Machinery Room IntegrationMotivation
Already today and even more so in the future, further improvements in efficiency and emissions
can only be achievedby improving the whole system
or a sub-set of systems.

Machinery Room Integration / System IntegrationDefinition of System Integation
Clarification of requirements for the system and its components
Clarification of interfaces within the system and to its periphery
Ensuring compliance with the above requirements during development phase, e. g.:- Design and design studies using also analytical methods- Risk analyses
Installation into vessel including setting to work and trials
Documentation of integration work
Take the responsibility to fulfill the customer specification

Legislators and regulatory bodies set rules, standards and boundary conditions for industry.
E. g. emission legislation takes influence on machine room equipment.

Interfaces to Shipbuilders and OperatorsChallenges and Tasks for System Integrators
Challenges:- Maintain and extend the necessary know-how- Integration of additional / new components into limited spaces.- Ensure easy operability and maintainability of components and systems
Page 12 | Stefan Mueller | September 06th, 2012
Tasks of the industry:- Identification of optimum system functions in order to meet customer (with yards and
operator) requirements- Optimization of total system by intelligent combination of components (with yard)- Keep systems’ reliability- Ensure proper after sales support (with operator and yard) - Qualify operators for sustained system operation and maintenance
