Transformers for offshore oil, gas

Hitachi Energy is a leading global manufacturer of liquid-filled and dry-type transformers specifically designed to meet the requirements of the oil and gas industry in offshore applications.

To ensure optimum performance at your offshore site, you must know your equipment is perfectly functioning.  Whether a floating production unit or a subsea unit, Hitachi Energy can provide environmentally safe and reliable transformers that are resilient to the harsh marine environment. 

Dry-type technology offers entirely oil-free products. A minimum of other flammable materials are used in transformer manufacturing to drastically reduce the risk of fire, thus increasing the security for offshore operators and avoiding contamination in the transformer’s surroundings.  The dry technology also offers maximum strength against thermal and mechanical stresses to withstand the harsh environment in the oil and gas complex.

Hitachi Energy has a full range of subsea transformers designed up to 3000 meters of depth. The high-pressure subsea environment presents unique challenges to seabed-based compression and production systems. Hitachi Energy subsea systems' designs can be wet and dry terminations. Our first production unit from 1998 is still in service.
