Huisman informed that it delivered the first ever class certified, 3D-printed crane hooks. The 3D-printed hooks were certified following load testing at more than double their safe working load. The hooks are certified for offshore use based on ABS standards.
The OOS Serooskerke will be the first ship to have a 3D-printed crane hook installed. In addition, the OOS Walcheren will also have a 36 tonne SWL 3D-printed crane hook. Huisman produced both of the hooks.
Huisman researched the 3D-printed material’s qualities, taking into consideration strength and fatigue. It also examined it for potential anisotropy, meaning different material properties in different dimensional directions.
Before that, in 2018, Huisman successfully tested the 3D printed offshore crane hook to 80 tonnes, before ending up installing the first 3D-printed crane hook globally.
