its first commercial harvest of Atlantic salmon. The batch: 12 tons. The vessel's stated annual capacity: 3,742 tons. The Guoxin 1-2 is a 150,000-ton mobile vessel with 15 farming tanks totaling nearly 100,000 cubic meters of water volume. It draws cold seawater from 30-50 meters below the surface (10-16°C year-round) and moves along China's coastline to follow optimal temperatures. This is a mobile closed-containment system, not a fixed platform.

DIN 763 is a German industrial standard that specifies round steel link chains with a long link design. The key feature is that the inner length (a) is significantly larger than the inner width (b) – typically 3 times or more. This gives the chain a stretched appearance, making it easy to hook, loop, or wrap around objects.

This article mainly introduces a real order for CM690-76mm stud anchor chains from Canada, specifically designed for offshore operations and ABS-certified vessels, and details the ABS-certified manufacturing process.

A customer needed 4 pcs of 60kg stainless steel AC-14 anchors. Most suppliers said no. We said yes – and delivered 30 days faster, 30% lower cost. Then a Chile salmon client wanted a custom G80 mooring ring. We re-engineered it. Cost down 40%. Strength up 1.3x. This is how we work. Read on.

There are four common types of German standard DIN chains: DIN 763, DIN 764, DIN 766, and DIN 5685. The main differences between them are link length and application. As a professional supplier, SMEOCEAN helps you understand each type at a glance.

What Are Anchor Chain Accessories? Complete Guide to Anchor Shackles, Kenter Shackles, Swivel Groups & More In marine engineering, we often focus on the strength and corrosion resistance of anchor chains. But few people know: how are anchor chain sections connected to each other? Why does a several-hundred-meter-long anchor chain, when deployed into deep water, not twist up like a telephone cord? Today, let's get to know the other important members of the mooring system – anchor chain accessories.

Double dogbone shackles are a key component of the chain tensioning system** in bridge engineering. Their dogbone design allows for automatic alignment, reduces stress concentration, and extends service life.

In ship towing operations, the towing chain is the core component connecting the tugboat and the towed vessel, undertaking the crucial functions of transmitting towing force and maintaining course stability. This article will systematically introduce the technical characteristics of ship towing chains from aspects such as structural composition, core function, and technical parameters.

March 23 marked World Meteorological Day. On that day, the World Meteorological Organization (WMO) released its *State of the Global Climate 2025* report, which highlighted that the degree of Earth's energy imbalance has reached its highest level since observational records began in 1960.
