As the recently taken photo indicates, MarineShaft had quite a busy summer. As always, our team was ready to step in extra hours, to solve some urgent repairs. Today I would like to share a couple of these repair cases with you.
MT Arctic Flounder – alignment of propeller equipment – Kamewa CPP System
When MarineShaft was contacted, the 228,5 m long tanker MT Arctic Flounder was in dry-docking for repair. The tail shaft OD-Box shaft & intermediate shaft had been removed from the vessel and transported to a shipyard's workshop, where the run-out measurement showed app. 0,5 mm bentness/misalignment.
MarineShaft, when necessary, send a service engineer to location to carry out the alignment tests for our customers. In this case the run-out measurements were handled in co-operation with the vessel owner and shipyard, and on hand of drawings MarineShaft could give a repair solution/quotation.
MarineShaft received tail shaft CPP Ø1500/565 x 7549mm including hydraulic pipe, OD-Box shaft Ø950/500 x 2535 mm and the intermediate shaft Ø500 x 6775 mm in our workshop in Hirtshals, Denmark Mid-July.
As the flange showed deflection, we machined the reamer holes in flange, increasing them by 1 mm. We manufactured new hydraulic bolts and sleeves to fit.
