Connecticut-based Chembulk Tankers will have a new CFO from 1 May.
Bart Kelleher will replace John Capasso, who is resigning to pursue other career opportunities, the company said.
Capasso has been with the owner since May 2017 and has played a key role, it added.
Kelleher, Chembulk's chief strategy officer since early 2016, will see his job expanded to include finance and accounting functions as well as corporate strategy.
