P&ONL facilitates Rotterdams mating game
Every fortnight vessels of P& O Nedlloyds container fleet take fresh seawater from the Atlantic to Rotterdam in their ballast tanks. While the ship is worked at the terminal, a small tanker comes alongside and the water is pumped aboard from the bigger ships tanks. The tanker sails to Rotterdams zoo where the seawater is used for refreshing the water in the Oceanium, home of the zoos fish, sharks, coral, penguins, etc.
P&O Nedlloyd takes 300,000 litres to Rotterdam free of charge using13 ships from its Far East and Atlantic services.
The Oceanium contains some 7 million litres of salt water and the zoo is enthusiastic about the quality of the Atlantic water.
Even sea horses and coral reproduce in it apparently, which they seldom do in a zoo.
