Abstract: Increasingly frequent marine oil spills not only cause huge economic losses but also take a heavy toll on the environment. The use of oil containment booms is the major international method of removing oil spills. Aiming at the defects of existing booms such as poor tear resistance, poor low-temperature resistance and inconvenience in stowage, the paper focuses on the design of the fiber-reinforced layer of the float-type booms, and applies the designed leno weave technology to it, which greatly improves the interlayer adhesion strength and tear strength of the booms, and avoids the problem that the booms are easy to be scratched when spreading in the ice surface and on the shore. Under the premise that the floating part and the skirt of the boom can be separated, structural design and special treatment of the floating part can ensure the floatability of the boom and the reliability of the float and the skirt connection, as well as avoid affect the effect of oil containment due to the puncture of the air chamber in the course of the use of general booms. Meanwhile, the paper focuses on the process parameters of coating finishing on the molding and finishing of tape on the oil containment boom skirt. Based on that, the trial production of the tear-resistant separable float-type boom is completed; a relevant overall design process has been formed. The product has stronger comprehensive performance and higher cost performance than inflatable boom and solid float-type boom, and the results have the conditions for technology promotion and industrialization.
