Vopak Westpoort Tank Terminal
Commissioned by the Royal BAM Group, Stork Technical Services did the prefabrication of cross header modules, main headers and hook-up spools for the Vopak tank terminal at Amsterdam Westpoort. This project consisted of the prefabrication of 40 cross headers, 42 main headers and 380 hook-up spools. The scope also included pressure testing of the prefabricated cross headers, and assembly of the cross header modules. The load-out was done by crane. The modules were transported by barge from our facilities in the Antwerp harbour to Amsterdam Westpoort.
Stork Technical Services composed a dedicated project management organisation as an extension to our prefabrication shop. The PRINCE system gave us a detailed follow-up of quality and progress throughout the project. The welding quality and tolerances of the headers were secured by means of Submerged Arc Welding and our extensive welding expertise. On-site construction and the number of field man-hours were considerably reduced as a result of the prefabrication. This improved the overall safety figures since a maximum number of man-hours were spent in a less critical prefab environment. Build times were reduced and predictability was raised because the majority of the work was done under perfect in-shop conditions.
• Reduced build times
• Predictable project execution
• High quality module prefab
• Reduced number of field man-hours
• Reduced risk / increased safety
