During vessel operations in Chile the vessel developed damage to the Tsuji crane winch; drive shaft, brake and internal gearbox. The customer requested that the winch from crane #2 be relocated to crane #4.
In consultation with Tsuji the procedure for winch removal was agreed. The hoisting winches were rotated through 90° and removed. The hoisting winch was removed by crane #3 and placed on the portside deck. The winch drum and gearbox was removed from the winch drum, and the winch boxed for transportation to shore workshop.
The winch from crane #2 was removed and installed into crane #4. Hydraulic and electrical set up was carried out to the relocated winch, and function tests were carried out to the Tsuji crane.
