A permanent mooring method and arrangement for embedding a permanent mooring device in the sea bottom calls for the lowering of the permanent mooring device into the sea until the bottom end contacts the sea bottom, the transmission of fluid under high pressure via a hollow tubular body of the permanent mooring device to a nozzle portion thereof so as to create a fluidized area in the sea bottom around the permanent mooring device and to wash the permanent mooring device into and beneath the sea bottom, followed by transmission of a cementitious substance via the hollow tubular body to the nozzle portion so as to fill the fluidized area in the sea bottom with the cementitious substance. The permanent mooring device is vibrated during transmission of the high-pressure fluid, transmission of the cementitious substance, or consolidation of the cementitious substance, or during any combination thereof to assist in the embedding process. Other features of the invention include: provision of releasable flukes surrounding the tubular portion of the permanent mooring device; the provision of restraints for limiting the outward pivotal movement of the flukes; the provision of primary and secondary nozzles in the tubular portion of the permanent mooring device; the provision of a valve for controlling the flow of high-pressure fluid and/or cementitious substance; provision of a quick-release arrangement between pipe extensions used to lower the device and the tubular portion of the device, once it is embedded; and the provision of a shackle and shackle bar arrangement which is free of electrolytic current flow, and thus less susceptible to corrosion.
