Main Article Content
Abstract
An error in dimension and shape of the stern block can affect to a propulsion installation. It may result of less propulsion efficiency which can cause of unable in propelling at the maximum speed or unexpected fail of the system. There are 4 practical concepts that can be applied during the stern block erection; installing propulsion outfitting with care of hull deformation, referring propulsion ground marking during an erection of the stern block, preparing machining margin for propulsion outfitting and considering to apply a compensate disc for the propulsion system. In order to minimize a dimension and shape error in the stern block, both hull production team and propulsion installation team must fully understand those concepts and be able to apply them into their work processes.
