LyondellBasell is one of the world’s largest producers of plastics, chemicals, and refining products and a global leader in their field. Their Wesseling site near Cologne plays an important role in their supply chain. To make space for larger ships and ensure year-round unloading of naphtha, even during low water levels, LyondellBasell needed a major upgrade to their jetty infrastructure. We got hired to replace their old floating jetty with a new, fixed jetty of 140 meters long and 500 tons.
Demolition and removal of the existing jetty S002
Construction and maritime installation of the new jetty S002
Basic and detailed design for E&I scope
Sourcing, purchasing and expediting of necessary equipment
Placement of various equipment, including a loading arm
Design and installation of electrical systems and instrumentation
The existing floating jetty was no longer suitable for the increasing demand and larger vessels. LyondellBasell chose to build a new, 140-meter-long fixed jetty that would allow year-round operation. Time management was the biggest challenge: everything had to be finished within 15 months. This was especially challenging when we had to adjust the scope and planning several times due to external factors. Despite the challenges, we delivered as promised and finished the project on time.
Starting in November 2023, we began procuring the steel for the five jetty modules: two pipe bridges, the main platform, an escape bridge, and a davit platform. We also procured the foundation piles and dolphins, piping systems, valves, and all key equipment, such as the loading arm, cranes, davit, firefighting monitors, wastewater tank, and control systems.
Steel prefabrication started in March 2024, followed by piping prefabrication in May 2024. At the same time, in May 2024, we started the demolition of the old jetty and installed the new foundation piles on-site in Germany.
In June, we started assembling the five modules at our yard in Vlaardingen and at our subcontractor’s yard in Werkendam. This off-site approach allowed us to complete a large portion of the work in the Netherlands and minimize time and complexity at the client site.
Once ready, we transported the modules via the Rhine to Godorf harbor. A crane vessel placed them on their foundations. On-site, we handled final piping and E&I connections, installed all remaining equipment, and supported the client during testing and commissioning.
Despite time pressure and challenging conditions, J. de Jonge delivered the jetty safely, on time, and within budget. The client was satisfied, with only a small number of punch items and without major quality issues. Problems were solved quickly and professionally. Both the client and J. de Jonge look back on a strong collaboration and a successful project.
