Ampelmann’s motion compensated cranes operate in a dynamic environment resulting in high loads on the crane. This MSc thesis aims to get more insight in the structural dynamics of an Ampelmann crane. With your research we aim to increase the rating of our cranes or decrease the weight of our structures! Interested? Read more below or apply via the “apply now” button!
Ampelmann makes offshore access as easy as crossing the street. Our drive is to make offshore access safer, enable the energy transition and have a great career in the meantime. We combine the challenges of a large globally operating organisation with a change-positive attitude and entrepreneurial spirit. Personal development and having responsibility take centre stage at Ampelmann.

About the Innovations department
The assignment is performed for the Innovations department, responsible for developing conceptual ideas into tangible products and services to serve our clients' needs. You will be part of the Basic & Detail (B&D) engineering team. Basic & Detail engineers make it real and ready for operation! The B&D team is a multidisciplinary team of 16 engineers, covering fields of Motion Control, Structural and (Mechanical) Design. Engineers are grouped in various project teams, to focus on delivering new solutions for our clients. You will be supervised by a structural engineer of the B&D team and you will be in contact with the structural engineering community.
Ampelmann currently develops cranes that are used in the maintenance phase of a wind farm. Due to the dynamic environment these cranes operate in, a dynamic factor is typically applied on the hoisting load. These cranes typically lift a load up to 5mT, which is low load compared to other offshore cranes and will result in high dynamic factors. The consequence is that the rating of the crane, or the weight of the structure, are affected.
The dynamics involved with a load pickup are shown in the figure below, where the peak load can be as high as 2 times the hoist mass.
Ampelmann aims to research crane dynamics with the goal of reducing weight of our systems or increase the rating of current cranes. The idea is to reduce the dynamic factor by performing advanced simulations and/or implementing control solutions. The novelty in this assignment is to develop a method combining the motion compensation control system with structural dynamics.
The goal of the assignment is to deliver a calculation method for the dynamic analysis of a crane that can be used during the design phase.
This assignment requires the following research/analysis to be done:
The assignment is performed for the innovations department, which designs and delivers new innovative Ampelmann systems and services. You will be supervised by a structural engineer of the basic/detailed team and be in contact with the structural engineering community.
