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.

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.

In the past three years, China's salmon farming industry has shown a rapid growth trend, with technological breakthroughs and industrial upgrading advancing simultaneously: Production increase: Domestic salmon production has increased from about 30,000 tons in 2021 to nearly 50,000 tons in 2023, with an average annual growth rate of more than 15%, of which Longyangxia in Qinghai and Yili in Xinjiang have made significant contributions. Technological breakthroughs: Deep-sea aquaculture equipment (such as Qingdao's "Deep Blue No. 1") has been applied on a large scale, promoting the expansion of aquaculture from nearshore to deep sea; inland Xinjiang has broken through geographical restrictions through land-based circulating water systems to achieve efficient aquaculture of cold-water fish. Market expansion: Domestic consumer demand has surged, and salmon has moved from high-end restaurants to family tables. At the same time, exports have steadily increased, and products are exported to Russia, Southeast Asia and Europe. Brand building: Regional brands such as Qinghai's "Longyangxia" and Xinjiang's "Tianyun" have gradually formed, and the full industrial chain model (from aquaculture to processing and cold chain logistics) has become increasingly perfect.

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.

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.
