Formation of marine biofouling on ships

The long-term contact of ships with sea water causes a large number of bacteria to adhere to the surface of their materials, forming a layer of biological regulation film. The larvae and robes of the first generation of plankton landed on the biological regulation membrane one after another, secreting mucus that enhanced adhesion, and carried out strong adhesion and continuous reproduction through one or more cooperative operations of chemical bonding, electrostatic interaction, mechanical interlocking and diffusion interlocking. After the death of the old generation of organisms, some of them will not fall off automatically, and the new generation will reattach to its surface, eventually forming a large-scale biota.
Generally speaking, affected by environmental factors such as water salinity and water velocity, the organisms attached to the hull will die and fall off automatically. In fact, sea creatures such as shellfish hard shells will not automatically fall off after their death due to strong adhesion, which will become the basis for a new round of biological attachment. The main attachment parts are hull surface, propeller, propeller shaft, sonar chamber, seabed door, etc. The continuous accumulation and erosion of attachments will eventually cause ship fouling.
