Abstract

A header for use in transmitting gases or fluids beneath the surface of a body of water is herein described. The header comprises a first pipe arranged for transmitting the gas or fluid, a second pipe arranged to hold either water or air and ballast means for adding weight to the header. Specifically, the ballast means is arranged such that the header floats on the surface of the body of water when the second pipe is filled with air. In use, the header is laid out across the surface of a body of water and the first pipe is connected to a source of the fluid to be transmitted, for example, air, oil, natural gas, or liquid hydrocarbons. Water is then pumped into the second pipe, which displaces the air in the second pipe and increases the specific weight of the header, thereby causing the header to sink below the surface of the body of water. As the header is below the surface, water traffic is not restricted by the transfer of fluid across the body of water. For maintenance, compressed air is pumped into the second pipe, replacing the water in the second pipe and causing the header to float to the surface of the body of water. This arrangement may also be used for aerating or de-icing bodies of water, such as, for example, lakes, channels and lagoons.
