Canada's Teekay Corp has so far managed to keep Covid-19 off nearly all its vessels - bar two cases on a North Sea FPSO.
Speaking on a conference calls with analysts, chief executive Kenneth Hvid said the tanker and LNG carrier fleet had been coronavirus free, thanks to its employees' dedication to health and safety.
"We unfortunately did experience two Covid cases on the Hummingbird FPSO, but after a deep clean and full crew change we were able to fully restart operations and have had uninterrupted operations since," he added.
