A link to join the webinar will be sent shortly before the event.

Heerema Engineering Solutions (HES) is an Energetic & Independent Engineering Company located at the Buccaneer in Delft. We translate deep theoretical knowledge into working offshore methods.

Multiple projects currently investigated within HES are related to the installation of XL Monopiles offshore. Jelle ter Braak is an Offshore engineer currently working as a package engineer responsible for the control design of a motion compensated gripper frame.

Jelle graduated from the Delft University of Technology with a MSc degree in Offshore and Dredging Engineering. After his research at Allseas Engineering B.V. he started his career at Heerema Marine Contractors. At HMC and HES, Jelle has worked in Decommissioning as a Structural Engineer and contributed to the development of several engineering software packages such as an inhouse developed finite element package.

For his Master  Systems and Control (TU Delft), Job Schepers is doing his graduation project at Heerema Engineering Solutions (HES) focusing on the installation of XL monopiles offshore.
The topic of his thesis is the design of a motion compensation gripper frame. In order to control the position and angle of the monopile during the installation a control system has to be designed. Changing soil properties, vessel motions and wave disturbances influence the system dynamics, resulting in a complex control problem.
During this lunch lecture he will talk about the motion compensated gripper as one of the solutions for the next generation of offshore wind turbines.
