The fuel line break was on the Triumph, not the Dream. Triumph was out to sea when it happened. For the Dream they never lost normal electrical power, just emergency power, which was being tested. Apparently the emergency generator fault caused some breaker trips that had to be tested before they could be re-energized with normal ship's power. Thus, even if they were hooked up to shore power it wouldn't have mattered. The breakers were still off-line.
