MacGregor, part of Cargotec, will deliver two large, 120ft double telescopic service cranes and one 50ft telescopic crane for a self-propelled hopper dredger, currently being built for Manson Construction.

The new vessel, to be named Frederick Paup will be the largest self-propelled trailing suction hopper dredger built in the USA and will operate nationwide. The order was placed by Keppel AmFELS. The cranes are planned to be delivered to the yard by the end of 2021, with commissioning and testing during 2022 prior to delivery of the vessel in spring 2023.

The larger service cranes are double telescopic cranes with a size of 80ft length when stored and extend out to 120ft. The Safe Working Load (SWL) for these cranes will be circa 3,900lbs at 120ft and 108,000lbs at minimum reach. The aft stores crane is a single telescopic crane with a size of 32ft length when stored that extends out to 50ft. This versatile model has been installed on a diverse range of vessels in recent years, including a number of fishing vessels in the US Pacific Northwest.

MacGregor worked with the vessel owner/operator, Manson Construction of Seattle, WA, and the designer, Hockema Group of Seattle, WA, during the earlier design stage of the project to provide crane models that fit the requirements and ensure highest quality. The cranes will be built at MacGregor’s facility in Seattle, and the vessel will be built at Keppel AmFELS US shipyard in Brownsville, Texas.

 Jordan Brown, Project Manager, Manson Construction, said: “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.”

Leif Byström, Head of MacGregor’s Offshore Solutions Division, said: “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.”
