Wıre Rope Change Out in Yalova

BACKGROUND

The Alatas Turkey technicians made the necessary preparations for the wire replacement of the hose-handling cranes. They removed the old wires in the starboard and port side hose cranes and transferred the new wires to the cranes. After the equipment of the new wire hose cranes has been completed, the wire winding process has started. The length and thickness of the new and old wires were measured, and the new wire crane was installed. The old wire on the starboard supply crane was removed and mounted on the new 16mm Q 250m wire. The new wire of the pier hose crane was laid on the deck, and length and thickness measurements were taken and mounted on the crane. After checking the damage on the wire rope, it was replaced with a new one.

ALATAS’ SOLUTION

The Alatas Turkey technicians made the necessary preparations for the wire replacement. They made removal and transfer. The measurements and mounting have been made.

FULL WORK SCOPE

The Alatas Turkey technicians traveled to Yalova and boarded the vessel. They met with the shipyard engineer and then made the necessary preparations for the wire replacement of the hose-handling cranes on the starboard and port side. New wires were supplied by ship. The technicians removed the old wires in the starboard and port side hose cranes and then transferred the new wires to the cranes by the crew. The technicians determined that no label shows millimeters and meters on the new rope. After that, the Alatas Turkey technicians completed the equipment of the new wire hose cranes and started the wire winding process. During the hardware, it was determined that the new wire was long and stuck to the upper limit. A meeting was then held with the shipyard engineer. As a result of the interview, it was determined that there was an error in the dimensions of the new wires, the old wires were laid on the deck, and the lengths of the new and old wires were compared. This procedure was performed for each crane. The technicians removed the new wires in the starboard and port hose cranes. The technicians of Alatas Turkey laid the old wire of the starboard hose crane on the deck, measured the length and thickness of the new wire and the old wire, and installed the new wire crane. Then C/O lower and upper limits were checked, and no problem was found. The old wires on the starboard and port sides were removed and laid on the deck, new wires were laid next to them, and their thickness and lengths were measured.

A total of 18mm 200 meters of rope,18mm 100 meters on the right, and 18mm 100 meters on the left in the starboard lifeboat were put on pulleys, tied to the drum, and delivered to the crew.

In the port side lifeboat, 18mm 200 meters of rope, 18mm 100 meters on the right, and 18mm 100 meters on the left were put on pulleys, tied to the drum, and delivered to the crew.

On the other day, after the meeting with the shipyard engineer, the Alatas Turkey technicians laid the old wire of the starboard hose crane on the deck, measured the length and thickness of the new wire and the old wire, and installed the new wire crane. Limits have been lifted, and a new rope was attached to the crane and tested by ship personnel. The technicians removed the new wire in the port hose crane and determined that the wire feeding the wire was defective, and the newly removed wire was the starboard supply crane. The technicians removed the old wire on the starboard supply crane and mounted it on the new 16mm Q 250m wire. Then the technicians laid the new wire of the pier hose crane on the deck, and length and thickness measurements were taken and mounted on the crane. The 18mm thickness of the new wire was determined as 180 meters. They removed the rope of the engine room crane, and they determined that it was 14mm thick and 83m long. The Alatas Turkey technicians reported to C/O that there is no new wire of the same size and that the new wire will arrive tomorrow.

When the new wire sizes were different from the old ones, they were installed on the crane upon the client’s insistence. It was shown to the customer that it is not compatible with the installed 16 mm 90 m wire spool. The new wire is requested to be the original wire.

The technicians laid 14 mm 90 m new wire in the engine room, and its length was measured and cut to 83 m. The new wire is passed through the reels and connected to the drum. Limit and load sensor settings were completed, and the shipyard engineer signed the delivery report.

The new wire was damaged while the ship’s crew was using the portside hose winch.

The port side new wire was damaged because of an improper operation. After checking the damage on the wire rope, it was replaced with a new one.
