Abstract
In a system for anchoring a floating vessel which is anchored only by parallel and essentially vertical conduits the anchoring load is carried by units of concentric pipes including an outer riser pipe 24 and inner strings of casing 78, 80. Drilling wells and/or production of oil and gas or like these casings. Means are provided for transmitting the tension of the inner casing strings 78, 80 to the floating vessel through the upper end of the outer riser pipe 24. Means are also provided to prevent excessive buildup of stresses in the upper end of the inner casing due to the bending caused by the excursion caused by the waves, the wind, and the current. <IMAGE>
