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.
Increasingly ROVs are being utilised to conduct Subsea pressure and leak tests as they can usually be performed off rig time and remove the need for running an umbilical.
+ 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.
