Abstract

A mooring apparatus for securing a mooring line for a floating rig or the like, includes a soil penetration means, an anchoring means, and coiled tubing or the like, the soil penetration means and anchoring means being arranged upon the coiled tubing. Fluid may be pumped down the coiled tubing to drive the soil penetration means, or to activate the anchor. A transmission cable, to control the mooring system or supply it with power, may also be disposed along the coiled tubing. Various penetration means, such as drill and helical augers may be used. For soft soil, the soil penetration means may include nozzles to erode the soil. The soil penetration means may either be retracted, of sacrificed to form part of the anchor. The anchor may then be fixed securely by supplying concrete or the like down the coiled tubing and into the hole. The mooring apparatus includes a buoy, releasable by remote signals. Also disclosed is a mooring apparatus which anchors itself by changing it's profile in the soil, by, for example, inflating, or opening up like an umbrella.
