A Libyan-registered oil tanker, Alyarmouk, on Friday collided with a Singapore-registered bulk carrier, Sinar Kapuas, in Singapore waters, the Maritime and Port Authority of Singapore (MPA) said.
The collision happened about 11 nautical miles north-east of Pedra Branca. The MPA received the report at 6am, Singapore time.
The two vessels involved in the collision are currently anchored and in stable condition. There is no report of injury, and traffic in the port and the Strait of Singapore remains unaffected.
One of the Libyan tanker's cargo tanks was damaged, causing some spillage of crude oil. MPA has deployed a helicopter to assess the situation, and oil spill response resources have been activated.
MPA has issued navigational broadcasts for ships to navigate with caution.
As part of standard operating procedures for joint oil spill combat in the Strait of Malacca and Singapore, MPA has also notified the Malaysian and Indonesian authorities. MPA is investigating the cause of the collision.
