    Intelligent Pressure Testing and Rate of Change

    Pressure testing specifications imposed by verification body standards include the following parameters:

    • Test Pressure
    • Hold Period
    • Allowable Pressure loss (over the hold Period)

    Thorough pressure testing specifications will also include:

    • Min Test Pressure
    • Max Test Pressure
    • Improving Trend [True/False]

    To aid in testing, Test Pressure and Hold Period can be combined into a rate of change (ROC). For example, where the Hold Period = 10min and the Allowable Pressure Loss = 30psi, the Average Allowable ROC = 3psi/min. That is, if the average rate of pressure change during the 10min Hold Period =< 3psi/min, then the hold and allowable loss component of the test specification will have been achieved.

    Once we know the Average Allowable ROC, we apply it to a test by sampling a short duration of pressure x time data and multiply it out to display it as psi/min, then compare that to the specified Average Allowable ROC.

    Pressure Test Result Prediction with Average Allowable Rate of change

    The DARTT Recorder samples data over a few seconds, removing motion induced pressure noise (vessel or rig heave causing water hammer) and displaying psi/min.

    So why is using the ROC of such significance?

    1) You cannot pass a pressure test until you have met the Average Allowable ROC

    2) Typically, the ROC will be met well before the end of a pressure test Hold Period.

    Note: The image below shows the pressure line turn from blue to green as the pressure tests ROC meets or exceeds the Average Allowable ROC for the pressure test specification. You can see approximately 1.5 min in to the 5 min hold period, the DARTT Recorder is showing an inevitable pass.

    Save Time Pressure Testing with a DARTT Recorder

    The ROC User Interface, combined with the DARTT Recorders other test health functions, such as “Trend” and “Prediction”, can save a lot of time when pressure testing. They also make trouble-shooting leaks significantly faster and more definitive.

    ROC displayed during a test can tell the operator not to “bump” pressure when the ROC has been met and the predicted end test pressure will not be below the minimum test pressure.

    Alternatively, if you have not met the ROC, and the test is not showing an “Improving Trend”, then the test is not going to pass as things stand. Most likely caused by a leak somewhere in the system that needs rectifying, so prolonging the hold period is wasting time.

    Test with confidence

    ROC, Trend and Prediction functions give an unprecedented level of confidence in the results during the test. Having a pressure-testing tool that can provide an objective pass/fail based on the given criteria removes the second-guessing and allows the focus to be on the next step, not whether the last step was correct.

    Further Application of the DARTT Recorder ROC Pressure Test Assessment

    Consider running Riser for a BOP or Intervention System. It is desirable to confirm each Riser connection before running the next. Usually once the BOP/Intervention system has been landed and latched, a final pressure test re-tests all previously tested connections.

    Save a lot of time without reducing quality by pressure testing these and similar connections until the Average Allowable ROC has been met. Very little (if arguably any) assurance is gained by holding such a pressure test beyond this goal.

    Just because summer is winding down, it doesn’t mean that road travel is. For many drivers, the end of summer temperatures are a reminder of change to come. Some drivers are soaking up the last few weeks to hit the trails and the sand, or take a local day trip. Others are packing up and taking those college kids to campus.  Any way you slice it, change is coming and change of season, means change for your vehicle’s tire pressure.

    Every year we’re all reminded to check the batteries in our fire alarms when we change the clocks. So why not use the change of season as a reminder to check your tire pressure? You can always bring your vehicle to a qualified mechanic to check your tire pressure. But, with a simple air pressure gauge and a 12 volt portable air compressor you can check your tire pressure and adjust your tire pressure at your convenience.

    Tire pressure is affected by temperature so it’s very important that you do check the pressure when the seasons change and the temperature fluctuates. Don’t forget air is a gas that expands when heated and contracts when cooled. In most parts of our country, this makes fall and early winter months the most important times to check your tire pressure. As summer comes to a close, there are a few things we can count on.  The seasons will change, the air will get crisper and your tire’s air pressure is going to go down. More Read On

    To check your tire pressure you first need a tire air pressure gauge.  There are different types of air pressure gauges. There are digital, stick or dial gauges.  Grab yourself a gauge and check your pressure. Now, if you have the original tires that your car came with, you can easily look inside the driver’s side door to see what the recommended PSI (pounds per square inch) is for your tires. It’s most likely in your owner’s manual as well. Remember that that number is the maximum amount of air your tire can hold, not the recommended pressure. If you have aftermarket tires then you are going to want to go to the tire manufacturer’s website or contact customer service to confirm this information with them before you go any further.

    Once you have your recommended tire pressure, you’ll need a 12-volt portable tire inflator that suits your needs. There are different air compressors that are meant for different sized tires. For instance, the MF1035 is a good fit for a passenger car size tire while the MF1050 would be better for a small light duty pickup truck or SUV. If you’re lucky enough to be driving around with cool, larger tires you might want to check out the MF1089 because that packs quite a punch and it’ll top off bigger tires fast.

    You may say, “Humph, who cares… As long as I don’t have a flat, does the air pressure in my tire REALLY matter?” Yes, yes it does. It’s a no brainer. Keeping your tires properly inflated is safer, helps prevent unnecessary wear and tear on your tires so they last longer, and even helps save you money on gas. So, when the seasons change use it as a reminder to check your tire pressure, or you can count on writing a check for some new tires quicker than you think.

    Google tools for business productivity and growth

    Although our core business may be teaching students how to drive, we are in fact “marketeers” as well!  Without marketing, we can be the best Driving Instructor in the “hood” but our business may be slow to grow.  Attracting new students and parents to book more driving lessons is essential in order to survive!  Competition is rife.  In essence, it starts with an excellent customer experience for our students and parents as well as providing them with value-add information.

    How do we find time to be more productive and free up some of our time to put into marketing?  Some of us may have back office support behind us to attract new business on our behalf, but if you are a solo driving instructor in Brisbane or small driving school in Brisbane it really is down to us.  Start seeing yourself as  “small business entrepreneurs”.  It will amaze you how this changes one’s mindset and opens up new opportunities to a new way of doing things!

    There are a bunch of different ways to boost your business.  Sometimes it can be overwhelming with different tools and apps out there. Let’s start with Google and what it has to offer.  Naturally, we all want to see our website ranked on page 1, but Google is not simply a search engine.  The good news is “Google” provides us as individuals and as business owners with a number of great FREE tools to use.

    Check them out – you may not find all of them useful, but certainly one or two of them will come in handy:

    Gmail

    How do you stay in touch with your customers?  You may or may not currently use Gmail, but is a great email provider for businesses simply due to all the built-in functionality that you get with using it. Gmail is definitely worth considering if you currently use a different email provider.

    If Gmail is your thing – a Gmail inbox can become overwhelming and be distracting with spam emails, alerts and information overload.  To keep your email organised, you need to look at it as a marketing tool as opposed to a basic account.

    Google Photos

    The FREE Google Photos app can be downloaded from ITunes and Google Play to store and organise your photos on mobile devices. Google Photos acts as a backup for unlimited photos and videos and these can be accessed from any device.  See more on how Google Photos work with Google Drive.

    To access Google Photos from your desktop, simply log into your Gmail account, then open photos.google.com and access the Photos icon form the drop down on the top right-hand side.

    Google Photos allows you to edit your photos and share them on Facebook or with selected people.  You can also make movies, animations and collages which can easily be used on your social media channels.  This is a great FREE tool to use for marketing.

    Google My Business

    As a local Driving Instructor or small local Driving School, Google My Business is something you shouldn’t overlook as it is geared towards helping potential customers find you locally.  Essentially it is a free listing but also allows you to add a lot of business information allowing people in your local area to learn about your business and the services that you offer.  Additionally, it is a great place to build a stronger brand and reputation by building your reviews as an instructor or school.  It’s important to fill in as much detailed business (https://www.business.gov.au/) information as possible.  Once verified, make sure your Google My Business Listing is complete and up-to-date or you could lose potential customers. Your listing can help convince potential students and parents to book lessons with you as a listing generates trust that you are a reputable business.

    In our opinion, Google My Business is by far the most important Google+ feature, especially if your business has a local presence. Your listing will increase your visibility in local and mobile search and allows customers to check out your verified business website.

    Google Trends

    Writing blogs for your Driving School can be time-consuming but your students and parents will appreciate value-add information and a great way to generate fresh ideas for blog and social media posts is by using Google Trends to get creative.  Explore trending “stories” or select topics of your choice and those that may be of interest to your students and parents.  See what’s trending in the learner driver space.

    Google+

    Google+ is a powerful tool allowing you to connect and share content of interest.  It is good to have a presence on Google+ as a Driving Instructor or school as this can help grow your contacts and discover new and interesting content.  Take time to post regular posts to your Google+ page (you can use the same content as your Facebook posts) – it is good to be active in this space!

    This is just a smidgen of the tools that Google offers – from staying connected, staying organised, working smarter through to growing your business – Google has something for everyone!

    A good place to start to increase your productivity as a Driving Instructor or Driving School is to automate the mundane tasks in your business, providing your students and parents with an excellent modern customer experience. Secondly, look at activating your FREE profile page with YLOO Drive and increase your ranking in your local area over time.  Profile pages are SEO-friendly and designed with Google in mind, to help grow your business and attract more bookings.
