The Safmarine Nyassa monorail crane remove, refit & refurbishment
In focus: ✔Ship repairs ✔Afloat Repair ✔ Monorail crane repairs ✔Jebel Ali
The MV Safmarine Nyassa, a 210 m long cellular container ship owned and managed by Maersk Line, sustained considerable damage to its monorail crane due to contact with the ports gantry crane. Due to the tight schedule of the vessel it had to sail with the crane out of service.
Maersk Line contacted Albwardy Damen and sent the structural drawings of the crane along with photographs and class reports detailing the damage sustained and asked for a repair proposal. The repair procedure was prepared and approved by both Maersk and the Classification society, and the job was awarded to Albwardy Damen.
During the Safmarine Nyassa’s next scheduled port call to Jebel Ali, Albwardy Damen’s afloat repair team attended the vessel to remove the monorail crane from the vessel. This was completed by releasing the monorail crane and beam from its foundations and removing it from the vessel using two mobile cranes in tandem. Once the monorail crane and beam were safely removed, they were transported to our Afloat Repairs Workshop in Dubai Maritime City.
Albwardy Damen’s QC and Engineering Team then prepared the final repair plan and the monorail crane was stripped down, the electrical control wirings, hydraulic lines, wire ropes, etc. were all removed and renewed and the damaged sections of the crane beam were replaced. NDT was carried out as per class requirement.
During the next scheduled port call of the Safmarine Nyassa to Jebel Ali the monorail crane and beam was safely installed back on board again using Albwardy Damen’s trained riggers and banksmen using a tandem lifting technique with two mobile cranes.
Job was completed to satisfaction of the Client and the Class
