The marine anchor is a crucial device for maritime operations. It helps to maintain the safe and smooth operations of ships. To enhance the efficiency and security of marine operations, it is needed to understand the properties of the product and consider how to choose the most suitable one.
Brief Introduction of Marine Anchor
Marine anchor is the equipment used to fix the position and direction of the ship, and it is the core component of ship anchoring equipment. It can be connected to the ship by an anchor chain or anchor rope so that the ship can be fixed on the surface of the water to avoid drifting due to the influence of wind, waves, and currents.
Structure of The Marine Anchor
Marine anchor is mainly composed of two parts: Anchor body and anchor rod. The anchor body is generally Y-shaped or T-shaped, which is used to fix the seabed, and the anchor rod is the part where the anchor body is connected with the anchor chain. The length of the anchor rod and the number of anchor chains are related to the specifications of the anchor. The anchor is also equipped with some accessories, such as anchor tip (anchor ring at anchor tail), anchor hook, and anchor rope, which can help the anchor to be firmly fixed on the seabed.
Functions of Marine Anchor
Fixed ship position
The anchor embeds in the sediment or hooks the obstacles at the bottom of the water through the claws, and uses its own weight and grasping force to stabilize the ship at a specific position. This process requires the cooperation of the anchor chain, and the part of the anchor chain lying on the seabed further enhances the fixing effect through friction.
Buffer external impact
The anchor chain is curved in the water, which can absorb the impact of wind, waves, and current on the ship and reduce the ship sloshing. The anchor chain lying on the seabed shares part of the external force through its own gravity, so as to prevent the anchor claw from coming out due to excessive instantaneous tension.
Adapt to different ship needs
There are various types of anchors such as naval anchor and large-grip anchor, which are selected according to the tonnage of the ship and the berthing environment. For example, large ships need heavier anchors and longer anchor chains to cope with greater inertia force.
Modern anchor designs such as four-claw iron anchors optimize the bottom grasping performance, and some special anchors can even be used in deep sea or special geological conditions.
Problems to Be Considered in Selecting High-quality Marine Anchor
An anchor for sale is one of the most important safety devices when a ship is moored, which can fix the position of the ship and prevent it from drifting away from its original position under the influence of natural factors such as water currents and wind waves. When choosing an anchor for boat, the following aspects should be considered to ensure its reliability, durability, and safety:
High strength and corrosion resistance: High-quality anchors for boats should have high strength and corrosion resistance, and can be used for a long time in harsh environments without damage or fracture. High-strength cast steel or forged steel is usually used to ensure tensile strength and impact resistance.
Strong grip: A high-quality anchor should have great friction and grip, be able to maintain stability on various terrains, and effectively fix the position of the ship.
Simple and convenient operation: The use of high-quality anchors should have a simple and easy operation mode, do not need too much maintenance and repair work, and can be installed and disassembled quickly and accurately.
The Best Marine Anchor Material
The selection of materials directly affects the performance and service life of anchors for sale. High-quality materials can ensure the anchor works stably in complex and changeable marine environments and improve navigation safety. At the same time, reasonable material selection can also reduce maintenance costs and improve economic benefits.
Carbon steel: Carbon steel has the characteristics of high strength and is suitable for large merchant ships and engineering anchors. Its cost is low and it is easy to process and weld. However, carbon steel needs anti-corrosion treatment, such as zinc plating and painting, otherwise, it will rust easily. This material is usually used in Stockless Anchor, Admiralty Anchor, and some Plow Anchor.
Alloy steel: Alloy steel has higher strength and wear resistance, so it is more suitable for deep-sea or harsh environments. At the same time, because of its impact resistance, it is more suitable for rocks or coral reef seabed. In order to improve its performance, heat treatment is needed.
Alloy steel is usually used in deep-sea mooring systems, oil platform mooring anchors, and military ship anchors.
Stainless steel: Stainless steel is characterized by excellent corrosion resistance and is suitable for seawater environments. And its appearance is beautiful, often used in yachts and high-end ships. However, the cost of this material is high, and its strength is usually lower than that of alloy steel. Alloy steel is mainly used for yacht anchors, sailing anchors, and long-term mooring buoy anchors.
Cast iron: The cost of cast iron is extremely low, but it is brittle and easy to break. In addition, it has poor corrosion resistance and needs to be protected by zinc plating or coating. This feature makes it mainly used for small temporary anchors. In general, cast iron is used to make temporary mooring anchors, small fishing boat anchors, and dock mooring anchors.
