The World’s Largest Injection Pumps


Sulzer Pumps has been awarded an order to supply four seawater injection pumps that will be the largest ever built. The pumps, to be supplied to the Azerbaijan International Operating Company (AIOC) for installation on their Compression and Water Injection (C&WP) platform for the Azeri Development Project in the Azerbaijan sector of the Caspian Sea, are each rated at approximately 26 MW absorbed power.

This is some 50% greater power than the previous record, also set by Sulzer. The pumps will be driven at 4800 rpm by Rolls Royce RB211 gas turbines. A “low flow” pump cartridge fully interchangeable with the main pumps will also be supplied to meet the early phase injection requirements. All pumps will be string tested at full speed, full load driven by the gas turbines at Sulzer Pumps test facility in Leeds, UK, where the pumps will also be built.

Delivery is scheduled for April to July 2004 and is to meet stringent weather window requirements for transport to the Caspian.

This latest order follows on from the success of Sulzer Pumps in building the world’s high-pressure centrifugal injection pumps for installation on the bp operated Thunder Horse project in the Gulf of Mexico.
