Uninterruptible power supply (UPS) is a key device in the electrical system on the offshore oil platform. It supplies the key loads such as the communication equipment, instrument control, electric protection, and control panels or workstation for the key machines when the normal and the emergency power supplies both fail. We deal with the calculating method for sizing of UPS and perform engineering calculation on the UPS sizing of a certain offshore platform. It is proved that the calculating method is simple and convenient, and can be used for the electrical design of other offshore oil platforms.

Key words: offshore platform, power supply system, uninterruptible power supply, key loads, calculation for sizing
