HVDC Light can be used to deliver power both to and from offshore platforms.
Power to platform
Traditionally, all auxiliary power used on oil and gas production platforms has been generated locally. A large number of investigations have been made over the years to feed power from land using classic HVDC. But none of these has materialized because of the weight and size of the converter equipment, and in particular the synchronous compensators that would have been necessary
But with HVDC Light® these difficulties are overcome: the converter is smaller and weighs much less, there is no need for a synchronous compensator, and the power range is better adapted to the needs of the platform. And the HVDC Light extruded cable is much less expensive than a traditional mass impregnated submarine HVDC cable.
For a group of platforms the converter station can be located on one and power can be distributed to the others via AC cables, or DC power can be distributed to several platforms in a multiterminal arrangement.
Offshore power plants
The obvious advantages with HVDC Light® of course applies also for offshore power plants that generate power from e.g. excess gas on oil platforms, that would otherwise be flared.
