ROV Pressure Testing with the DARTT Recorder
The DARTT Recorder’s innovative design and equipment enables its use on any ROV pressure test. The new Subsea Pressure and Temperature sensor is rated to 4000m of seawater without the use of a 1-atmosphere housing, making the system leave an extremely small footprint with less hydraulic and electrical connections.
The new Subsea Pressure and Temperature sensor is rated to 4000m of seawater without the use of a 1-atmosphere housing.
The system has a small footprint with minimal hydraulic and electrical connections for ease of installation, low maintenance and high reliability.
ROV pressure testing can now be performed with all of the advantages of a surface DARTT Recorder.
DARTT Recorder Pressure Testing and Leak Detection
An example of an ROV DARTT Recorder pressure test is running a Subsea Tree with a crane or deployed on drill piping without an umbilical. The pressure test of the Subsea Tree x Wellhead is critical and almost always a Well Acceptance Criteria test (WAC). Using the ROV DARTT Recorder provides the following unique advantages:
Thanks to the sophisticated nature of the tooling, you will see almost immediately if the Subsea Tree x Wellhead connection pressure test is going to pass. This provides a decision point for recovering the deployment equipment and the decision point is reached faster and with more certainty than any other way using an ROV DARTT Recorder.
The Subsea Tree x Wellhead connection pressure test result will be achieved with an unquestionable result. The pressure test cannot pass unless it has met the pressure test specification entered adding certainty to the WAC.
As with all DARTT Recorder pressure tests, this critical pressure test will be automatically documented and saved with all required traceability information, including an equipment calibration certification.
Equip yourself with right ROV tooling when pressure testing
There are many more advantages in using an ROV DARTT Recorder on your projects. Ideally, surface pressure testing is performed with DARTT Recorders to keep ROV and Surface executed pressure testing workflows systematic.
+ How will an ROV DARTT Recorder save time?
Thanks to the high accuracy, ultra-precision digital pressure gauges and negative pressure testing functionality, The ROV DARTT Recorder identifies a passed test instantly. The tendency for an operator to extend the hold period of a paper chart “just to be sure” is eliminated. Our case studies show this alone can save tens of thousands of dollars on a BOP testing sequence.
The predictive features of the DARTT Recorder helps an operator decide early weather to bump pressure, start trouble shooting for a leak, or standby as the test will pass as is. These features change decision making from subjective to matter of fact, and save a lot of time per test.
There are many other features that save time, contact us for more details.
+ Eliminate False Passes
Eliminate the risk of incorrectly assessed tests. The ROV DARTT Recorder only passes a test that has met the companies specification.
Consequences of false passes can be catastrophic….who needs that risk.
