There were also discussions around innovation that would be more relevant to utility markets such as smart metering, leak detection, pressure regulation, water quality monitoring and more.

Sources close to the investigation tell Forbes that Transocean engineers had last checked the blowout preventer 10 days before the rig explosion, and that BP believes the device suffered a leak of hydraulic pressure, preventing it from being able to shut the well.
During the Russian side of the pre-sleep debriefing on Sunday, Mission Control in Moscow congratulated Kaleri for fixing the leak and stabilizing air pressure.
As a result, the "signature" of the pressure drop was very garbled, and sources told MSNBC.com that some space engineers argued there was no increased leak at all, but merely pressure changes caused by these other factors.
At its worst, the pressure drop corresponded to a leak five times the normal rate, but by late last week it was only twice the normal rate.
Chevron's admission that a spill from a high-pressure Shetland oil well could leak at a higher rate than BP's Macondo well (1, 500 metres below the surface) didn't help.

The plaintiffs claim that BP put profits before safety, and the oil leak happened because drilling was rushed due to pressure from management to cut costs.

The pressure in the capped-off well could blow a new hole in it, letting oil and gas leak out through the seabed.
In order to determine the location of the leak, the crew had been sealing off small peripheral modules of the space station while Mission Control looked for accelerated pressure drops inside the sealed-off sections.
The tests will continue for at least 48 hours, during which time engineers will carefully watch the pressure building up in the well to make sure the damaged borehole can hold it in without a new leak popping open somewhere else.
