About Blommaert & Wattlab


In 1978, Blommaert started with the design and production of hatches made of aluminum for inland shipping. Four decades later, they have become market leader. Blommaert delivers an extensive range of solutions for inland shipping, mobile roofs on land installations, and aluminum constructions for industry.


Wattlab develops custom solar energy systems. Wattlab's originated from the Vattenfall Solar Team, a multiple World champion team with solar car Nuna. Building on their expertise, they now bring solar technology to inland shipping.

Our mission

Our mission is to make inland shipping more sustainable while also creating independence for the captains and crews. In the coming years, we will see transport ships and barges sail increasingly emission-free. Which, even idle, can deliver green energy to companies and households in the neighbourhood. In this way, we are transforming inland carriers into floating solar parks.
