At least four people have died after a helicopter transporting workers to an offshore Angola oil platform went missing.
According to Reuters, a helicopter departed from Malongo port on Monday around 3:30 p.m. local time to transport workers to the Tombua-Landana offshore platform.
The helicopter never arrived at the Chevron-operated platform, Reuters said.
Chevron told Reuters that four of the people aboard the helicopter died as a result of the accident.
Two other passengers are still missing.
The helicopter was carrying four contractors, one Chevron employee and a pilot when it departed from the port, located in the Cabinda province.
The company has deployed 19 marine vessels and three helicopters to conduct search and rescue operations.
Chevron did not comment on whether the search operations will impact its oil and gas activities in the area.
No further details about the incident have been disclosed.
Chevron Corporation, through its subsidiary Cabinda Gulf Oil Company, began crude production at the 100,00 barrel per day Tombua-Landana project in 2009.
The platform is located 50 miles off the coast of Angola is Block 14.
