Abstract

Generally, the present invention relates to a method for burying a pipe in a seabed. A dredging-excavator is usually needed when wanting to bury a pipe or a pipeline in a seabed. This can be difficult to implement and increase costs. The present invention comprises a pressurized water supply, and at least one nozzle connected to the pressurized water supply, wherein the nozzle is arranged on one side of the pipe to be buried to eject a pressurized water jet into the seabed to increase water content of the seabed below the pipe, so that the density of the seabed locally decreases below the density of the pipe allowing the pipe to supersede the seabed, and ejecting the water until the pipe has descended at the desired depth into the seabed.
