1,113,914. Laying pipes. SOC. D'ETUDE DU TRANSPORT ET DE LA VALORISATION DES GAZ NATURELS DU SAHARA " S.E.G.A.N.S." 25 Aug., 1965 [1 Sept., 1964; 11 Aug., 1965], No. 36456/65. Heading F2P. A conduit c is laid under water by traction exerted thereon and is maintained at a distance above the bed F by ballast of weight and form calculated to resist the effect of cross currents. The ballast comprises a pair of cables a 2- a 2 , spaced apart side by side along the bed F, which at intervals are clamped in one of a pair of parallel split channels, each longitudinally along the bottom of one of the two splayed feet 2 which support short lengths of guide tube g 1 , g 2 , g 3 &c. The tubes g 1 &c. are split lengthwise along the bottom so that they can be threaded in sequence g 6 , g 5 , g 4 &c. which extends from a shoreward hold fast to a lighter N. Set in the top of each guide is a pair of pulley sheaves in tandem over which the cable a 1 can freely run. The guide tubes are threaded on to the cable c, they are let out from the lighter by pulling at t 2 on the cables a 2- a 2 . When a length of the ballast cables has been laid the cable a 1 is transferred from the hold fast to the end of the conduit c which is then winched out at t 1 through the guides g. The lighter is then winched further out on the cables a 3 -a 3 (which may be continuous with a 2 -a 2 and the laying sequence repeated exactly or with a variant which is explained in the Specification.
