Pages count: 156
Description: ABS identified the need to provide a more detailed explanation of alignment design and practices, which
resulted in the development of the Guidance Notes on Propulsion Shafting Alignment. Their primary purpose is to provide clarification for ABS Surveyors and plan review engineers to verify consistency of the survey
and plan approval processes. Regarding the shaft alignment design and implementation efforts by the shipbuilding industry, these Guidance Notes are valuable to further advance its approach towards shaft alignment analyses and procedures. Additionally, ABS has developed state-of-the-art analytical tools primarily for the purpose of engineering analysis and design. The ABS shaft alignment program, combined with alignment optimization software, is capable of analyzing complex propulsion installations and, when used as a design tool, may provide an optimized solution to the alignment problem.
This 2019 edition is arranged to include additional topics on shaft alignment condition monitoring and a section dedicated to alignment problems and their solutions. Shaft alignment survey requirements are summarized in the introduction and are addressed further under a separate section on shaft alignment
procedures and practices. Discussion on alignment calculation and measurement is expanded to include the stern tube bearing clearance measurement. Additional clarification is provided on the application of the hull deflections, alignment optimization, propulsion systems with no forward stern tube bearing, and reverse
engineering calculation. These Guidance Notes become effective on the first day of the month of publication.
