UPS on offshore oil platform

A milestone success story for ABB uninterruptible power supplies.

In 2012, ABB, together with their business partners ADC Power Concept Sdn Bhd, completed a very significant order with Petronas, Malaysia, for delivery of uninterruptible power supplies to an offshore oil platform. The delivery project was completed in October 2012.

Assurance of power supply is important in many industrial settings, but, on an offshore oil platform, it is absolutely crucial. For this reason, ABB’s client, Petronas, Malaysia, sought an alternative to the less reliable traditional, industrial-grade, floor-standing UPS systems. The new UPS should be field-proven, highly customizable  and reliable. It should also eliminate switchover downtime.

Because the offshore environment can be very harsh and remote, the UPS also had to be rugged, with high availability and reliability, and repair and maintenance should be simply accomplished by non-experts. rugged, with high availability and reliability, and repair and maintenance should be simply accomplished by non-experts.

For these reasons, and after extensive product comparisons, the client chose one set of ABB 4 x 40kVA DPA modular hot-swappable UPSs and two sets of ABB 3 x 30kVA DPA modular hot-swappable UPSs. The delivery included an external input transformer, an external battery charger, an IP 31 protected rating cabinet and the capability of charging a NICD battery set, to provide a long back-up time.

Comprehensive supply, installation, testing and commissioning was included in the order.

As this is a completely new product configuration with no proven record on offshore platforms, a gradual product assessment policy was pursued: A few systems were installed in a Petronas plant and in a crude oil storage facility so that an assessment based on the onshore environment could be carried out.  Also, a detailed factory audit was carried out at ABB Newave, Switzerland prior to the confirmation of the order.
