<p>1,272,491. Subaqueous structures. COMPAGNIE FRANCAISE DES PETROLES S.A. 28 May, 1969 [26 Sept., 1968], No. 27079/69. Heading E1H. [Also in Division F2] In a subaqueous installation for separating gas and oil flowing from an underwater well envelopes 1, 2 house a separator and monitoring and control apparatus, respectively, the envelope 2 together with the apparatus therein being removable to facilitate servicing of said apparatus above the water. Connection between ducts 4, 11..15 and corresponding ducts in the envelope 2 is effected by a conic member 8 on said envelope engaging with a similarly shaped surface 6 on a fixed member 3. Openings in the surface 6 at the ends of the ducts are in register with similar openings in the member 8 when the envelope 2 is in situ, Valves 16, 17, 18 are shut when the envelope 2 is removed. The valves may be replaced by rotatable sleeves 21, 47, Fig. 2, in fixed members 24, 28, each of which is similar to the member 3. An envelope 26 similar to the envelope 2 can be mounted on either of the fixed members so as to allow rapid exchange of identical sets of monitoring and control apparatus, a separate envelope being provided for each set of apparatus. A rotatable sleeve 46 may be provided on the conic member 45 to obviate flooding of the apparatus when the envelope 26 is removed. Each of the sleeves has a set of orifices therein which by rotation of the sleeve can be aligned with the openings in the corresponding member. The openings can thus be obturated by altering the positions of the sleeves. The sleeves can be fixed by bolts 25, 48 and to permit lubrication thereof may be separated to some extent from the adjacent member while being rotated. Lubrication is provided by oil in one of the ducts. Mechanism (not shown) is provided for manual or automatic lifting and rotation of the sleeves.</p> |
