The technicians of Alatas Turkey were on the vessel to troubleshoot the deck crane.


The technicians of Alatas Turkey traveled to Bursa, Gemlik, and attended to the vessel. They carried out the visual assessment of cranes 1 and 2 and then got to work on the concern.


  • The Alatas Turkey technicians checked the spare parts first after tending to the vessel. For cranes No. 1 and 2, a visual check was next conducted. They examined Crane 2 and discovered that the solenoid valves, control block, check valves, and accumulators were all rusted and broken. They advised replacing some of the hydraulic hoses with new ones because some of them were leaking and broken.
  • Crane 1 and 2 were checked to compare valve positions and decided one valve position was different.
  • Q01’s electrical panel was malfunctioning. Q01 had to close and open again when the crane’s power was restored, which was not how it should have been operating. Hence the specialists suggested renewing with a fresh one.
  • The technicians checked the relief valves and saw they were rusty and damaged along with the hoses of the relief valves.
  • They observed that the block of the relief valve was rusty and damaged. The flexible hydraulic hoses were leaking and damaged. They recommended replacing it with a new one as a result of these.
  • The Alatas Turkey technicians checked the crane 1 limits and adjusted some off-limit switches to remove the hook from the hook garage. Once the hook was taken out of the hook garage, the crane was examined, and it was discovered that crane no. 1 was in good working order without the replacement of various parts and limit switches.
  • Then they checked the Crane 2 hook issue and saw the hook-down limit was not adjusting correctly. After adjusting the limit switch and connecting the contactor electrical cable, the hook issue in crane no.2 was solved. And they observed that one of the slewing motor’s gear oil levels is low in crane no.2.
  • The following day they attended to the vessel again, they checked Crane 2 and saw the limits were not working correctly. So they adjusted the limit switches.
  • For the problem with crane number 2, the technicians examined the emergency lowering valve and discovered that it was tight.
  • They examined the valve positions, and they determined that one valve position had been installed incorrectly.
  • During testing crane number 1, it was discovered that the corrected limit switches were missing.
  • They adjusted and checked the limit switches again. When the limit switches were tested, again all switches were seen missing. The specialists suggested replacing every component of the limit switches with new ones.
  • To ensure that the hook garage sensor was in working order, it had to be examined. They noticed that crane no. 2’s foot bearing made an unusual sound.
