Hello KP
Kind of a long question. I am indeed suggesting that they managed to start the main engine few seconds after they restored power to the main switchboard (MSB) and the telltale indication is the heavy black smoke from the largest exhaust outlet in the funnel.
I am also of the opinion that the emergency diesel gen (EDG) started and continued to run powering the ESB right upto the point of impact. I think the running lights were only noticed when the main power came on about a minute after the initial blackout.
PS:
a. I am a new user and as such looks like I am restricted to only 3 replies … so I may not be able to reply again, and the suggested work around is to edit one of my posts … response will go into the proverbial black hole. Happened on the previous thread when I tried to respond to Mr 244.
b. By way of a short introduction as to my credentials, I am a mechanical engineer and a licensed Chief engineer. Have about 12 years of sailing experience in the 80’s with one of the largest shipping companies. Engine types are Sulzer RNDs, B&W GF and GB engines. Container and some tankers. Came ashore and management experience in the US includes container ships with Sulzer RTAs and MAN B&W MC engines. Left for different challenge to the O&G industry 15 years ago with one of the large companies who are designers and operators of FPSOs. Retired last year.
Thanks.
