At the port of Antwerp, dogs play a crucial role in monitoring pipelines for gas leaks, complementing technology that is less effective underground. Geert Heytens from TotalEnergies oversees over 400 kilometers of pipelines, with about 80 in the port area. Trained by Intero The Sniffers, dogs like Trix, a Belgian Shepherd, begin training as puppies to detect specific petrochemical gases. While their primary task is not leak detection, their keen sense of smell enables immediate intervention if necessary, ensuring safe transport of flammable materials like ethylene and propylene.
