<p>A submarine pipeline towing equipment including: a floater of prismatic shape with a horizontal or vertical axis, with a variable or partially variable buoyancy, whose lower base is at least partially open by an opening or hole to operate as an air chamber. The floater includes: at least one inlet including a valve through which air is supplied; at least one outlet including a valve through which air is discharged; an actuator to control the valve to supply air; an actuator to control the valve to discharge air; a mechanism connecting the equipment to the pipeline; a mechanism transferring air to the floater; a mechanism actuating the actuator to control the valve to supply air in function of a predefined level in the floater; and a mechanism actuating the actuator to control the valve to discharge air in function of the distance of the floater itself from the seabed.</p> |
