Data Logging
Subsea Data Loggers
Our compact, self-contained, subsea data loggers are highly accurate, reliable and easy to configure. Readings can be viewed locally on the OLED display or transmitted remotely over several optional interfaces.
Our data loggers are also able to provide a visual indication of whether a test has passed set acceptance criteria prior to recovering the unit and the analysing data upon request. This functionality will vary depending on pressure testing design code and client requirements.
Typical data that can be recorded as standard include: date, time, pressure, flow rate, total volume added/released and subsea temperature. Additional parameters can be logged upon request.
Features
Data Recording
Our pressure testing dataloggers are compact and simple to deploy, install and operate.
An onboard OLED screen provides a visual readout of instantaneous data in addition to an internal SD card that stores all recorded data for later analysis.
Typical data can be recorded or it can be bespoke to client request.
Greater Flexibility
Our dataloggers can be isolated and disconnected from the system, leaving them to locally monitor and store information whilst a system remains on test.
This allows for ROVs, divers or the entire vessel to perform excursions away from the worksite, either to support testing activities by performing visual inspection, or to carry out other construction/project related activities in parallel to pressure testing.
Test Acceptance
Our dataloggers can be adapted to provide visual confirmation of a successful test in-situ, without requiring the unit to be recovered to deck and the data analysed.
Divers and ROVs can quickly tell if there has been a successful test, whereby the pipeline system can be depressurised and dataloggers recovered for data analysis, or if a test has not been completed and shall remain on-test for longer.
Data Logging Manifolds
With relevant onboard isolations, our datalogging manifolds are able to connect to and monitor up to four systems at once as standard.
Simply connect our unit subsea between the systems to be tested and downline (connected to a conventional vessel based pressure testing spread) and pressurise through our datalogging unit.
Once each system reaches their required test pressure, the unit can be isolated and disconnected, freeing up the vessel to perform other activities.
Our units will continue to monitor and record data during the test and can depressurise each system subsea once a test has been completed successfully. This can be done via diver/ROV or autonomously if required.
Features
Data Recording for Multiple Systems
Our datalogging manifolds enable the ability to monitor and record data for up to 4-off separate systems at once. Each system has a dedicated data logger in order to monitor each test individually.
Our datalogging manifolds have been designed to be compatible for both diver and driverless operations, are simple to install and operate.
Multiple System Testing
Our datalogging manifolds have individual dataloggers dedicated to each system on test.
When monitoring subsea pressure tests, our dataloggers can be adapted provide visual confirmation of a successful test in-situ, without requiring the manifold to be recovered to deck and the data analysed.
Controlled Depressurisation
Once a pressure test has met predefined acceptance criteria, the system is then depressurised to ambient prior to any required intervention.
This can be done manually via diver or ROV operable valves incorporated into the datalogging unit or autonomously once the system has passed its pressure test.
