Shandong Lisheng Machinery Co., Ltd. is a new generation enterprise dedicated to the hardware industry. It is located in Jining City, Shandong Province, the hometown of Confucius and Mencius. The company is a professional hardware supporting enterprise integrating design, research and development, production and sales. The main products are chains, wire ropes and their accessories: shackles, turn buckles, clips, rings, snap hooks and other forgings and castings, and accept drawings and samples for processing.
It is evident that the anchor chain plays a vital role in conjunction with the anchor. However, since modern anchors are made from metal or from a rope, they stand a high chance of wear and tear related issues, such as rusting or chaffing.
The solution is to constantly monitor the anchor rode whenever it is hauled back on to the vessel.
For this, special stowage arrangements have to be made such that the rode is kept safely away from corrosive substances and so that it can be easily accessed for either maintenance or to paid out with the anchor.
The anchor plays a major role in a vessel and offshore operations. However, it can only function as long as it remains attached to the floating structure.
Considering the tremendous amounts of force applied to the connection between the anchor and the ship during routine berthing or anchoring conditions, conventional methods of securing the anchor will eventually fail under the extensive stress.
The anchor chain refers to the component that attaches the anchor to the boat or structure and is usually referred to as the anchor rode (or anchor cable). It is superior to conventional methods in terms of strength and load-bearing.
Proper maintenance and care are essential to ensure the longevity and reliability of the anchor chain. Regular inspections are necessary to identify any signs of wear, corrosion, or damage. The chain should be cleaned, lubricated, and protected against corrosion to mitigate the effects of the harsh marine environment.
In addition to visual inspections, regular tension tests and measurements are conducted to assess the chain's strength and integrity. Any damaged or worn links must be promptly repaired or replaced to maintain the chain's performance. Proper storage and handling in the chain locker are also crucial to prevent tangling or obstructions when deploying or retrieving the anchor.
The anchor chain consists of many chain links, and the size is expressed in chain diameter (mm). According to whether there is a strut in the middle of the chain ring, it is divided into nailed anchor chain and nailless anchor chain. Anchor chains can be made by forging, casting and welding.
The marine anchor chain is composed of several "sections" (shackles), each section is 25.0-27.5 meters long, and the sections are connected by chain links or shackles. After the anchor is lifted, the chain is stored in the chain locker in the bow. The specifications of the anchor chain are determined according to the ship construction standard.
The anchoring equipment of a ship comprises the anchor, anchor chain and the windlass. The anchoring equipment as required herewith is intended for temporary mooring of a ship within a harbour or sheltered area when the ship is awaiting berth, tide etc.
Determining how long your anchor rode should be is as simple as multiplying the deepest water you expect to anchor in by 8. As for rope size, the rule of thumb is 1/8" of rope diameter for every 9' of boat length.
Its primary purpose is to provide a mechanism for ships and boats to hold their position either during berthing and mooring operations at ports, or for large offshore installations such as semi-submersible oil rigs to remain stationary above an oil deposit.
