E N D
Introduction • Introduction of the Trainer • Mr. Matthias Schmidt I&C scope • Scope of maintenance course • The scope of the maintenance course is to make you familiar with the maintenance and the maintenance documents of the different systems of SIEMENS scope of supply including on site inspections and examples. • The indicated maintenance steps are an extract out of the O&M Manual. They do not describe the overall maintenance of systems en detail and are therefore not binding. This presentation shall be understood as a guideline. • The operation department is responsible for taking plant readings to identify any equipment requiring additional maintenance (e.g. due to high temperature, high vibrations, varying measurements).

Introduction to maintenance • As with any machine gas turbine plants are subject to wear during use. Maintenance is performed to detect and control wear, as well as to repair or replace wear parts as needed to restore wear reserves. With proper maintenance, gas turbine plants can be operated with high reliability and availability. • The manufacturer's maintenance instructions are based on experience gathered with the fleet of gas turbines in service and are updated continually. SIEMENS gas turbine plants are characterized by a straight-forward, maintenance-friendly and robust design, which permits long inspection intervals and minimizes the maintenance effort required. • Maintenance and monitoring are required both during operation and when the unit is at standstill. • Some maintenance work should preferably be performed with the unit at rest, e.g. in the case of any special conditions being noted in the operation log, while other maintenance work may be carried out during normal operation. • “Day-to-day maintenance” or “running maintenance” encompasses all activities which can be performed on the gas turbine and its auxiliary systems without adversely affecting the availability of equipment that is running or on standby. Maintenance includes measures to maintain the specified condition of the plant.
Introduction to maintenance documentation • Operating Manual (Overall Plant) • The Operating Manual contains necessary information for the staff operating the power plant as overall plant. • Operating & Maintenance Documentation (Documents & Data representing Final Layout and Product Handling) • The Operating & Maintenance Documentation comprises technical documents and data required for the description of the set-up and functioning of power plant components and systems, and for their operation and maintenance. • Erection & Commissioning Manuals • Compilation of requirements for the civil engineering, initial erection and initial commissioning of power plants or power plant components. The manuals are prepared for the customer according to PG's scope of supply and services, where appropriate, including the documents from contractors. • Site Documentation • The site documentation comprises the proofs, protocols, certificates etc. arising during initial erection and initial commissioning in the form of quality records (QC). The structuring characteristics are the same as those for the operating & maintenance manuals.
