I watched a video by pilot (ships pilot) yesterday where he reviewed the NTSBs report on the BB content. He said the indications are that a total electrical power failure happened, the way the BB is powered, it' has battery backup and kept recording voice and noises on the bridge, but not data. HE said this makes sense, as the recorder and mics are on battery backup but the sensors all over the ship are powered directly with no battery backup.

He went on to explain that many ships run their standby generators when in or near port, tho there is no law to do so. This ship didn't and he also thinks the emergency generator(s) may be a maintenance issue. He said the company will try to blame the crew, but if the emergency generator(s) were not available, the liability will be on the company.

According to him: CLEARLY, the standby-emergency generator(s) were not working. I don't see how the company can't be held liable in such a case.
