It's not very often that a 412 is lost. Surprised also that the pilot was the only person on board, I thought ExxonMobil contracts now called for 2-pilot ops on all flights whether passengers were being carried or not?

As reported, the helicopter crashed inside an ExxonMobil onshore facility, and that rain was falling heavily in the area at the time of the accident. In the link below, Bristow has now named the pilot (a Spanish resident on a UK passport).
