ABB and Statoil to develop deepwater subsea power and control technologies
$100 million R&D program enabling future ultra-deep water and remote subsea factories
Transformers are one of the components that need to be equipped to withstand the pressure of standing on the seabed for several decades. This is from the testing in Finland of a transformer for the Norwegian Continental Shelf from an earlier project.The five year program is pivotal to the development of technologies required to power and control large-scale subsea pumping and gas-compression projects planned for the Norwegian continental shelf, the Gulf of Mexico and other places around the world. Subsea pumping and gas compression contribute to improved utilization of oil and gas resources through greater recovery rates, reduced production costs and the further development of deep water production.
The JIP will provide solutions for transmission of electrical power up to 100 megawatts (MW) over a distance of 600 kilometers (km) and to depths of up to 3,000 meters (m). This is important for the development of remote oil and gas fields located far from other infrastructure.
ABB is manufacturing its own semiconductors, which is an important component of the electrical system needed to power subsea installation with reliable power.This subsea electric power distribution technology enables several electric loads, such as pumps and compressors, to be supplied through a single power cable. This will reduce investment costs significantly compared to existing solutions using one cable for each individual load. The new technology, for example, will make savings of more than $500 million, if eight loads are linked through a single cable over a distance of 200 km from other infrastructure.
To ensure compact and reliable solutions, the equipment will be enclosed in liquid filled, pressure compensated tanks, with components tested extensively under the full pressure they will experience at the target water depth. The program entails material and component qualification, detailed design and full-scale testing of a 36 kilovolt (kV) distribution unit and two variable speed drives for pump and gas-compressor applications, respectively.
ABB (www.abb.com) is a leader in power and automation technologies that enable utility and industry customers to improve their performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 145,000 people.
