Mammoet proposed a new wireless weighing technology as it provided the most cost-effective and efficient approach for the weighing scope, in turn benefitting the overall project schedule.
For the task of weighing 60 modules one-by-one, having wireless load cells provided efficiency and reduced congestion onsite while improving safety. Without wires, there were fewer obstacles and potential hazards on the work site. Setting up the system took less time, because there were no wires to run. Prior to the start of the project, Mammoet worked with the wireless weighing technology fabricator to slightly modify and customise their design, in order to meet Mammoet requirements.
The weight of the modules varied between 30t and 175t each, and the heaviest module was 105ft x 53ft x 30ft x 384,000lbs (32m x 16m x 9m x 175t). Over the entirety of the project, 72 axle-lines of SPMTs were used to transport the weighed modules onto barges.
Modules were divided into 18 barge shipments, which were loaded over a period of ten months. Due to a tidal difference of up to 16ft between high and low tide, only one module was able to be loaded per day before the tide would again be too high to safely execute barge loading. Despite the tide and frequently uncooperative weather, Mammoet was successful in completing the project a week ahead of schedule, on budget and incident free.
