Title: Marine risers and buoyancy means therefor
IPC: F16L1/24
Filed: 1973-11-20
Abstract: 1471540 Buoyancy units SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 14 May 1974 [20 Nov 1973] 53724/73 Heading B7A [Also in Division E1] A sectional marine riser extending, e.g. between an underwater wellhead and a floating drilling vessel or between a well conductor casing cemented in the sea bed and a submerged wellhead, has at least one of its sections fitted with buoyancy means including a number of stiff-walled, fluid-tight buoyancy tubes arranged around the exterior of the riser section(s). The tubes may be in the form of hollow rings or they may be wrapped spirally around the riser section(s), the tubes in each case being confined between flanges, the upper of which transmits the buoyancy force of the tubes to the respective riser section, and optionally also being enclosed in a perforate jacket. As a further alternative, the tubes 32 (Figs. 5 and 6) can extend axially of the associated riser section and can be housed in a perforate one-piece or sectional jacket 33, the abutting joint faces 41, 42 in the latter case suitably being recessed to accommodate choke and kill lines running along the riser. The tubes may be arranged in the jacket in circumferentially-extending rows, the tubes typically then being of different sizes in different rows. Instead of being perforate, the jacket may be flexible or have membranes in its walls and be filled with a liquid, grease or rubber which transmits ambient hydrostatic pressure to the tubes, the liquid filling optionally being contained in the pores of an open-cell elastic foam present in the jacket. In another case, the jacket can be omitted and the tubes held together by a rubber composition filling the spaces between the tubes. The tubes may be of lightweight metal, e.g. Mg or Al, or of reinforced or unreinforced plastics, e.g. epoxy resin, polyesters, p.v.c. or a polyolefin, suitable reinforcement being glass or carbon fibres. In one particular construction, the tube walls have fibre-reinforced inner and outer layers and an intermediate region in which hollow gas-filled resin spheres are incorporated to reduce weight, there being more reinforcing fibres in the inner layer than in the outer layer. The tubes contain gas at sub-atmospheric, atmospheric or superatmospheric pressure and may also contain a foam filling capable of increasing the collapse strength, and the wall thickness of the tubes suitably varies according to the depth at which the tubes will be located in use. The buoyancy means in each case can be clamped or bonded to the respective riser section.

Abstract: 1377977 Vehicle control MESSERSCHMITT-BOLKOW-BLOHM GmbH 22 Nov 1971 [2 Dec 1970] 54133/71 Heading B7N [Also in Division H4] In an arrangement for controlling the spacing of two vehicles moving on a common path to a preselected value the required speed of the second vehicle is modified by a factor value xd = distance between the vehicles; a = constant; V 2s  = required speed for second vehicle; V 1I  = actual speed of first vehicle. Each vehicle carries a transmitter 1 and receiver 2, operating at 500 MHz, which are coupled to a VHF transmission line 3 extending along the vehicle track and the coupling leads 7, 8, to the conductor 20 of the line are joined by a capacitor which resonates with the conductor inductance to form a blocking circuit which allows each vehicle to transmit only to its rear and receive from ahead. Unit 15 supplies voltage V 1I  which is a tunction of actual vehicle speed and this is applied via voltage frequency converter 13 to unit 14 which frequency modulates the transmitter 1 with the actual speed information and this signal is transmitted via line 3 to a vehicle to the rear. In this latter vehicle the signal having an amplitude which is a function of line loss between vehicles is received in receiver 2 and applied via a frequency demodulation circuit 17 and frequency voltage converter 18 to subtract circuit 4 which is also supplied with the value of speed requested V 2S  from store 24. The subtract circuit supplies an output (V 2S  - V 1I ). The output from the receiver is also supplied to rectifier 23 which is arranged to provide the output e<SP>-axd</SP> where a is the line attenuator constant and xd is the distance between the vehicles. This is applied with the output from the subtract unit 4 to multiply unit 5 which provides the factor V 2F . This factor is used in unit 6 to modify the required value of speed V 2F  stored in unit 24 and the modified value is used in speed regulator 22 to control the vehicle speed. The conductor 19 of the transmission line can be the neutral traction supply return circuit and the conductor 20 can be of iron.

In another embodiment, the rod 3 is connected by a crank to the rocker arm 5, the crank being driven by a ball-drive from the motor 13. The joints B, C, E at the ends of the rod are in the form of universal joints.

Additional pressure is also applied by a central disc 11 with cross-ribs 15. This disc is pressed downwardly by oil pressure rams 12, 13 and is rotated through gearing 18, 19 by a motor 17. The blocks may be cylindrical or slightly tapered or they may be of square, triangular or semicircular cross-section. Casing 5 is movable horizontally along rails 28 from a charging to a pressing position.
