Abstract: A floating and maneuverable hull washing and cleaning plant for ships, includes cleaning and washing means submerged below the water level and operating against the hull, propulsion members for moving the plant in the engagement and washing against the hull in its length, members for controlling and changing the buoyancy displacement of the plant with control of the immersion level; a basin with side walls within which the cleaning and washing means are positioned, the cleaning and washing means being arranged in said basin and brought into contact with the hull during the cleaning with the control of the plant floating and of the position of the support members of the cleaning and washing means with respect to the basin itself; and guiding members for engaging and positioning the ship during the treatment.

Abstract: A system of anchorage of objects in grounds, includes an anchor base provided with tilted guides for rods or pins to be inserted upon assembly; said base being rigidly connected or having a releasable connection with the object or the structure to be anchored to the ground; and said base being provided with tilted guides in minimum number of three; said guides having parallelepiped crossing section in such a way as to house a rod, each guide, presenting a corresponding section and being inserted when assembling the anchorage to the ground; the single rod having hollow section shape, obtained by folding a sheet of rigid material; the hollow section being open at the folding ends of the rod with a minimum distance equal or higher to a fourth of the length of the side of the parallelepiped section on which it is made.
