ROV installed suction piles

InactiveUS6719496B1Anchor handling/lashingAnchorsSupporting systemSelf penetration
A method is disclosed for deploying a suction pile anchor in which flood valves are opened on the top of a suction pile and the suction pile anchor is off loaded from the anchor boat and lowered it to the sea floor. The suction pile anchor is set down and the rate of feed is adjusted to match the rate of self-penetration. An ROV with pump capability closes the flood valves on the top of the suction pile and attaches to the pumping port of the suction pile. The pump of the ROV operates to draw down the suction pile to full depth and brings the first load line connection and the attached first end of the load line well below the mudline while the second load connection at the second end of the load line is supported above the mudline. The ROV disconnects from the pump port and connects a mooring line to second the load connection. Another aspect of the present invention is a suction pile system having a suction pile with an ROV compatible pressure port and a flood valve at the top. A load support system includes a first load connection on the side of the suction pile with a load line connected to the first load connection. A second, ROV accessible load connection is provided at the distal end of the load line.

A mooring system for securing a floating vessel to the sea floor comprises a plurality of mooring legs, at least one of which includes separate first and second mooring lines. The first mooring line comprises a first end which is connected to the vessel and the second mooring line comprises a first end which is secured to the sea floor. The mooring system also comprises a connection and tensioning device which includes a body, a bore which extends through the body, a chain stopper for adjustably securing the first mooring line to the body, and a connector for connecting a second end of the second mooring line to the body. In use, a second end of the first mooring line is inserted into the bore and the first mooring line is pulled through the bore while the body is subject to an opposing pulling force. Once the first mooring line is pulled through the bore a desired distance, the chain stopper maintains the first mooring line in position relative to the body to thereby secure the vessel to the sea floor.

Anchor monitoring system

A system wherein a vessel (12) is moored by catenary mooring lines (14, 15, 16) that include polymer cable lengths (30) that can stretch under tension, which indicates the amount of polymer stretching. In the absence of polymer line stretching, a measured actual drift or excursion of the vessel from its initial position (as determined by a GPS system) would result in a predetermined nonstretch inclination (graph 50) of the top (42) of a first mooring line (14) from the horizontal. If the inclination is greater than the predicted nonstretch inclination, this indicates that the polymer line has stretched, with the amount of stretch indicated by the increase in inclination over the predicted nonstretch inclination.
