The chief executive of A.P. Moller-Maersk, Nils Smedegaard Andersen, returned to work on Monday after recovering from heart surgery, the company said.
Andersen underwent surgery to replace a cardiac valve at the end of December 2011 and a further corrective operation on March 28.
"Having participated in a number of meetings and having been updated on our activities during the last couple of weeks, I am now ready to return to work," Andersen said in a statement.
“The company continues to be full of strength while I was absent,” Andersen said. “There’s a lot of activity in our markets and lots of initiatives and challenges that I look forward to handling together with the rest of the management team and our employees.”
