Last year I visited the harbour Eemshaven near my QTH and made some photos from the largest pipe lay crane vessel of the world. It has gone away but when my wife and daughter visited the Eemshaven today this monster was just towed into the harbour again.
This thing is huge. Look at the size of those tugs. Four of them guiding it into the harbour.
Speaking about huge. My antennatower has finally moved to another place for the time being after 8 years into the mud and grass in the garden.
