Chevron Nigeria Ltd. called off the search and rescue activities for two contractors who were missing after the fire that started Jan. 16 aboard the K.S. Endeavor, a drilling rig offshore Nigeria operated by FODE Drilling Nigeria Ltd.

After three days of intensive search and rescue activities for our missing colleagues, I am saddened to report that our efforts have proven unsuccessful and, therefore, we have made the difficult decision to transition to a recovery operation. On behalf of Chevron, we extend our sincere condolences to the families of the missing individuals, said Andrew Fawthrop, managing director, Chevron's Nigeria/Mid-Africa Strategic Business Unit.

Chevron reported that it is continuing its plans and preparations to drill a relief well along with its investigation into the cause of the incident.

The company confirmed that 152 workers on the shallow water rig and associated barge were safely evacuated from the incident, which occurred about 10 km from shore. Two workers who received medical care for burns have been released from the hospital.
