First ever 3D-printed crane hook installed on OOS Serooskerke
Huisman is proud to have delivered the first class-certified 3D-printed crane hooks. After load testing at more than double the Safe Working Load, the 3D printed hooks were certified for offshore use according ABS standards.
OOS Serooskerke will be the first vessel ever in history on which a 3D-printed crane hook is installed. Also her sister vessel, OOS Walcheren will be equipped with a 36mt SWL 3D printed crane hook. Both hooks have been produced at Huisman’s Czech Republic facility.
Currently, crane hooks are manufactured by casting or forging techniques. Delivering these class-certified 3D printed hooks to an end client is an important step in developing industry acceptance for 3D-printed products for the maritime and offshore industry. Already back in January 2018, Huisman successfully load tested the world’s first 3D printed offshore crane hook to 80mt. An important benefit for larger crane hooks is the significant reduction in delivery time at a cost that competes with forgings and castings, and a consistent level of quality.
From Master thesis to working product within two years. It reads like a novel, Hugo Romer wrote his TU Delft Master thesis at Huisman on “Wire & Arc additive manufacturing for offshore appliances”. Won the KIVI Offshore Engineering award for the best student who graduated in an offshore engineering related topic. Started as Engineer at the R&D Department at Huisman the Netherlands but was soon transfering as Supervisor Test Centre to Huisman China to transform the 3Didea from the drawing table into a working, realiable crane hook.
The Huisman R&D team researched material qualities, among which strength and fatigue, and the possible anisotropy of the material. That work has been carried out at Huisman, partly in Schiedam and partly in the Czech Republic. Finally leading to the first ever installed 3D printed crane hook in the world.
