A multi-diameter elastic sealing module for pigs, which operates in pipes having diameter changes, by being sent through the inside of a flexible or rigid pipe to move or draw various fittings and remove internal incrustations from the pipe, impelled by a fluid which flows inside said pipe. The sealing module comprises a sealing/impelling element (), a flexible core () covered by the sealing/impelling element (), a first clamping element (), a second clamping element (), a first fastening element () and a second fastening element ().

The present invention relates to a device intended to be passed through a pipeline of variable diameter, propelled by a liquid flowing inside said pipeline. The device has an elongated cylindrical body () made of polymer foam, with a number of deep channels () equally spaced from each other, coiled around the length of the cylindrical body () of the pig (), beginning close to one end of the body () and ending close to the other end. These ends have a basically bulled-nosed shape, conferring a symmetrical aspect. Structural cleaning elements (), not interconnected, are inserted inside the cylindrical body () of the pig. They are made of elastomeric material and have a central core () with spiral scraping extensions () of the same number as the deep channels () in the body () of the pig (). The spiral scraping extensions () are at an angle to the axis of the cylindrical body () of the pig () as well as to the scraping extensions () of the adjacent modules, inasmuch as they follow the configuration of the spiral channel ().

The invention is comprised of a Quick Anchoring Equipment system () which permits underwater connection and disconnection of anchoring lines () to anchoring devices that are already fixedly attached to the bottom of the sea. The Quick Anchoring Equipment () consists of chain cable, cables, hooks and buoys specifically organized and configured, which, are attached at the submerged end of the anchoring line (), which makes it possible with a single support boat (), together with a remote operated vehicle (), to carry out this whole anchoring lines () operation fundamental to floating platforms (). The invention also includes the method to install and uninstall the Quick Anchoring Equipment ().
