@SaneIT, let's hope we've come a long way in the last three years in not only the trust placed in sensor data but in our ability to make sense of it. Deepwater decision making, especially with disasters like that hanging over head, have to be daunting irregardless of what the data or the experience is pointing people to.

I have to agree that not many companies out there are ready to act immediately on any data.  If we look at issues deep under water for an example we just have to look back at the Deepwater Horizon oil rig explosion we had in the Gulf of Mexico a couple years ago.  There were warning signs but they were partially ignored because the sensors weren't trusted.  From the investigation "The report found that on 20 April 2010, managers misread pressure data and gave their approval for rig workers to replace drilling fluid in the well with seawater, which was not heavy enough to prevent gas that had been leaking into the well from firing up the pipe to the rig, causing the explosion."

SRS1, I suppose we could consider it a bit ironic, then, that the work Tom and his team is doing is aimed at getting ahead of things that would affect the performance of Shell's deepwater assets via predictive maintenance. Mind you, Tom & I never talked about the analysis of sensor data for safety purposes. I don't know if that's something that comes under his purview.

Monitoring sensors in the ocean are a great idea but if any situation should arise that sends incorrect information due to faulty sensors, we might not know until it is simply too late.

I'll add this. At this point, I'd rate the interactive capability actually more than the real-time  data feed as more important. The interactivity can deliver instant insight, and while getting that instant insight on real-time data is great, I'm not sure too many organizations are yet prepared to act on it in real-time. Would you agree?

SaneIT, so... the knowing you can't easily get to the sensor or manually check the environment looms over the data collection process regardless of whether or not it's going smoothly at the time. That actually seems a reasonable cause of doubt, which hopefully could over time be eased by positive results. I didn't get a chance to ask Tom what happens when a sensor fails, or about the lifespan of the sensors and the equipment they're on. He did say that he did wish they'd put more sensors out there than they did. But then again, that would have come at a cost and there's always that to weigh.

I think it's a more general problem but but that having them at the bottom of the ocean makes verifying the data a little more complex.  Having spent time working in a chemical plant I can say that sensors go bad without warning but in some cases it is very easy to tell that the sensor is giving a bad reading.  For instance say you have a sensor monitoring water pressure in a long pipe line.  One sensor is showing a much lower pressure than sensors on either side of it 1/2 a mile a way are.  It's pretty easy to drive out to where the sensor is located and walk the pipeline to see if any fittings are leaking.  Or you're monitoring temperature and humidity of a room and one day the humidity reading spikes for an unknown reason so you walk in with a hand held unit and check the temp and humidity.  I may be wrong here but I don't think the checks are that easy at the bottom of the ocean so they face a unique problem.

@ Lyndon Adding interactive visualization to the mix would give amazing results. Think of the endless scenarios you could potentially generate. I can't wait to hear more about what is currently available in this area.

Visualization really gives a new meaning to numbers. When you are just looking at numbers your ability to recognize trends and patterns maybe limited, since then the view point will most likely be based on logic alone. But visualization adds a new dimension and enables us to instantly recognize patterns that could have taken much longer to identify. If you add real-time visualization to the mix you will have a much faster response time. A negative result pattern could be instantly corrected.


 

I agree -- pattern/trend recognition is a major benefit. I also agree with your point about real-time visualization, and I'd add interactive visualization -- the ability to input alternative assumptions, scenarios, etc. and get an immediate visualization feedback of the effect.

@Phoenix, exactly! I'd love to see a study or statistics on the difference in time to decision-making before and after an organization begins using real-time data visualization to deliver analytics.

It Pays to Keep Insurance Fraud in Check
While 97% of insurers say that insurance fraud has increased or remained the same in the past two years, most of those companies report benefits from anti-fraud technology in limiting the impact of fraud, including higher quality referrals, the ability to uncover organized fraud, and improve efficiency for investigators.
