A floating modular system to support oil absorbent booms that provide continuous protection for enclosed or semi-enclosed water bodies from floating hydrocarbons. The invention refers to an anchored stable modular system, consisting of floats (3) hydrodynamic in shape to which are attached, by means of joints, oil absorbent booms (2). Tie-rods (6) connect the floats (3) to each other. The floating system allows the continuous use in the field of booms with absorbent material that selectively absorb oil from the surface of the water and may be applied in areas where surface drift current causes its perpendicular positioning and consequently that of the attached to it oil absorbent booms (2) against the direction of the current. This is due to the hydrodynamic shape of the distal floats (3). Generally, the special hydrodynamic features of the system allow it to use water circulation and finally to play the part of a stationary vacuum cleaner continuously absorbing oil from the surface of the water. The invention can be used for the continuous environmental protection of ports, lakes, marinas, etc.
