Resumo: The strain gage method for propulsion shaft bending moment verificationhas been in use since the 80’s. In this work, the authors present theirprocedure and results of this method to an Anchor Handling Tug Supply(AHTS) ship. The method was applied in this ship in two occasions: afterdelivery in 2018 and after a grounding accident in 2019. After a period ofhull repair, the bearing reactions were verified at the same time by Jackupand Strain Gage methods. The results by the Strain Gage techniqueare considered more accurate and complete than those of the Jack-up.Based on the Strain Gage results, it was concluded that the groundingaccident caused a change in the alignment of the shaft lines, mainly onstarboard side. The comparison between the methods presented thesame graphic shape, however the Jack-up measurements differed fromthe Strain Gage ones at some points due to some factors noted anddiscussed by the authors.

Neste trabalho, osautores apresentam o procedimento e os resultados deste método paraum navio Anchor Handling Tug Supply (AHTS). O método foi aplicadoneste navio em duas ocasiões: após a entrega em 2018 e após umacidente de encalhe em 2019. Depois de um período de reparo do casco,as reações dos rolamentos foram verificadas ao mesmo tempo pelosmétodos Jack-up e Strain Gage. Os resultados pela técnica Strain Gagesão considerados mais precisos e completos que os do Jack-up para estecaso. Com base nos resultados do Strain Gage, concluiu-se que o acidentede encalhe provocou uma alteração no alinhamento das linhas de eixo,principalmente a boreste. A comparação entre os métodos apresentou amesma forma gráfica, porém as medidas do Jack-up diferiram das doStrain Gage em alguns pontos devido a alguns fatores apontados ediscutidos pelos autores.Escola Politécnica de Pernambuco2023-09-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttp://revistas.poli.br/index.php/repa/article/view/248710.25286/repa.v8i3.2487Journal of Engineering and Applied Research; Vol 8 No 3 (2023): Revista de Engenharia e Pesquisa Aplicada; 1-11Revista de Engenharia e Pesquisa Aplicada; v. 8 n. 3 (2023): Revista de Engenharia e Pesquisa Aplicada; 1-112525-425110.25286/repa.v8i3reponame:Revista de Engenharia e Pesquisa Aplicadainstname:Universidade Federal de Pernambuco (UFPE)instacron:UFPEporhttp://revistas.poli.br/index.php/repa/article/view/2487/885http://revistas.poli.br/index.php/repa/article/view/2487/886Copyright (c) 2023 Marcelo dos Reis Fariashttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessFarias, Marcelo dos ReisBaptista, Luiz A.
