Template for monster platform challenges Heerema. ESAB low-hydrogen consumable technology crucial in safe and productive welding. ALFRED VAN AARTSEN, HEEREMA VLISSINGEN B.V., THE NETHERLANDS AND ERIC DE MAN, ESAB NEDERLAND B.V., AMERSFOORT, THE NETHERLANDS. Thicker and heavier, and with sharper tolerances than ever before – this was in essence the challenge Heerema Vlissingen faced in the construction of the template for the Tombua Landana oil and gas platform. The answer was found in smart logistics and precision work, supported by proven welding solutions. (See page 14 for a description of the Figure 1. The tower base template TBT (grey), the tower bottom section TBS (brown) and the foundation piles. Tombua Landana project). Acknowledgement We thank Heerema Production Manager, Harm Sanstra, for facilitating our visits to the Vlissingen yard. Heerema Fabrication Group (HFG) Heerema is a name that requires little explanation – especially not for Svetsaren readers in the oil and gas industry. It is one of the bigger, globally operating players in the engineering and fabrication of large and complex structures for the oil and gas industry. It has been active in the offshore industry ever since oil and gas were discovered in the North Sea in the early 1960’s and enjoys a reputation for state-of-the-art engineering, fabrication and project management. HFG has yards in the Netherlands (Vlissingen and Zwijndrecht) and in the United Kingdom Svetsaren no. 1 - 2008 - 7
