When Wartsila has a small problem, it is a huge problem for any other company.
Wartsila makes some of the largest propellers in the world, for the largest ships in the world, for the largest
Navy in the world.
CBG’s President was able to arrive on site in five minutes, an advantage of CBG’s new location in Portsmouth, VA.
The tap was a 4-inch tap, broken off
5-¾ inch deep in the hole and the prop was due to be picked up in a few days for transport to a ship.
A plan was made to disintegrate the tap starting the next day.
CBG set up one of their Cammann Inc. portable Metal Disintegrating Machines and using a square electrode, disintegrated the flutes off the broken tap, facilitating the removal of the tap. With no damage to the threads, a new tap was used to complete the threading process and the propeller was ready for shipment ahead of schedule.
