Abstract
This invention relates to a method and equipment to assist the flow of offshore oil production. At least three production flow lines are used, which are interconnected close to offshore well-heads or manifolds forming two U-shaped lengths of pipe acting as circuits for passage of the hydrocarbon mixture produced. A mechanical interface is periodically inserted into one flow line of the U-shaped branches of pipe and, driven by a volume of pressurized gas, travels along the one from among the two U-shaped pipe length to return to a gathering center. In its passage it pushes along the volume of hydrocarbon mixture which has accumulated in the flow lines.
