Replacing a broken propeller
On May 2009, a 70m LOA spanish fishing vessel recalled Montevideo Port, in search of drydock to replace a broken propeller.
As all drydocks in the area were full, the owner trusted our company to accomplish the job.
A five divers team, working with reduced water visibility, replaced the broken propeller (one blade missing) in some days.
After trying with no success to release the propeller from the tail shaft , using a 120 tons hydraulic jack, it was finally decided to cut the propeller boss.
Once this step was accomplished, the broken propeller was removed and the new one set in place.
One hour after completion, the vessel got underway to her assigned fishing zone (South Atlantic), at entire owners satisfaction.
