The ‘Circular Explorer’ is the latest waste collection ship from oeoo. It was implemented in cooperation with Holcim, a global leader in innovative and sustainable building solutions.
Formerly called ‘SeeKuh II’, the project was launched in Lübeck in 2019 and is a completely redesigned collection ship. The collection system of the ‘Circular Explorer’ is no longer based on lowerable nets, but on conveyor belt technology. Via deflectors at the bow of the catamaran, the marine litter is directed onto the conveyor belt mounted in the middle. The ascending belt continuously conveys the material onto a horizontal sorting belt. Everything that does not belong in the sea is sorted out manually by the sorting staff and collected in transport bags, so-called big bags. Harmless organic waste falls back into the water at the end of the conveyor belt through an opening in the deck. In this way, oeoo expects a higher efficiency and at the same time the sorting out of organic material and possibly animal by-catch is possible.
As SeeKuh I the ‘Circular Explorer’ has a modular design, so that it can be dismantled and transported in sea containers to any place in the world. The ‘Circular Explorer’ is 12 metres long and about 8 metres wide. This means that it can be stowed in only 2-3 overseas containers. The draught is only 0.8 metres and the weight is six tonnes. Its cleaning capacity is about 30,000 m²/h.
‘Circular Explorer’ is the world’s first waste collection ship of this size to be powered entirely by solar energy. Vertically and horizontally swivelling solar modules are mounted on a so-called carousel, which can be aligned with the sun.
The system can fully charge the two batteries with 32 kW within one day, as used in a BMW i3.
