With relevant onboard isolations, our datalogging manifolds are able to connect to and monitor up to four systems at once as standard. Our smart datalogging technologies can display when pressure tests have been successful and can depressurise the system in a steady and controlled manner.
DATA RECORDING FOR MULTIPLE SYSTEMS
DATALOGGING CAPABILITIES WITH A SIMPLE INTERFACE
Kraken Subsea's 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.
OLED screens provides a visual readout of instantaneous data in addition to an internal SD card that stores all recorded data for later analysis.
Typical data that can be recorded as standard include: date, time, pressure, temperature, flowrate and total volume added / removed. Additional parameters can be logged upon request.
MULTIPLE SYSTEM TESTING
PROVIDING TEST CONFIDENCE FOR MULTIPLE SYSTEMS
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.
This way, once a vessel has returned to the worksite after the test minimum hold period, divers and ROVs can quickly tell if there have been successful tests, whereby the appropriate pipeline systems can be depressurised and dataloggers recovered for data analysis.
If any tests have not reached a successful test, these can remain on-test for longer or re-presurised if tests have failed.
MANUAL OR AUTONOMOUS 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.
Depending on requirements, our units can have pre-designed orifice plates to control depressurisation rate or variable flow valves that are controlled via the depressurisation rate instantaneously.
If using our autonomous models, this means that once a system has been pressurised, vessels are free to leave the worksite and return to a completely tested and depressurised system and the unit will only require disconnection and recovery.
