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.

This tender project is located in Southeast Asian waters. The client plans to deploy a new single-point mooring system for oil loading and unloading operations between offshore oil drilling platforms and tankers. As the hardware supplier of the mooring system, SMEOCEAN was deeply involved in the entire project, including testing of products such as chains and accessories, technical support, and bid preparation. The CALM (Catenary Anchor Leg Mooring) buoy is a typical single-point mooring system, widely used in deepwater and offshore oil loading and unloading operations worldwide. The system uses multiple catenary anchor chains to secure the buoy in the deep sea, allowing tankers to maneuver freely around the buoy, creating a "weather vane" effect and effectively reducing the forces exerted on the mooring system by wind, waves, and currents.

In industrial lifting and freight transportation, chains are a core element for load safety and efficiency. Different grades of chain, varying by implementation standards, manufacturing processes, and load-bearing performance, are widely used in applications such as lifting, transport, and securing. As representatives of high-strength products, G80 and G70 chains share similarities but also significant differences in technical specifications, surface treatment, and application targets. Selecting the appropriate grade of chain is crucial for ensuring operational safety and improving efficiency. This article will provide a professional perspective on the core features, implementation standards, and application scenarios of the two, comparing the differences to assist with selection and facilitate search engine crawling, addressing key trends in industrial chain selection.

The Load Binder (Ratchet Tiedown) is a mechanical device designed specifically for transport applications. It utilizes a ratchet-pawl mechanism to tighten the chain tooth by tooth, applying continuous and controllable tension to the load. This feature ensures cargo is securely positioned during transport, effectively preventing it from sliding, tipping, or falling. Compared to traditional lever-type tiedowns, ratchet tiedowns are easier to operate, can be fine-tuned with one hand, and do not instantly spring back when released, offering significant safety advantages. As such, it has become the preferred standard tiedown device in road transport regulations in Europe, the United States, and Australia.

In the field of marine engineering, mooring systems are crucial for ensuring the safe and stable operation of offshore facilities (such as ships and offshore platforms). As a key component of mooring chains, the rational selection of their parameters directly impacts their performance and reliability. The complex and dynamic seawater environment presents a variety of factors that significantly influence mooring chain parameter selection. This article focuses on the factors influencing mooring chain parameter selection in seawater, explains the importance of mooring analysis, and explores the impact of environmental factors such as currents, tides, and wind, as well as the inherent characteristics of the mooring system, on mooring chain parameter selection. Sinostar Marine, at the forefront of the marine industry, provides professional mooring analysis services and has accumulated extensive experience in mooring chain parameter selection. This article will draw on its practical experience to conduct an in-depth analysis of the relevant influencing factors, providing a theoretical basis and practical reference for the optimal selection of mooring chain parameters.

The maiden voyage of the "Senhai Pioneer": Ushering in a new era of deep-sea aquaculture The delivery of the "Senhai Pioneer" was like a bombshell, pressing the accelerator for China's deep-sea aquaculture. This 80,000-ton seagoing aquaculture vessel has decisively broken the saturation of nearshore cages and the reliance on the weather for food. With its innovative design and superior performance, it has become a new benchmark for the "blue granary," leading China's marine aquaculture industry from "nearshore farming" to "deep-sea grazing and fishing."

​In the shipbuilding and offshore engineering sectors, the choice between original and black Tar anchor chain isn't a simple "superiority" debate; it's a precise match based on quality control logic, project suitability, and lifecycle costs. The following analysis, focusing on core value dimensions, will help you make a more rational decision:

When it comes to salmon, people often think of the magnificent seascape of the Norwegian fjords or the turbulent waves of the Chilean coast. After all, in traditional concepts, salmon is the "darling" of the ocean. However, in Xinjiang, China, a salmon farming base has miraculously emerged on this vast inland land separated from the sea by thousands of mountains and rivers. This phenomenon that breaks conventional cognition is like a stone thrown into a calm lake, arousing people's imagination of the infinite possibilities of inland aquaculture.

Longyangxia salmon: the "golden legend" in the cold water of the plateau. In the world of food, salmon is a well-known existence. It has tender and smooth meat, rich in high-quality protein and unsaturated fatty acids, and is very nutritious. Many people around the world love it. In the past, Norway, a traditional salmon farming powerhouse, dominated the global market. If we want to eat salmon, we have to rely on imports.
