Back on the Grid

Monday, August 25th, 2008

After a long three weeks on vacation, I’m back to blogging.  I had originally planned to put up a post or two while on holidays, but alas the WordPress interface over a dial-up connection required more patience than I possess.  Instead I spent my time with family and friends, camping and relaxing on the gorgeous beaches of eastern Prince Edward Island.  You can see why I was in no hurry to get back on the grid.  Speaking of grids, from the front steps of my childhood home you can see the wind turbines of the Eastern Kings Wind Farm. The wind farm consists of 10 Vestas V-90 turbines with a capacity of three megawatts each for a total capacity of 30 megawatts.  Every time I drove by them on my way to the beach, I couldn’t help but think of OPC and some of the projects connecting Vestas wind farms.

I got thinking even more about OPC when I read an article that the 10 turbines are now again all operational, after 6 of them had to be taken off-line for repairs to the gearboxes. The article said the faults where noticed during routine inspections.  Considering the gearboxes are 50 m in the air, in a windy location, I couldn’t help but wonder if they ever considered using on-line maintenance monitoring using OPC.  OPC Server connection to the turbine, OPC Data buffer and HDA transport tool to the maintenance application and you’re there. Maybe they could have caught the problem earlier?

Seems everywhere I go, I’m reminded of OPC.  Anyway, it’s time to shake the sand from my shoes and get back to business. There has been some interesting things happening with OPC over the last couple of weeks.  More to come on those topics soon.

Field of Dreams?

Friday, August 1st, 2008

No not the feel-good-cheesy Kevin Costner baseball flick, real fields.  Oil fields that is.  Whether the topic of conversation is soaring gas prices, environmental impacts or new technologies it all comes back to oil fields, and the fact that every year there are less barrels in the ground, and the stuff that is there is getting harder to reach. 

These and other factors, like cost higher prices for output,  a increasingly aging workforce, with decreasing fewer graduates entering the industry; increased competition; and more stringent health, safety and environmental (HSE) regulations together mean oil and gas companies need to seek greater cost-effectiveness.  One way to achieve this is improve traditionally labor-intensive oil operations into with technology-driven “digital oil fields.  The concept if far from pie-in-the-sky dreams.  As this article points out every major private-sector oil company has a digital oil field initiative in place — Shell’s Smart Fields, BP’s Field of the Future, and Chevron’s iFields as well as most large national oil companies, including Saudi Aramco, Petrobras, and Kuwait Oil Company.  Regardless of the name used they all share common characteristics with the Digital Oilfield of the Future (DOFF)

Any literature or presentation you see on DOFF will tell you that one of the keys to success is establishing a solid data architecture and communication infrastructure. Real-time data management is essential for capturing, storing, and distributing the data that provide real-time asset awareness and support fast, accurate decision making.  Good decisions mean good success, but only if they are made on timely access to high-quality data to lets the right people, make the right decisions at the right time.  Now where have I heard that phrase used before… Anyone? Anyone? Bueller? …the benefits of using standardized OPC communications and products.

What can OPC offer field of the future type initiatives? A few thoughts

- The breadth of OPC connectivity products makes it possible for companies to standardize all their connectivity, or better yet even from one OPC source.

- OPC is complimentary to a broad range of industry standard protocols yet independent of which ones each entity chooses to use. This eliminates the need for prolonged discussion around trying to get everyone to agree on the ONE protocol to use.

- OPC solutions are ideally suited to dealing with the growing legacy system problem

- Secure, DCOM-Free, and Firewall-compatible OPC technology allows for simple, hassle free data communications between upstream entities without colliding with the IT departments.

- OPC is well suited to work with real-time data, historical data and event driven data.

- OPC HDA solutions like Hub-and-Spoke architectures addresses data ownership issues by allowing different parties to store and share data without interfering with each other’s systems. This is especially important for remote operators who need access to up-to-date and recent history.

- OPC HDA history data links greatly simplifies consolidating historical data among different storage systems.

- OPC based redundancy and reliability solutions would be a given for remotely distributed assets like an oil field.

- And of course if you look you can find trusted OPC vendors who offer global, 24/7 support assistance J.

 

So what do you think?  Is the Field of the Future a Field of Dreams? or an achievable reality if everyone focuses on standards based solutions?  If you build it, they will come. (cost saving benefits that is)
