Barnacles are dangerous. A barnacle is an arthropod with a limy shell attached to seaside rocks, often forming dense colonies. Barnacles are attached to coastal docks, ship bottoms, submarine cables, etc., often causing great harm. Its hazards are as follows: 1, increase the ship resistance consumption of fuel: due to the attachment of barnacles, making the ship below the waterline roughness increased, so that the ship in the navigation of the resistance increased, at the same time also increased the weight of the ship led to the ship, the ship's navigation speed decreased, increased fuel consumption. 2. Increase the dead weight and weaken the anti-risk ability: if the offshore oil platform and construction facilities are attached by barnacles, the dead weight of these facilities will be increased, the external load will be increased, and the ability to resist storm waves will be weakened. 3. Affect the comprehensive utilization of seawater resources: barnacles will block the water supply and drainage pipelines of oil platforms and power plants that use seawater for cooling, affecting the cooling effect of seawater. 4, hinder the use of instruments and equipment: barnacles attached to hinder the normal work of military facilities and civilian, scientific research instruments, reduce the sensitivity of sensors, instruments and transmission components. 5. Affect fishery production and reduce the quality of aquatic products: barnacle attachment affects aquaculture, competes with shellfish for attachment base and bait, blocks mesh, affects water exchange, hinders the growth and development of aquaculture objects, and reduces the quality of aquatic products. 6. Accelerate the local corrosion rate of underwater fixation: the attachment of barnacles will change the electrochemical corrosion process and speed of local metal, resulting in local corrosion or perforation.
