M/V Annetta / tail shaft manufacturing
Last week we sent this new tail shaft to its owner - the vessel M/V Annetta.
It´s a tail shaft for a water-lubricated system. The old propeller shaft had suffered from severe cavitation between the liners making it unrepairable.
The shaft dimensions are Ø352 x 5665 mm with 2 bronze liners Ø405/352 x 1697 mm and Ø378/338 x 1010 mm and with Phillyclad coating between the liners.
The manufacturing time was only 10 days including coating. We used C45 steel for the shaft - bronze material for the liners and Phillyclad as a protective coating to avoid future corrosion between the liners. This solution is a cost-effective solution.
