Variable Speed Drive Modules
OEG Offshore design, manufacture, and supply high specification variable speed drive (VSD) and variable frequency drive (VFD) control modules for the oil and gas and offshore wind farm sectors.
Our project team has extensive experience in designing bespoke modular units and producing larger cabins up to 200 tonnes in split-module formats designed for easy on-site integration and commissioning of customers' equipment. OEG has developed an international reputation for quality, safety and providing cost-effective offshore modular solutions for our global customers and particularly in this specialist area of high specification VSD modules.
We have also designed and manufactured modules with specialist fire ratings from A0, A60, H0, H60, H120, J30 fire classification incorporating blast protection from 100 mb up to 1000 mb in order to meet customers specific installation requirements.
All offshore modules are expertly outfitted including the full integration of your free-issue equipment.
