Marine shipping is considered one of the safest forms of cargo transport with an improved environmental profile. Indeed, around 90% of the world’s goods are transported by sea. If a ship’s hull is left untreated, it collects marine organisms such as barnacles, mussels and algae that create drag as the ship travels through water. This can increase fuel consumption by more than 40%, not only adding massive costs but also increasing the use of valuable fuel resources. Microbial control technology is a key component of the antifouling paints that are used to keep ships’ hulls clean and free from these unwanted marine organisms. The use of antifouling coatings also helps control the translocation of marine species from one continent to another. Left to travel unhindered on the bottom of ships, marine species from one region can translocate in sufficient numbers as to become a significant threat to native species in their new habitat. Modern microbial technology, used in the latest antifouling paints, is developed with the environment in mind.
