RESULTS OF A SURVEY ON SHAFT ALIGNMENT PROCEDURES USED BY AMERICAN SHIPYARDS

Despite its importance, the subject of shafting alignment is not always adequately addressed during construction and repair of ships. Therefore, in an effort to determine just how well shafting alignment is understood and handled in American shipyards an alignment survey of American shipyards was conducted. The results of the survey are presented in this report. In addition to the survey results, the report addresses some of the basic criteria used to evaluate the acceptability of a shafting system from an alignment standpoint and suggests certain features found in some shafting systems which make them very prone to alignment problems. Methods of establishing and checking alignment are also discussed. The report should offer both owners and shipyards some guidance concerning what types of alignment checks can and should be expected when a problem exists.
