The niece of Bourbon's CEO and chairman Jacques de Chateauvieux is the French offshore giant's new CFO.
Astrid de Breon will join on 1 February following the recommendation of the nominating, compensations and governance committee.
She will leave the board at the same time.
De Breon is the daughter of Henri de Chateauvieux, Jacques' brother, who has 7.6% of the shipowner.
A graduate of the ESSEC Business School, the 37-year-old has previously worked at BNP Paribas, first as a project manager for finance management and then head of corporate strategy.
Since 2014, she has been in charge of institutional and corporate clients at the Business Center Paris Etoile Entreprises.
“Thanks to the benefits of the digital revolution, the business model of Bourbon is led to evolve," said Jacques de Chateauvieux.
"The CFO will not only bring innovation to the heart of the financial strategy but also accompany the strategic transition of the company. I am convinced that Astrid will bring value to this transformation within the general management team in compliance with the values of Bourbon."
