A joint industry project on subsea electrical power standardization has published an international industry standard on the design, testing, and qualification of subsea power transformers. The standard seeks to reduce subsea field development costs by creating more uniformity.
Operators involved in the effort were Statoil ASA, Royal Dutch Shell PLC, Total SA, Petroleo Brasileiro SA, Chevron Corp., ExxonMobil Corp., and Woodside Petroleum Ltd.
Subsea power transformers reduce high voltage to levels that can be used by pumps, water injectors, and gas compressors.
“The need for transparency, collaboration, and standardization between operators, contractors, and suppliers is greater than ever before,” said Michael Sequeira, deepwater practice leader at OTM Consulting. “The growing complexity and cost of advanced subsea systems dictates the need for cross-industry collaboration.”
