Flensburger managing director Rudiger Fuchs has been replaced after delays at the German shipbuilder.
The company said its owner, Siem Industries, has brought in one of its executives Alexander Gregg-Smith, who was in charge at the yard for six months in 2016, according to the NDR website.
Fuchs had been the boss since 2016, but the yard has been hit by delays to ferries contracted by Irish Ferries and Brittany Ferries in recent months.
