WinGD provides a range of manuals and tools to help its customers at all stages
of a project. From design engine to installation and maintenance, WinGD pro-
vides extensive help and support.
This manual is the initial guide to the installation process for this specific engine,
providing an overview of the different topics which need to be considered in the
project and the engine installation phase. In parallel to this manual are the
drawing sets and software tools which provide detailed values and ranges to help
finalise the installation process. Finally, each engine has its own range of opera-
tion and maintenance manuals to support the complete life cycle of the engine,
following the design and installation phase.
Marine Installation Manual Introduction
The Marine Installation Manual (MIM) contains all the necessary information
that must be considered in the engine design and installation phase. The MIM
provides an essential overview for project and design personnel. Each chapter
contains detailed information for design engineers and naval architects, enabling
them to optimise plant components and machinery space, and to carry out instal-
lation design work.
The MIM is not to be considered as a specification. The build specification is
subject to the laws of the legislative body of the country of registration and the
rules of the classification society selected by the owners. Also, guidelines for the
installation and operation from the makers’ side must be observed. Furthermore,
the engine requirements and any third-party maker requirements must be ful-
filled. System components are not the responsibility of WinGD.
The content of this document is subject to the understanding that WinGD has
prepared the data and information herein with care and to the best of knowledge.
However, the data and information contained in this document is subject to revi-
sion without notice. WinGD does not assume any liability with regard to unfore-
seen variations in accuracy thereof or for any consequences arising therefrom.
Reference to compliance All data are related to engines compliant with the regulations of:
•Revised MARPOL Annex VI
•NOx Technical code 2008
Reference information Specific values and design recommendations are included in the Marine Installa-
tion Drawing Set (MIDS), while the engine performance data is provided by the
General Technical Data (GTD). This chapter explains both tools.
