DST has been supplying innovative control and monitoring systems to energy companies since 1980. Much of our experience can be segmented into...
DST has designed and implemented local and remote monitoring and control systems that included equipment status data collection (for maintenance), multi-protocol LANs to link disparate equipment, Life Safety, and remote (microwave) SCADA.
DST remains fully cognizant of the premiums energy companies place on reducing capital equipment costs and system reliability.
Projects include:
- Gas pipeline compressor station controls with HMI, data acquisition, archiving, report generation.
- Gas pipeline compressor unit control retrofit.
- Gas storage field SCADA/PLC system design and engineering for safety systems, injection and extraction wells, odorization and dehydration.
- Development and integration of Hand-held Computer (Palm OS device-based) data collection System for 1 billion cu.ft. LNG storage facility and multiple natural gas compressor stations. The system replaced clipboards, data sheet transcriptions, and keyboard maintenance data entry.
