In “We concluded there was an unmet market for subsea service, the VSDs could be put in parallel to provide higher power distribution, as long as we successfully address the power. Additionally, low voltage local distribution could be system cost and complexity,” he says. “Those were the main done using some of the subsea power grid elements. problems preventing customers from using subsea process-
