Magnesium Anode
Multi buoy mooring system
Multi buoy mooring system (MBM), a facility of traditional buoy mooring systems, through which ships are typically moored by a combination of anchor and stern mooring buoys, and fixed to a fixed heading. Also known as conventional buoy mooring.
Single point mooring system
Single Point Mooring (SPM) is a facility that fixes a ship to a single buoy or structure through the bow and swings freely with prevailing winds and currents. Three types of single point mooring systems are commonly used: catenary anchor leg mooring, single anchor leg mooring, and turret mooring.
Single Point Mooring (SPM) is a type of floating buoy/dock anchored at sea, allowing for the loading and unloading of liquid cargo such as ships' petroleum products. SPM is mainly used in areas without dedicated facilities for loading and unloading liquid cargo. These single point mooring (SPM) facilities are located a few kilometers away from coastal facilities, connected through submarine and subsea oil pipelines, and can even handle ultra large capacity ships such as VLCC.
Single point mooring (SPM) serves as a connection between onshore facilities and ships, used for loading or unloading liquid and gas cargo.
Some of the main benefits of using SPM are:
*Handling ultra large vessels.
*No need for ships to arrive at the port, saving fuel and time.
*Ships with high draft can be easily moored.
*High quality goods are easy to handle.

Magnesium Anode
Our company produces magnesium alloy sacrificial anode by using high quality raw materials, mature production technology and advanced equipment inspection, to ensure that every anode is in line with national standards.
1. Small proportion, with a high chemical activity;
2. The potential is negative and the driving potential is large;
3. Large theoretical capacity and low polarization;
4. Especially suitable for high resistivity medium
(If the resistivity is greater than 100Ω•m, the ribbon magnesium anode is proposed)
Implementing Standards
GB/T 17731-2009 “Magnesium Alloy Sacrificial Anode”
GB/T 21488-2008 “Technical Specification for Cathodic Protection of Buried Steel Pipeline”
Scope of Application
Applicable to anti-corrosion protection of the oil, gas, water supply and drainage pipelines in soil medium, as well as the protection of harbor, ship, reservoir gate and other projects in water.
Magnesium Sacrificial Anode Classifications
1. Magnesium Alloy Anode for Oil Well Casing
2. Prepackaged Magnesium Alloy Sacrificial Anode with Backfill
3. High Potential Magnesium Alloy Sacrificial Anode D Type
4. Extruded Ribbon Type Magnesium Alloy Sacrificial Anode
5. Extruded Magnesium Anode Rod
Matters Need Attention in Use
1. Avoiding the collision with the steel structure;
2. Should be buried in the low-lying and damp places; the anode must be packed in filling bag before being buried in soil;
3. After being placed in the ground, the filling bag with anodes should be soaked with water before being covered by soil.
