Crash System. A continuous and independent data recording system is required for critical parameters. Data from this system is used in the case of an unexpected engine event that occurs when no SS or TR reading is being taken. The system shall have a minimum of 16 channels, each with a configurable scan rate (10 Hz to 5 kHz). It shall have recording capacity for a minimum of 72 hours of data. The oldest data is overwritten as the crash system runs continuously. Parameters to be recorded will be defined with the project progress. The system must be connected to an independent UPS and should include remote controls and feedbacks to the operators. An independent (or integrated with the PLC facility control system) display on the control console shall be installed to display main engine parameters in the event of a system crash. It must include also independent controls for engines such as Emergency Idle, Emergency Engine Stop, Motoring. It must include at least the following signals: - Ng (core speed) - Lube Oil Temperature, - Core vibration - Lube Oil Pressure - PLA - ITT Availability of above signals will be discussed during project progress. The system must be connected to an independent UPS. Computers for data acquisition system servers and programming shall be provided as needed, including a Windows-based utility workstation. All connections between various systems will be discussed during the project progress but network switches are required to link all systems and an external port to link with Customer’s network is required. UPS for all hardware supply is required, supplier to evaluate the minimum power required, in case of break out the UPS must be capable of maintaining power supply for a minimum of 30 minutes (see chapter 7.10.5, 7.10.6). A digital clock displaying the current GPS synchronized time should be available in control room.
