Broken Crankshaft Balance Weight Bolt on Ships Main Engine
Foretract deploy to Denmark to carry out urgent stud removal from supply vessel main engine crankshaft. A same day response was required when a supply vessel superintendant called with a requirement to remove a broken crankshaft balance weight bolt. A method was developed using information provided by the Danish engineer, special tooling was manufactured immediately and a technician travelled by overnight ferry to Denmark.
On arrival at the vessel the next day, Foretract’s equipment was set up and the stud successfully removed by operating Foretract’s spark erosion equipment inside the engine crankcase via the crankcase door. The entire inside of the crankcase was sealed off using plastic sheet to prevent contamination of the lube oil.
The Foretract technician returned to the UK on the same ferry, leaving Denmark just 5 hours after arrival in the country
