At the specific request of the ship owner, a regional shipyard engaged Goltens for the inspection and potential renewal of a 74,000 DWT Tanker’s damaged intermediate shaft journal. Goltens quickly responded and In-situ machining specialists immediately set off to inspect the damaged intermediate shaft journal.
After inspection, Goltens discussed the magnitude of the damage with the vessel’s superintendent and shipyard technical advisor and a repair plan and schedule was put in place.
Goltens mobilized its specialized tooling and equipment to the vessel and ran two continuous to complete the job due to compressed time requirements.
