Hansa Heavy Lift has transported 13 modules measuring over 147,124 cbm from China to Australia, to help with the redevelopment of the Nyrstar Smelter in Port Pirie. The cargo was loaded on 4 separate voyages at the Yanda Module Yard in Jiangsu, China, with the largest piece weighing 690 metric tonnes and measuring 28 meters in length, 17 meters in width, and 26.7 meters in height.
• The decks of each vessel were extended to the aft and in some cases even to the starboard side to accommodate up to 5 modules per trip.
• The over dimensional cargo required the installation of additional bow radars and the extra crew to double up bridge watches.
• Due to the sensitivity of the structures and expected rough seas during the voyages, the lashing and securing of the cargo represented another challenge.
The Port Pirie Redevelopment Project will convert one of the world’s largest primary lead smelting facilities, operated by Nyrstar, to a multi metals processing and recovery facility.
► Henry Woo, head of Asia-Pacific (APAC), Hansa Heavy Lift, said:
“This was a particularly challenging project which required the use of three of our vessels on four separate trips operating at their full capacity, including HHL New York, HHL Lagos, and HHL Valparaiso. Lifting and rigging were particularly challenging for this project due to the height of the modules combined with the offset centre of gravity, with up to five lifting beams required for a single lift. Our team of in-house engineers managed this by developing innovative rigging solutions as well as enacting a careful loading and engineering plan.”
