rov pressure testing

We made the DARTT Recorder pressure testing units compatible for ROV pressure testing operations after client feedback and feature requests. The sensor is mounted on the ROV and the surface readout unit (DARTT Recorder Embedded Software Touchscreen) is operated from the control cabin. We greatly appreciate the client feedback and feature requests as this is how we build the perfect tools and this ROV version has become quite popular. The ROV DARTT Recorder is even easier to install now as it no longer requires the 1 atm housing.

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 Calculator change during the 10min Hold Period =

The pressure / temperature sensor has been re-designed with the following;

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.
