The scope of Works for LOT 6 includes the design, engineering, programming, supply, erection, testing, commissioning and documentation of the Contract Object, an Overall, main, DCS system for ASV6 incl. overall project management for Lot 6.
For a more detailed description of the scope of works for LOT 6, see section VI.3) Additional Information.
DONG Energy Bioenergy & Thermal Power A/S (Employer) intends to establish a new biomass-fired CHP-unit at Asnæsværket (ASV). The new unit is called ASV unit 6 (ASV6). ASV6 is an industrial sized unit that produces process steam, district heating and power by combustion of woodchip based biomass fuels. The unit will be connected to existing infrastructure for process steam and district heating. The power plant site is placed directly in connection with the costal line. Fuel supplies are provided via ship, more specific via barges, or via truck as alternative.
ASV6 Bio includes establishment of a completely new ‘brown field’ biomass fired power plant, comprising a fuel logistic plant, a boiler plant (including steel structures for building, facades, flue gas cleaning, flue gas condensing, etc.), and a turbine plant for the production of district heating and process steam for industrial purposes.
The scope of Works for LOT 6 includes the design, engineering, programming, supply, erection, testing, commissioning and documentation of the Contract Object, an Overall, main, DCS system for ASV6 incl. overall project management for Lot 6.
The processes of ASV6 are divided into a number of LOT specific processes, each controlled by its own Control Subsystem/Process Station, which includes control behaviors in field level (local level) and which is designed to be operated from a DCS system's/Process control system's supervisory control level/HMI, but which can also operate autonomously, independently of the operating system. The main DCS shall unify the different individual Control Subsystems/Process Stations (which are distributed throughout the overall main — DCS system), into one supervisory and control level/HMI to establish a completely homogenous operator environment based on the overall main — DCS system.
The main DCS of ASV6 shall be designed as an independent distributed control system, and shall work independently of the current DCS of ASV unit 1-5. The system will be installed in a standalone process building separated from the rest of the power plant's production units. It is, however, foreseen that selected parts of the current processes of ASV1-5 are to be operated via the DCS of ASV6 (such as start/stop — commands, and monitoring of in/out, and Error — states, of entire function units of ASV1-5).
