Main tasks of the Legal/Permitting Advisor involve the drafting and legal review of the joint venture agreements for the operated assets and also the contractors’ operational agreements. These contracts should be legally sound and save, and foremost reflect the operating practice. Nineteen years of experience in the industry comes in useful. Hanneke’s master of Laws at Leiden University with a major in administrative law, was obtained during her job at Wintershall, synchronising law and practice. Operations cannot be undertaken without a set of permits. ONE takes special care if the activity is located in a sensitive area. An evaluation of the impact on environment and nature forms part of the permit application. Here her first professional education is beneficial, as a BSc in Landscape/Nature Management gives ample insight on the mechanics of an ecosystem. In her spare time Hanneke likes to swim and design and create her own clothes. She has an interest in art, nature and history.
