OTC 2012: Magnetic bearings, new compression concept coming from Dresser-Rand

Offshore staff

HOUSTON –Dresser-Rand will emphasize efficiency and customization of its rotating equipment at OTC this year.

First up is the introduction of several magnetic bearings that integrate the control system with the actual bearing structure for use in compressors, pumps, electric motors, blowers, and fans. With a variety of frame sizes in both radial and thrust configurations, Dresser-Rand says these magnetic bearings eliminate the need for lubrication, offer no mechanical wear or friction, and can be tailored to optimize performance. These bearings also can reduce footprint and weight to save capex on platform and FPSO construction.

Another item for OTC is a new compression concept called the DATUM I Integrated Compression System (ICS). This system is engineered with centrifugal separator technology incorporated on the compressor rotor for efficiency and compactness.

The DATUM ICS features centrifugal separation technology; a high-speed, close-coupled, gas-cooled motor; dedicated unit controls; process coolers; valves; instrumentation; and interconnecting piping in a compact module.

The DATUM ICS uses centrifugal force to separate oil, gas, and water from the flow, says Dresser-Rand, and this protects the compression flow-path from potential damage by removing free liquids from the gas stream. When compared to traditional compression modules, DATUM ICS takes up 50% less space and weighs 50% less, according to Dresser-Rand.
