Bluewater Energy Services, located in Hoofddorp, the Netherlands, has placed an order with Siemens Industry Automation Division for supplying a pump skid that features Brise dissolved gas flotation (DGF) technology. The skid is part of the produced water system on the Glas Dowr, which is a floating production storage and offloading unit (FPSO). The FPSO has been relocated to the Kitan field in the Joint Petroleum Development Area, offshore East Timor, Australia.

The Brise DGF pump technology from Siemens has been installed on an existing degassing tank for the upgrade to the produced water treatment plant of the Glas Dowr. The Brise DGF technology helps optimize gas bubble size for the flotation process, which in turn yields improved capacity and efficiencies. It also saves required chemicals and offers end-users maximum flexibility because the bubble sizes can be instantly adjusted to meet requirements.

The DGF technology can be used with new flotation units, existing systems, and as part of an upgrade or retrofit. Siemens has completed more than 200 retrofits/upgrades successfully on a wide range of Siemens equipment as well as that of third parties - equipment such as skimmers, degassers and mechanical flotation tanks. Using the DGF technology can result in substantial savings for end-users due to improved efficiency of existing equipment. Depending on how complex the equipment is the necessary adjustments can be made and recommissioning done within a few days. This makes the Siemens technology a more cost- and time-effective alternative to completely replacing the system with new equipment.
