A fluidified inert material spreading device configured to bury a pipeline in a body of water is configured to travel in the body of water in a travelling direction along and over the pipeline, and has a hull, which extends along a longitudinal axis, houses at least one expansion chamber for fluidified inert material, is connected to at least one feed port to feed the fluidified inert material to the expansion chamber, and has a quantity or number of outlet ports configured to release the fluidified inert material from the expansion chamber, close to the pipeline, and which as a whole define a flow cross section greater than the flow cross section of the feed port.

Fluidified inert material spreading device for burying an underwater pipeline, and method of spreading fluidified inert material over an underwater pipeline

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.
