Shaft Alignment

Course information

Target group:

Who the course is for: The course Shaft Alignment is aimed at anyone interested in understanding the importance of shaft alignment and the various methods utilized for the alignment of shaft lines. This may include: Ship Managers, Technical Superintendents, Ship Masters, Officers and Seafarers; Shipyards Technical Staff; Surveyors; P&I and/or Insurance Inspectors; Naval Architects; Marine Engineers; Etc.

Description:

Presentation

This training course describes the various components of a shaft line and the different types of shafts and their couplings, the importance of shaft alignment and the various methods utilized for shaft alignment. The course provides also a brief introduction to the vibrations that may affect the shaft lines.

Objectives

On completion of the training, students will be able to:

Get familiar and understand the components of a shaft line, know the types of shafts and their couplings, understand the protection required and the shaft line components scantlings and get familiar with the required tests and certification of shaft lines.

Understand the importance of shaft alignment and the factors influencing the alignment, know the different alignment methods currently employed and understand the shaft alignment issues for installations other than the main shafting line.

Understand the different types of vibrations that may affect shaft systems, know the general principles of torsional and axial vibrations and get familiar with the vibration control methods and vibration tests and measurements
