SCHIEDAM, the Netherlands – The Wei-Li crane ship has departed the Damen Shiprepair Dunkerque after 10 days of maintenance and repairs and is on its way to Rotterdam. The 463-ft (141-m), 18,330-dwt crane ship required special dock bed arrangements.
A total of 225 blocks were required, along with an additional 56 steel pillars of up to 23 ft (7 m) in length to support the stern. Wooden wedges also had to be added to the lateral blocks to take account of the unusual hull shape and to ensure complete stability in the drydock.
The scope of work over the 10-day period included, along with the standard work for class survey, blasting and painting the hull and the overhauling of the internal and overboard valves. The scope of the electrical works was extensive given the tight time frame, with a large number of motors removed and transported back to workshop for overhaul before being returned and refitted. The last ones were fitted and tested on the same day of the vessel’s departure.
The Wei-Li was built by Zhenhua Heavy Industries in 2010 and this summer was involved in the installation of the 11,000-metric ton jacket for the Ivar Aasen project in the Norwegian sector of the North Sea.
