The eastern Libyan oil ports of Es Sider and Brega have been closed due to bad weather but crude production has not been affected, an official from state oil firm NOC said.
Storage capacity is sufficient for a few days and the remaining ports were open, the official said.
Tankers were waiting to dock at Es Sider and Brega, port sources said.
A shipper's note and a port engineer said the other eastern Libyan ports were also closed.
A similar closure this month led to a temporary reduction in production by Waha Oil Co as storage capacity at Es Sider was limited after some tanks were damaged during clashes last year.
