Project scope
- HAZOPs assessments
- DCS coding and design
- Development of functional specifications
- DCS/SIS software implementation
- Designing the network and hardware architecture
- Development of factory acceptance testing procedures
- Development of hardware/software migration for dynamic shutdown planning
Project highlights
