Authorities in Singapore are investigating a collision between a ferry and a chemical tanker in the country’s waters.

A Singapore-registered passenger ferry and a Marshall Islands-registered tanker collided off the Southern Islands on November 10.

The Maritime and Port Authority of Singapore (MPA)) said it has launched investigations on a collision between the ferry Horizon 9 and the tanker La Digue.

According to the MPA, the ferry was en route to HarbourFront Centre when the vessels collided off the Southern Islands. The incident occurred on November 10 at about 5 p.m. (local time).

An MPA patrol craft was deployed to escort and guide the ferry back to HarbourFront Centre.

All 165 passengers and 7 crew on board Horizon 9 were safely disembarked at the Regional Ferry Terminal at HarbourFront Centre, according to reports from the MPA.

The ferry sustained some damage to its bow above the waterline but remained fully operational while en route back to Harbourfront Centre, said MPA. The 50281-dwt chemical/oil products tanker, built in 2011, did not report any damage.

MPA confirmed there were no injuries to passengers and crew, no pollution, and no impact on navigational traffic or port operations.

MPA said it is conducting an investigation into the cause of the collision.
