Sanya sightseeing cruise company fleet project for preventing microbial adhesion and enhancing sailing experience
A well-known sightseeing cruise company in Sanya owns a large fleet of 15 cruise ships, mainly operating popular sightseeing routes near the coast of Sanya. Due to the rich microbial resources in the coastal waters, the underwater parts of the cruise ships have long been seriously affected by microbial attachment.
A well-known sightseeing cruise company in Sanya owns a large fleet of 15 cruise ships, mainly operating popular sightseeing routes near the coast of Sanya. Due to the rich microbial resources in the coastal seawater, the underwater parts of the cruise ships have long been seriously troubled by microbial fouling. Large fouling organisms such as barnacles, tube worms, and bryozoans, as well as microscopic fouling organisms like bacteria and diatoms, densely attach to the ship hull surfaces. This not only significantly increases the overall weight of the cruise ships, causing a sharp rise in energy consumption, but also severely affects the aesthetic appearance and sailing stability of the ships. Moreover, the pungent odors generated by microbial attachment and growth greatly damage the tourists' sightseeing experience, causing the cruise company's customer satisfaction to drop from the original 80% to 60%, negatively impacting the company's market reputation and economic benefits.
Hisenmeike has carefully developed a comprehensive anti-microbial fouling nano-coating solution tailored to the actual conditions of this sightseeing cruise fleet. For the underwater parts of the ship hulls, a nano-coating with excellent anti-microbial fouling performance was applied. This coating captures an air layer through its superhydrophobic surface, creating an invisible barrier that effectively prevents marine organisms from adhering to the hull surface. At the same time, the antimicrobial agents contained in the coating can continuously and stably inhibit the growth and reproduction of microorganisms, thoroughly solving the problem of microbial fouling. For the ship's superstructure and deck areas, nano-coatings with self-cleaning and antibacterial functions were applied, making it difficult for dust, dirt, and other pollutants to adhere to the surface, while efficiently killing surface bacteria, thus maintaining a clean and hygienic internal environment of the cruise ships.
During the project implementation, Hisenmeike's technicians carried out meticulous construction operations on each cruise ship. First, the ship hull surfaces were deeply cleaned to ensure the coating could firmly and properly adhere. Then, the nano-coating was sprayed strictly according to standard procedures, fully ensuring the uniformity and integrity of the coating. After the project was completed and put into operation, close observation over four months showed that almost no new microbial fouling appeared on the ship hull surfaces, and the cleanliness of the hulls significantly improved. The energy consumption of the cruise ships also noticeably decreased, with fuel consumption per voyage reduced by about 10% compared to before. More importantly, the internal environment of the cruise ships was fundamentally improved, the odors completely disappeared, and customer satisfaction sharply rebounded to 90%, bringing significant economic benefits and a good market reputation to the cruise company.
