Danish tanker and bunker group United Shipping & Trading Co (USTC) has completed its generational shift with the appointment of Mia Ostergaard Nielsen to an operational role.

The executive is the second daughter of chief executive and founder Torben Ostergaard-Nielsen to join the company after her sister, Nina Ostergaard Borris, 37, who is chief operating officer.

The daughters were made joint owners with their father last year.
