Data Acquisition Systems (DAS)
Our Snubco Data Acquisition System consists of one basket-mounted touch screen for data input and setup and the Snubco base station.Base Station: Located at ground level and normally mounted in a doghouse or data cab, our base station incorporates four CPU panels/receivers that house the control system software. The system communicates through a Class 1 Division 2 router to all of the wireless sensors (transducers, proximity sensors and pressure sensors). The wireless devices are used to monitor the operation of the hydraulic workover unit, snubbing unit or rig. The basket-mounted touch screen station is a slave station that replicates the base station display. This is a wireless connection to the control center that operates on a web server for ease of access The wireless network allows for communication from a remote laptop or any wirelessly enabled device. Access can be granted to other personnel from any laptop and permissions can be set for different user access.
Snubco DAS Components:
Snubco SnubSmart (DAS) base station is the central point of the management system. This base station is located outside the hazardous zone and once initial setup is complete, the system can be locked out so that no tampering can take place. The base station’s unique feature is that other than power and a few magnetic mount antennas, the system is wireless. The station can also be customized to fit into a package not much bigger than standard luggage or can be customized into a single offshore skid that contains all the data management and control systems for easy transport. Power supply to the system can be customer specific, but 24 volt is the default specification.
Operators Panel (Slave Station)
The operator’s control station or slave terminal is mounted in the work basket. This station allows the operator to view all relevant information that is being captured by the system. The entire enclosure is Class 1 Division 2. This station retains some functions that can be controlled by the operator such as:
- Changing the display units (psi, torr, barr, etc.)
- Ability to zero snub and lift force for calibration
- Ability to zero string weight for weight on bit
- Remote view of battery lift of each transducer
- Remote view of signal status of each component
- System alarms
- Calibration screens
- Management of change permissions
- Tank levels and fluid pumping
