Alatas Turkey’s technicians came to the ship to repair the deck crane’s hydraulic hoisting motor failure. When they examined the crane, they discovered that the hosting hydraulic motor was the source of the issue. The lifting hydraulic motor was moved to the ship’s workshop. They established removal, disassembly, replacement, and detection procedures to address the issues.
The technicians from Alatas Turkey came to the ship to repair the deck crane’s hydraulic hoisting motor failure.
The Alatas Turkey technicians arrived in Morocco, attended to the vessel, held a meeting, and then began the maintenance work.
- Alatas Turkey’s technicians visited Nodor, Morocco. A meeting was called to discuss the issues with Crane 1. The deck crane was examined. After the crane was inspected and operated, the hosting hydraulic motor was discovered to be the source of the issue. The hoisting motor was taken out, and the hoisting hydraulic motor was carried to the ship’s workshop. The lifting braking system and brake discs were also removed.
- In the workshop, the Alatas technicians disassembled the hoisting hydro motor. The piston was found to be cracked, and the piston bearing was also compromised. They discovered that there were no extra brake discs or pads after checking the ship’s inventory of spare components. Nine piston cylinder barrels and the retainer were changed. The components of the hydraulic hoisting motor were combined. The lifting hydraulic motor was then relocated from Crane 2 to Crane 1 by the technicians. The hydraulic system’s old oil was emptied when the technicians found metal residues in the hydraulic oil tank and system. The experts cleaned the filter and the hydraulic oil tank and then filled it with new oil.
- Since there was no spare brake disc or pad on board, the Alatas technicians took parts from the hoisting engine of the second crane on the final day of the operation. The uninstalled brakes were examined before being placed on crane number 1’s hoisting motor. The hydraulic motor for the lifting was reinstalled when the brake assembly was finished.
- Since the valves were completely closed during maintenance on the first day of arrival, the technicians made the pressure adjustment to the hoisting hydro motor from the valves. After checking the pressure settings, functional tests were carried out. The luffing, slewing, and hoisting functions of the crane were delivered in working condition.
- As mentioned in the delivery report, the maintenance by Alatas Turkey personnel resulted in a recommendation that the crane be operated without lifting heavy objects.
