Abstract

A valve station for interconnecting boreholes in a seabed has a buoy anchored to the seabed and secured to a tanker whereby the buoy serves to anchor the tanker. Valves are provided on the buoy for connecting a plurality of separate pipelines extending from the boreholes to a common pipeline on the tanker. The buoy has an upstanding pipe extending through a shaft space in the stern of the tanker to a swivel connecting the pipe to the common pipeline on the tanker.
