Marginal specialist branches out from multiphase to subsea separation
Typical Framo multiphase flow meter [17,558 bytes]. Framo Engineering has emerged as a world leader in marginal field technology. The company is engaged in several major projects which offer significant potential for such developments, ranging from multiphase boosting and flow meters to swivel technology and subsea separation systems. With field developments moving to ever more remote locations, deeper waters and further from existing infrastructure, the need to add pressure energy to the

FLOATING PRODUCTION Semisubmersible conversion in position at Liuhua 11-1
Bill Hunter, Lindsay Clark Reading & Bates The Liuhua 11-1 Field development consists of the Nanhai Tiao Zhan linked to an FPSO and transport tanker. The semisubmersible FPS Nanhai Tiao Zhan is a major component of the Liuhua 11-1 development system. The unit is a modified drilling semisubmersible, specially converted to support the subsea production well cluster over which it is permanently moored. The design and conversion was a major project entailing specialized engineering and procurement

SUBSEA TECHNOLOGY Diverless flowline pull-in to well developed
The attachment of flowlines subsea has required divers on the seabed or surface support vessels with winches and remotely operated vehicles to pull together and mate the connections. Both methods were costly, and as water depths increased beyond diver depths, the outlays began to occupy a large segment of the installation allocation. Also, the ideal surface support vessels were not always available.

ADVANCED TECHNOLOGY
Leonard LeBlanc Houston The welfare of the US gas industry now seems directly coupled to the presence or absence of El Niño (more properly El Niño-Southern Oscillation cycle), the periodic warm offshore currents that blow into South America from the west, in turn keeping the North American continent unduly warm over the winter months. The 1995-1996 winter season is the first normal winter in some years, free of all effects from El Niño, and gas prices have been higher than in

FRANCE Surface - sea bottom data link shuts out noise interference
The Elise 3 plough with ORCA's MATS modem on the starboard bow. Deepwater subsea developments are demanding installation of increasingly autonomous seabed structures. This trend was the basis for a new generation of underwater acoustic products from Brest-based ORCA Instrumen-tation. The latest of these, called MATS, is being offered as a reliable and cost-effective alternative to use of underwater cables.

Advanced Electronics New developments in marine electronics . . .
A minimum shift keying receiver that uses differential global positioning system data transmissions from marine radio beacons has been developed by Trimble Navigation of Sunnyvale, California (US) for portable operations. The system is ideal for surveying, dredging operations, resource management, and operations that are conducted in transition zones where precise positioning is required. The system, known as ProBeacon, has an accuracy of less than one meter when using a Trimble 4000 Maxwell
