Damaged Jib Repair in Istanbul

Alatas Turkey was contracted to repair jib on an NMF DK VS 30028 ship crane. Our experienced service engineers dismantled the damaged crane boom to be repaired in our Alatas Workshop in Instanbul. After the boom removal, the engineers carried out an inspection and found heavy rusting on the jibs and sheaves. The boom mounting bolts were also heavily corroded and couldn’t be removed by hi-torque.

Our technicians carried out work with the vessel captain’s sign-off. The first task was to cut and remove the boom mounting bolts by an oxy-acetylene flame cutter. Then the rusty sheaves connection bolt was cleaned and maintained. Next, our engineers cut and removed the thin boom connection point and rope fixing pin, and they also produced a new connection point and pin. Finally, all rusty parts had cleaned and repainted.
