STAVANGER, Norway, Nov. 9 (UPI) -- Norwegian energy company Statoil said evacuating personnel from a listing workers' platform in the Norwegian Sea was orderly.
The energy company said it used helicopters to remove 336 workers from its Floatel Superior platform tied to the Njord field after the facility's ballasts failed.
Bente Aleksandersen, an emergency response manager for Statoil, said the rig was stabilized and personnel were evacuated without incident.
"While several people have described the incident and the evacuation as undramatic, we cannot rule out that others may have had a different perception," Aleksandersen said in a statement.
The Wall Street Journal reports the evacuation took place during rough weather and 32-foot seas. Norwegian authorities were investigating the incident, the second since September.
The energy company said it was conducting an internal investigation into the incident. The housing platform is on its way to shore for inspection under its own power.
There was no threat of an oil or natural gas leak from the incident, the company said. Statoil said only security staff remained on the Floatel Superior.
