Extreme short delivery time for 15 Vopak storage tanks
How smart logistics reduced the project time to half

Today, Mercon finished the testing of 15 newly built storage tanks at the
Vopak terminal in Vlaardingen, where vegetable oils and biofuels are stored. The tanks were installed end of May in only six days time during a 24/7 operation. In these six days also the pipe bridges and walkways were installed.
In fact, the complete project duration was decreased substantially compared to a similar previous project.
Vopak issued a tender requesting to build nine smaller tanks (diam. 12.48, height 26m) off site and to build the remaining six larger tank (diam. 17.48, height 26m) on site. The 15 tanks have a total capacity together of approximately 66,000 cubic meters. The nine smaller tanks had to be equipped with a dome roof whereas the six larger tanks needed to be provided with a cone roof.
In its proposal, Mercon – with partner Peinemann – offered to build all tanks off site. In this way the building of the foundations for the tanks could start at the Vopak site while Mercon tanks at the yard in Dordrecht. Mercon especially arranged this yard for the Vopak project as it own two yards were fully engaged with other projects.
Leading to a considerable reduction of the project duration, this approach appealed to Vopak upon which they granted the project to Mercon.
Mercon‘s Managing Director Willem Griffioen is particularly proud that the tanks were completely prefabricated (including spiral heating, preservation and insulation), transported and installed in only eight months time. ”All piping bridges and walkways were prefabricated as well on the Dordrecht yard in this short time frame. At peak days the Mercon workforce of welders, painters and other craftsmen amounted to over 150 people. For our customer Vopak it was an advantage to not have all these people at their site.” Ralf van der Meij, Project Manager at Mercon adds that despite the short lead time, this project is also special because of the high technological features.
“For the insulation of the nine dome roofs and six cone roofs, a special and robust insulation system has been applied according to the latest CINI standards.”
