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.

The world's first pure ammonia-powered demonstration vessel, the "Anhui", successfully completed its maiden voyage in Hefei, Anhui, marking a major breakthrough in the industrial application of ammonia fuel in the field of ships. "Ammonia Hui" was jointly developed by the Energy Research Institute of the Hefei Comprehensive National Science Center and its subsidiary Shenzhen Haixu New Energy Co., Ltd. The ship is equipped with a 200-kilowatt high-speed gas internal combustion generator set, two 100-kilowatt propulsion motors and a twin-propeller propulsion system, with a full load of 50 tons and a rated speed of 10 knots.

Souce: Chinanews China reaches milestone in ocean-going salmon farming The world's first self-propelled closed salmon farming vessel "Suhai No. 1" was delivered in Nansha, Guangzhou on June 26, 2025, marking the beginning of China's move towards a new era of deep-sea salmon farming, and heralding that China's seafood consumption market will greatly reduce its dependence on imported chilled salmon in the future.

Main Application Fields And Case Analysis of Anchor Chain As the core material of marine engineering, anchor chain plays a key role in ship mooring, marine facility fixation, emergency operation and other fields with its high strength, corrosion resistance and reliability. The following is an explanation based on real cases:

​The anchor chain plays a vital role in the navigation and mooring of ships. It is a key component connecting the anchor and the ship. We often say "the ship stops at the anchor", but in fact the anchor is only the part that grips the ground. What really bears the huge pulling force of the ship is a complete set of "anchoring system", and the anchor chain is one of the most important parts of this system.

Anchor chain is one of the important mooring equipment of ships, and it bears the important responsibility of connecting anchors and hulls and fixing ship positions. It is exposed to seawater, wind and waves and friction all year round, and is one of the parts of the ship system that is most susceptible to corrosion and mechanical wear. Scientific maintenance of anchor chains can not only extend their service life, but also affect the safety of ship mooring. This article will systematically explain how to scientifically maintain anchor chains from the aspects of common damage, maintenance methods, maintenance cycles and inspection standards of anchor chains.

Although anchor chain and mooring chain are often referred to together, they play different roles in marine engineering. The following is an analysis from the aspects of definition, use, material, structure, manufacturing process and standards:

In the vast ocean, cage aquaculture is like a "granary on the sea", carrying the human desire for high-quality protein. However, under this seemingly calm water, a "food defense war" is quietly starting - feed waste, this seemingly insignificant problem, is like an invisible blade, piercing the hearts of farmers and threatening the balance of marine ecology.

I. Five Major Categories of Deck Outfitting Components Deck outfitting components are critical parts of ship operations, mainly divided into five categories: mooring equipment, cabin equipment, cargo handling devices, access facilities, and safety protection equipment. Today, we focus on the first two categories.

D Shackles-Primary Anchoring Methods for Industrial Lifting and Fastening Industrial applications heavily rely on high-strength forged D-shackles, especially for lifting and cargo securing as welded anchoring points. The analysis provides a comprehensive overview of material characteristics, welding methods, practical applications, and specific case studies.

We are a company with a strong environmental spirit. We make our earth healthier through every measure that can be improved. We applied for environmental management system certification very early. After data review and on-site audit, we passed the ISO 14001 environmental management system.

In China, GB/T 24816-2017 applies to short-link steel chains for general lifting purposes, primarily for Grade 8 chains with medium precision. The standard specifies dimensions, materials, manufacturing processes, acceptance criteria, and safety requirements.

The Beijing International Marine Engineering Technology and Equipment Exhibition (CM for short) was held at the Beijing China International Exhibition Center (New Hall) from March 26 to 28, 2025.

​As the core component of the ship's mooring system, the performance of the anchor chain depends not only on the material strength and specification grade, but also on the surface treatment process, which is a key factor that directly affects corrosion resistance, service life and maintenance cost. This article systematically sorts out the three mainstream surface treatment technologies of anchor chains - primary color treatment, black paint coating, and hot-dip galvanizing process, and conducts in-depth analysis from the technical principles, performance differences and scene adaptability.
