Explosion proof certified Solar/Wind Hybrid Power System

Shell (UK) in cooperation with Tss4U (NL) developed the solar/wind hybrid power system for
the “Trident” platforms.
After a pilot project, systems for the first two Trident platforms were applied in June 2005.

The development of the Shell ‘Trident’ platform (Fig. 1) concept has reduced the platform
facilities and utilities to the bare necessity, which also resulted in a substantial decrease in
electrical power demand. The power demand of a Trident platform is now limited to a total
continuous load of approximately 1.2 kW. This power was to date supplied by subsea cable.

The solar/wind hybrid renewable energy (RE) project was initiated to explore the potential for
future Capex reductions. The installed cost for the hybrid renewable power supply is about
£200k, compared with about £1–2m for a subsea cable.
In this project, solar panels and wind turbines are chosen to provide the renewable energy
due to the maturity and proven technology. The other reason is the complementary output
provided by these two forms of energy under seasonal variation in weather conditions. The
solar panel plays a major role in recharging the battery in the summer months when the
output from the wind turbine is at the lowest and vice versa during the winter months.

The scope of the solar/wind hybrid power system for a continuous 1.2 kW power demand in
a hazardous area zone 1 offshore environment consists of:
   • Two 2.5 kW Wind Turbines
   • 50 m2 Solar Panels
   • 7000 Ah Battery storage
   • Associated charge control and data monitoring systems

The power/control package will be installed on the upper deck of the platform and the
output/monitoring package will be installed at a lower deck (Fig. 3)

To minimize offshore installation/commissioning work, all equipment on the upper deck is
installed on skid frames which can be lifted totally from the platform for eventual exchange
with a spare system. All the equipment performance data is stored in a data-logger and can
be viewed onshore via Ethernet/telecom. To minimize visits to the platform the data-logger
can be checked for past and actual performance of the RE system in order to schedule the
required maintenance on the platform.

Description: Hybrid Power technology is actually configured by the integrated chipset graphics card to support the technology in the drive and the operating system under the control of the time when the system load using only integrated graphics chip to reduce power consumption, and when full time work load by the integrated graphics with discrete graphics cards to further enhance the efficiency of this technique one can reduce system power consumption, especially those who can benefit from a system with discrete graphics, but can also enhance the system to some extent integrated graphics performance.
