GERMAN giant, Hansa Heavy Lift, has shipped 13 modules sized more than 147,124 cubic metres from China to Australia to help redevelop Port Pirie’s Nyrstar Smelter.
According to a statement, the cargo was loaded on four separate voyages at the Yanda Module Yard in Jiangsu, China.
The largest piece weighed 690 metric tonnes, measured 28 metres in length and was 17 metres wide and 26.7 metres high.
“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,” said Henry Woo, head of Asia-Pacific for HHL.
“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.”
The decks of each vessel were reportedly extended to the aft and in some cases even to the starboard side to accommodate up to five modules a trip.
The large cargo required additional bow radars and extra crew on bridge watches.
The cargo had to be especially lashed and secured due to the sensitivity of the structures and expected rough seas.
This required new types of sea fastening that had to be tested and certified.
Other measures were put in place to reduce the impact of the obstructed view from the wheelhouse.
Crews also faced strict draft limitations and narrow navigation channels on both ends of the voyages.
Crews had to deal with temperatures of up to 45ºC when they arrived in Port Pirie.
“We are proud to have completed the project with a smooth execution at every stage, resulting in a safe and on-time delivery of all modules,” said Jens Grever, head of cargo management, Asia, HHL.
The Port Pirie Redevelopment Project is to convert one of the world’s largest primary lead smelting facilities into a multi metals processing and recovery facility.
Geodis project coordinator, Ben Williams, said HHL showed a “very high level of engineering expertise and professionalism” throughout the entire process.
“Hansa Heavy Lift took every detail into consideration, as well as keeping a clear and open line of communication throughout, once again proving themselves to be a reliable super heavy lift partner.”
HHL specialises in the super heavy lift 900+ tonnes industry, delivering engineering solutions to customers, particularly in the subsea, oil and gas, as well as for offshore wind farms.
