Galvanic 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.
