Manson Construction Company’s 15,000-cubic-yard capacity, 420 foot long, hopper dredge Frederick Paup is to be equipped with MacGregor telescopic cranes.
Currently under construction at the Keppel AmFELS shipyard in Brownsville, Texas, the vessel will be the largest self-propelled hopper dredge in the U.S, on delivery.
MacGregor, part of Cargotec, will deliver two 120 foot double telescopic service cranes and one 50 foot telescopic stores crane for the vessel.
The cranes will be built at MacGregor’s facility in Seattle, Wash, and are planned to be delivered to the shipyard by the end of 2021, with commissioning and testing during 2022 prior to delivery of the dredge in spring 2023.
The larger service cranes are double telescopic cranes with a size of 80 foot length when stored and extend out to 120 foot. The Safe Working Load (SWL) for these cranes will be circa 3,900 lbs at 120 foot and 108,000 lbs at minimum reach. The aft stores crane is a single telescopic crane with a size of 32 foot length when stored that extends out to 50 foot. This versatile model has been installed on a diverse range of vessels in recent years, including a number of fishing vessels in the U.S. Pacific Northwest.
MacGregor worked with Manson and the designer, Hockema Group Inc. of Seattle, during the earlier design stage of the project to provide crane models that fit their requirements and ensure the highest quality.
“Since day one, the MacGregor team has provided excellent support and engineering solutions for this project, and the cranes will be a great tool for our daily operations,” says Jordan Brown, project manager, Manson Construction Company.
Leif Byström, head of MacGregor’s Offshore Solutions Division, says, “The active dialogue at an early stage in the project, together with the operator’s focus on high-quality equipment and reputable in-service support, are the reasons why MacGregor was selected to supply these robust cranes.”
