Abstract

A float device for use in laying a submarine pipeline from a launching base, comprising one or more tubes containing a liquid less dense than water, such as a hydrocarbon, and fixed to the pipeline so as to form therealong a plurality of compartments isolated from each other and each communicating with the sea via an opening or a pipe opening towards the bottom. Means may be provided for opening in each compartment a passage opening towards the top and for recovering the less dense liquid, driven by the water, to the outlet of said passages, or even for releasing the tube or tubes from the pipeline.
