The document describes the transport and installation of two hydrothermal reactors, weighing 750 tons and 215 tons, at Neste Oil's NExBTL plant in Rotterdam. A 750 ton reactor was transported from a ship using cranes and secured onto specialized transport vehicles, then moved to a storage site. A 215 ton reactor from another ship was also lifted, secured, and transported to the plant site where both reactors were positioned for installation.
