Workers taken off production vessel in North Sea after 'incident' Around 20 workers have been moved off a North Sea vessel in the wake of a "minor incident" on board. Dana Petroleum confirmed smoke and sparks were seen coming from the coupling on an emergency generator at its Triton floating production, storage and offloading vessel at 11.40am on Monday. It was put out "immediately" using a hand-held fire extinguisher and no one was injured, the firm said. Dana said around 20 of the 79 workers on board on Monday were moved off the vessel on Tuesday as part of normal crew change because of the loss of some power, not due to safety concerns. A spokesman said: "As a result of the incident, a number of crew returned onshore during normal crew rotation today due to the loss of some platform services. The platform is currently shut down for maintenance. The relevant authorities have been informed in line with normal procedure. Dana Petroleum takes the safety and welfare of its employees and contractors very seriously and will conduct a full investigation into the incident.
