Vopak Westpoort Tank Terminal

CHALLENGE

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.

SOLUTION

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.

RESULTS & BENEFITS

  • Reduced build times
  • Predictable project execution
  • High quality module prefab
  • Reduced number of field man-hours
  • Reduced risk / increased safety

TECHNICAL DETAILS

  • 40 cross headers (ca. 50 tons each including structural steel)
  • 42 main headers
  • 380 hook-up spools
  • Carbon steel pipes 
  • Galvanized structural steel
