INTRO

Alatas Turkey technicians commenced Crane troubleshooting right after tending to the vessel. They gauged the voltage of the hoisting joystick potentiometer. They replaced the joystick cable head and repaired the connection sockets of the MPC cards. Following a Crane assessment, the technicians put forth some suggestions.

BACKGROUND

The customer contacted Alatas Turkey to troubleshoot the Crane.

ALATAS’ SOLUTION

The technicians from Alatas, Turkey, conducted measurements, performed renewal and repairs, and carried out testing based on their observations.

JOB SCOPE

Initiating the troubleshooting process, Alatas Turkey’s technicians measured the voltage of the hoisting joystick potentiometer, registering it at 6V; however, this voltage exhibited fluctuation.

Upon visual inspection, these technicians detected corrosion affecting the hoisting cables and sockets. In response, they proceeded to replace the head of the hoisting joystick cable while simultaneously ensuring secure connections.

The team from Alatas Turkey also undertook the task of rectifying the MPC card connection sockets, meticulously mounting them in their proper positions.

Thorough testing, in accordance with project guidelines, was carried out on both the CT2 panel and cabin joystick connections, with careful scrutiny of each connection point.

Notably, wear was discovered within the zero positions of the joystick and its mechanical springs. This wear contributed to a joystick level fault as well as a disruption in the Pulse Width Modulated output signal. (The examination aligned Code 61 with Code 60, and Code 76 with Code 74, as specified in the manual.)

Advancing forward, the technicians from Alatas Turkey initiated the testing of Crane no. 3, collaborating closely with the vessel’s crew. Following a series of assessments, they proceeded to offer specific recommendations before ultimately delivering the crane in a fully operational state.
