An organic product reportedly escaped from a vessel at the Delwaide dock overnight on Sunday.

AIS data showed the 4,132-teu MSC Ulsan (built 2002), managed by Shanghai Costamare Ship Management, berthed in the dock on Monday morning.

But Costamare told TradeWinds there had been "no accident whatsoever" involving its ship.

Authorities said there was no danger to the surrounding area.
