Where DDS Technology Helps Extend the Search

The offshore platform is an excellent picture of a rule that has guided oil exploration since the first successful well was drilled in 1859: you’ve got to go to where the oil is because it won’t come to you. In recent years, the offshore quest has moved drilling farther and farther from shore.  Whether you’re deep-water drilling in the North Sea or pumping multiple wells within sight of land, DDS technology can facilitate the process.

Traditionally, electricity has been generated offshore by coupling turbines with low fixed speed (1800/3600 rpm) generators via a gearbox. DDS high speed electrical machines are excellent choices for these generating applications. They are 20% the weight and size of conventional solutions and run at 10-20% higher efficiencies. As an added bonus, they do not require a gearbox.  Consider an 8MW turbine generator application, utilizing a traditional generator and gear box, the total weight is approximately 50,000 lbs. The same 8 MW generator utilizing a DDS generator and no gear box will weigh approximately 10,000 lbs! Similar weight and size reductions can be obtained by using DDS electrical machines as prime movers for compressor and blower applications. When paired with DDS’ four quadrant power electronics, the turbine will be started seamlessly and provide clean, regulated power.

The use of DDS products for these motor and generator applications could save platform operators tens of millions of dollars in platform construction, equipment installation and running costs.
