Description
According to the current information on the buoy of the ship, the mooring buoy is a cylindrical mooring device floating on the water surface, commonly known as the water drum. Used for mooring mooring, for replenishment, shelter, cargo handling, degaussing or standby, etc., consisting of mooring rings, cylinders, anchor chains and anchors. The mooring ring is used to tie the ship's cable and transmit the ship's force to the steel ring of the anchor chain. There is a flat-type mooring ring and a plug-in mooring ring. The cylinder body has a large positive buoyancy, and one end of the anchor chain is floated out of the water surface to connect the mooring ring, and is subjected to the pulling force after the mooring, and has a gyro cylinder body, a cylindrical cylinder body and a square cylinder body, and does not rotate or tilt. The eccentric trough cylinder, the reversible double-cone cylindrical cylinder, the eccentric horizontal reversible cylinder, and the like. The anchor chain, the anchor and the mooring ring, the cylinder, and the transmission of the ship's force, are themselves subjected to tensile forces. The anchor is fixed to the seabed and is subjected to the tension of the mooring, with iron anchors and reinforced concrete anchors. The iron anchor has a naval anchor, a Hall anchor, a rocket embedded anchor, etc. The reinforced concrete anchor has a trapezoidal block, a frog block, a stack block, a mud sinking self-sinking anchor, etc., and can be laid flat or buried in the seabed.
The mooring buoys are divided into two types, A and B, for ships of different tonnages and lengths. Class A mooring buoys are used for ships of less than 183 meters in length. The spacing of each buoy is 427 meters. Underneath the buoys, there are two cast steel chain rings with a diameter of 90 mm and a length of 16.5 meters. The sinking block requires a 298-ton tensile test. The ship float is checked once a month. The chain is used for one year. If the chain diameter is less than 76 mm, it will be replaced. Class B mooring buoys are available for ships with a length of 113 meters or less and a capacity of 6,000 tons. The floats are separated by 305 meters. Underneath the buoys, there are two cast steels with a diameter of 76 mm and a length of 16.5 meters. The chain ring has a weight of 50 tons of submerged block. Each of the subordinates needs to pass the 219-ton tensile test. The ship float is checked once a month, and the tether is used for one year. If the chain diameter is less than 64 mm. It will be replaced.
Corresponding to different tonnage vessels, different anchoring buoys, various types of mooring buoys, can be used for mooring of different tonnage vessels, and it is very convenient and flexible to operate with mooring and mooring vessels. The cargo transfer operation and the maintenance of the ship can be carried out on the berth. Therefore, the mooring buoy is an important anchoring facility for the port. .
The pontoon adopts the upper and lower flat bottoms and four watertight compartment main floating body structures, with a diameter of 2.1 meters and a height of 1.1 meters. The manufacturing process adopts a cutting joint and is subjected to sanding treatment, pressure test to take air pressure detection treatment, and all steel materials are sandblasted and rust-removed and air-sprayed. It has the characteristics of easy delivery, easy identification, easy connection, easy maintenance, scientific design, reasonable structure, convenient use and high technical content.
