Nov 7 - Energy firm Statoil evacuated an accommodation rig at the Njord oil and gas field in the Norwegian Sea on Wednesday after it tilted up to 4 degrees, the Petroleum Safety Authority (PSA) said in a statement.

"The PSA received notification of the incident at 04:15 (0315 GMT) in the morning stating that an anchor had punctured one of the ballast tanks and as a result, the facility was listing 3-4 degrees," the watchdog said.

Statoil in response evacuated the 374 people from the Floatel Superior rig, owned by Sweden's Floatel International AB, PSA said.
