Thursday evening we found ourselves sitting in the dark for a few hours. The generator on our support buoy (LSB) shut down due to a fuel problem. No warning, just a switch to emergency lights. When something like this happens the topside support team responds immediately. At 2000 hours last night, just before the shift change our mid-shift team came out, re-started the generator, and restored power. This might not seem like a big deal, but when you rely on electrical power from a source that you don't have access to (50 feet above us on the surface), it's a real big deal. So I want to say, THANK YOU, to the topside guys who make it possible for us to work underwater.
