This Project Guide is intended to provide the information necessary for the layout of a marine
propulsion plant.
The information is to be considered as preliminary. It is intended for the project stage only and
subject to modication in the interest of technical progress. The Project Guide provides the gen-
eral technical data available at the date of issue.
It should be noted that all gures, values, measurements or information about performance
stated in this project guide are for guidance only and should not be used for detailed design
purposes or as a substitute for specic drawings and instructions prepared for such purposes.
Data updates
Data not nally calculated at the time of issue is marked ‘Available on request’. Such data may
be made available at a later date, however, for a specic project the data can be requested.
Pages and table entries marked ‘Not applicable’ represent an option, function or selection which
is not valid.
The latest, most current version of the individual Project Guide sections are available on the In-
ternet at: www.mandiesel.com under ‘Marine’ ‘Low Speed’.
Extent of Delivery
The nal and binding design and outlines are to be supplied by our licensee, the engine maker,
see Chapter 20 of this Project Guide.
In order to facilitate negotiations between the yard, the engine maker and the customer, a set of
‘Extent of Delivery’ forms is available in which the basic and the optional executions are specied.
Electronic versions
This Project Guide book and the ‘Extent of Delivery’ forms are available on a DVD and can also
be found on the Internet at: www.mandiesel.com under ‘Marine’ ‘Low Speed’, where they can
be downloaded.
