Page: 41 of 81 Project name: Project number: Quotation number: Created by: Document Id: Document creation date: Power Supply Upgrade. LGL P0900329 Q0900869 MNO002 August 25, 2009 The Power Barge is controlled and supervised from the Wärtsilä Operator Interface System (WOIS workstation). All actions necessary for the normal operation, such as start and stop of the generating sets, load increase and load reduction are activated and supervised via the WOIS workstation, using a mouse, keyboard and display. The operator can also supervise key data from the plant such as various temperatures and pressures as well as measurements of electrical variables such as generator power, voltage and frequency. The WOIS workstation also includes a hardcopy laser printer. WOIS workstation includes the following functionality: • Process status displays, where the status and operation of the processes are displayed using various dynamic objects, such as images of pumps, valves and other components and units. The status of these objects is displayed graphically. By interacting with an object, the function and operational status can be displayed. • Process trends can be displayed as a free combination of six (6) measured values such as pressures, temperatures, speed, generating set load, etc. The operator may combine the values of interest in one graph to get a good view of the total process for further analysing. The trends are stored for up to 180 days, and the operator may call back a trend for any time interval within these limits. • An alarm banner in the uppermost part of the displays informs about the latest occurred alarm. The active alarm list informs the operator of possible problems in the process. An alarm will remain on the active alarm list until the process has returned to normal state and the alarm has been acknowledged. Historical alarm and event lists can be called up for further evaluation of events. • Any of the displays and the alarm list can be printed to the hard copy printer.
