Rebecca, not being an engineer, wasn’t one to scan over things and understand what was what. So seeing the pre and post incident listings for the primary coil drive, she frowned. “Is this anything to look at?” She pointed to the differences in the listing there and how far down the list it had been placed. “I noticed it because of the pre and post readings from the last mission. Was it normal to have this level of fluctuations in that short a time?”
She was making notes on the side to use in the sim for the holodeck. “Perhaps in a cascade, butterfly affect?”
“Hmmm…” Koria said as she looked at the information on the primary driver coil Rebecca was pointing at. Moving to one side, she brought up the diagnostic data from the driver coil on a larger monitor.
“There have been some fluctuations in the primary driver coil for the engine since the last mission, but everything has been within normal operating parameters. I would have had a team look at it eventually, we’ve just had larger problems to fix first…” she said as she looked at the data more closely. As it led up to the explosion there a sudden spike in the power and fuel consumption of the system, right before the engine exploded.
“Well I’ll be, I think you found the culprit. It looks like the primary coil had a momentary failure. Normally the secondary systems would take over, which the computer tried to do, but there must have been some residual damage. At the same time, because of the sudden increase in mass from the coil failure, it looks like the fuel injection system got locked in full open, which eventually led the system to get over pressurized and explode.”
Which meant in the end it would have been preventable, if she had caught it sooner. Yes it might have been a perfect storm situation, but if she had taken the time to look at the engine sub-systems, she might have noticed the fluctuations in time to have someone take a look at them. As the thought ran through her head, Koria leaned back against the console, her shoulders falling.
“It could have been prevented, if only I had noticed the fluctuations in the system.”

Rebecca frowned. “Lieutenant. Didn’t you just say they were in normal parameters? Do you check everything all the time if it appears to be ok?” She leaned back on the console beside the Chief. “I wouldn’t take it to heart. It appears it was a little bit of a lot of things. I imagine you don’t have the man power to track down every little thing that shows up on the ‘we’re ok till you wanna look at us’ list. Do you?” She lightly touched the woman’s arm then dropped it not wanting to seem overly familiar. “So I wouldn’t beat yourself up over it.” She hoped her smile would help ease the guilt the woman was feeling.
“I still should have seen it. It might have been in normal parameters, but there was still a fluctuation. It warranted being looked at still. It could have been prevented,” Koria said grumbling to herself. She knew that Rebecca was trying to cheer her up, but it would still take a moment for her to work through it.
Taking a deep breath, she ran her hands through her hair before standing back up straight. “Thanks.” She was still going to bear herself up over it more later on. But for now they have a job to do.
“At least we have a theory so far on what happened. The question is, was it just the perfect storm of failures? Or was there another factor?”
Lt Sutret - CE
Rebecca smiled. “No need to thank me. We are doing this together. You would have seen it, I’m sure. As to if it was the cause or not…” she started to run the sim of the accident. “Let’s see what happens with that as a factor and without. If it happens without it as a factor, we know it was an additive, but not the cause.” She grinned at Sutret once more. “Right?” Running the sim she waited to see if the computer would spit out that it was part of the issue, or a non factor that was just out of place.
Simulations run one after the other would be .. inconclusive.
Some that were run purely on the factors included showed a 62% chance of occurring again, while removing that failure indicated a 84% chance of it not occurring.
After a number of simulations it appeared that there was a chance of it occurring but not always, as well as with a factor that within some of the simulations the computer caught the failure and managed to halt the effects before anything ‘critical’ occurred.
Koria looked over the simulations. “So some of the time the computer found the issue in advance, sometimes it did not. It almost sounds like it was either a perfect storm of problems, or there was outside influence. As much as I’d like for there to have been outside influence that caused my engine to blow up, I know that would cause all sorts of other problems for us.”

Bekka shook her head. “So it was random. I don’t think we can learn anything from running the sim more times, honestly. The perfect storm, as you call it, seems to be the culprit. I would recommend we get as many of the ‘suspect’ specs up and back into areas where they aren’t on this list of possibilities. Then maybe things won’t cascade and fail again. How can I help?”
She was curious why there was such an even chance of it happening or not happening again. Sometimes the computer caught, sometimes it didn’t. Maybe a cumulation of all the ‘slightly off’ readings were what caused it to happen and not just one of the anomalous readings. Getting everything back to where it optimally should be should be what cures the ship of what ails it.
