In July 2022 Global Rigging and Transport were given the challenge of relocating a Liebherr Mobile Harbour Crane from Portland, Maine along the coast to Eastport, Maine. Eastport has a 22’ tide, which meant GRT were required to utilize their ballast system to counteract the dropping tide.
Global Rigging and Transport undertakes many projects that involve ballast operations and have a fully containerized ballast system, with a total capacity of 7600-tons per hour. They were able to provide an engineered ballast plan and ballast technicians along with all the ballast equipment for making the loading and unloading of the crane a smooth operation.
The ballast system consist of twenty 6" electric submersible ballast pumps. The twenty pumps are operated by four central control kiosks and the system is capable of handling complex loading and unloading operations, including extreme tidal situations. This is exactly what was needed during the critical offloading operation of the Liebherr Crane, along with the GRT barge mooring system, which kept the barge close to the dockside at it's initial location. Essential because during the preparation stages of the offloading operation, GRTs onsite engineers recorded a drop in water elevation of 19” in 20 minutes.
