Control Functions Clause Samples
The CONTROL FUNCTIONS clause defines the rights and responsibilities related to the management and oversight of specific operational or technical processes within an agreement. Typically, this clause outlines which party has authority to direct, monitor, or intervene in certain activities, such as system operations, data access, or compliance procedures. By clearly assigning control roles, the clause helps prevent disputes over decision-making authority and ensures that critical functions are managed efficiently and in accordance with the contract's objectives.
Control Functions. Local proprietary control systems will be utilized for many major pieces of Plant equipment not directly controlled by the DCS. These controls packages will be stand alone systems capable of safely and reliably controlling their equipment. These systems may be connected to the DCS via communications links and/or hardwired signals. The main functional areas to be controlled and monitored will be as follows: Gas Turbine/Generators. OTSGs/Duct Burners. Fuel Gas Compressors Steam Turbine/Generator Water Treatment System Electrical equipment including switchgear. Gas Metering equipment. Common hardware will be used throughout each system, based on multipurpose processing stations, which are software configurable and carry out signal conditioning, binary and analogue control, protection and data highway communications. Processing stations will be housed in equipment racks provided with duplicate power supplies and all associated equipment; this equipment will be housed either in the Electrical Room close to the PCR or local control compartments. Duplicate power supplies will be achieved through a supply from a secure distribution board associated with the emergency generator and a supply from a stable and reliable UPS system. The UPS/battery system will be capable of operating the local control system to enable safe shutdown of the Plant. Monitors in the PCR will be provided which will indicate key status points of both the CTG’s and the STG Control Systems, also starting and stopping functions shall be available from the DCS in the PCR. Each system shall communicate with its respective turbine local unit control systems via its own data highway. Major Plant systems to be controlled and/or monitored are: Combustion Turbine Generator Systems Steam Turbine Generator System CEMS Once Through Steam Generator Systems (OTSG) Feedwater Systems Demineralized Water Treatment System ACC and Auxiliary Cooling Water System Sample Panel Balance of Plant Systems Electrical Distribution System Monitoring Plant SCADA Fire Protection Systems
