ENI developed the innovative concept together with their consortium team Project PosHydon<\/em>. In collaboration with SEW Energy, they realized this concept.<\/p>\n

The project began at the onshore test site in Alkmaar, where a fully functional setup was built with all the necessary components. A key component, the 16 by 8 meter base frame, was manufactured in the SEW production hall in Broek op Langedijk. This frame, with a total weight of approximately 80 tons, was then transported in sections to the Investa test site, where all the components were assembled.<\/p>\n

After a successful test phase, the complete installation, spread over eight trucks, was transported to Den Helder and loaded onto an offshore supply vessel for transport to the offshore platform Q13-A.<\/p>\n

Thanks to the close collaboration between SEW Energy and ENI Energy, the entire installation was erected on the platform within one week, an impressive achievement that underlines efficiency, craftsmanship and teamwork.<\/p>\n

Project PosHydon demonstrates how innovative ideas, technical expertise, and multidisciplinary collaboration come together to make complex projects successful, both onshore and offshore.<\/p>\n

The challenge<\/strong><\/h4>\n

The PosHydon project is one of the first initiatives worldwide to test hydrogen production at sea. This presented not only technical challenges but also strict requirements regarding safety, transport, and the integration of various systems. SEW Energy was asked to support both the preparation and implementation, both onshore and offshore, and to oversee the entire process until handover to the client.<\/p>\n

SEW Energy brought together various disciplines to realise this innovative project:<\/p>\n
