The 493 Gross Ton Pusher/harbour tug Union Coral featured in this image was built in Spain in 2004 and when I saw her in April 2010 was Registered in Belgium. According to Internet sources (February 2023) she is owned and operated by the Company Union de Remorquage et de Sauvetage of Antwerp Belgium. When I saw her she was working in the Belgium Port of Zeebrugge.
