After experiencing fire last summer in one of its main motors, while deployed in Alaska, the U.S. Coast Guard cutter Healy, underwent one of the more unique overhauls. Over the course of two months, the vessel was drydocked and had the damaged motor replaced.
The U.S. Coast Guard published a time-lapse video showing the complex operation to repair the Healy and prepare the ship for a return to active service.
The fire disabled Healy’s starboard propulsion motor and shaft, forcing the ship to stop its deployment on a combined science and national security mission in the Arctic.
While the cutter was awaiting the arrival of the motor, it was placed in dry dock where its hull was cleaned and inspected.
Then, the process started to dismantle the damaged motor. To remove the motor from the ship and put the new on aboard required cutting out a big section of the hull which was moved by a special heavy lift crane and placed behind the ship.
After that, a winch and a and pulley system were used to hoist sections of the old motor out the side of the ship. The process was reversed to position the new motor into the engine room in mid-November before they connect the replacement motor and repairing the hull.
The biggest portion of the live-saving operation has now been completed, and the Healy is preparing to return to deployment.
