Introduction
Our project guides provide customers and consultants with information and data when planning new plants
incorporating four-stroke engines from the current MAN Diesel & Turbo engine programme. On account of the
modifications associated with upgrading of our project guides, the contents of the specific edition hereof will
remain valid for a limited time only.
Every care is taken to ensure that all information in this project guide is present and correct.
For actual projects you will receive the latest project guide editions in each case together with our quotation
specification or together with the documents for order processing.
All figures, values, measurements and/or other information about performance stated in the project guides are
for guidance only and shall not be used for detailed design purposes or as a substitute for specific drawings
and instructions prepared for such purposes. MAN Diesel & Turbo makes no representations or warranties
either express or implied, as to the accuracy, completeness, quality or fitness for any particular purpose of the
information contained in the project guides.
MAN Diesel & Turbo will issue an Installation Manual with all project related drawings and installation instructions when the contract documentation has been completed.
The Installation Manual will comprise all necessary drawings, piping diagrams, cable plans and specifications of
our supply.

Where dublicated measurements are carried out, i.e. multiple similar devices are measuring the same parameter,
the ID specification is followed by a letter (A, B, ...etc.), in order to be able to separate the signals from each other.
