At Heerema Vlissingen, one of the fabrication facilities of Heerema Fabrication Group (HFG), the HelWin bèta jacket was completed and sailed on Friday to its offshore location in the German sector of the North Sea.
The total engineering, procurement and construction activities, including seafastening operations, of the HelWin jacket provided 175,000 man hours direct and indirect employment at HFG Engineering and the Heerema Vlissingen yard without any LTI (Lost Time Incidents).
Heerema Marine Contractors will perform the offshore transportation and installation by its SSCV (Semi-Submersible Construction Vessel) ‘Thialf’.
In the meantime HFG’s fabrication facility Heerema Zwijndrecht is working on the final construction phase of the 10,200 t HelWin bèta HVDC (High Voltage Direct Current) topside, due for completion in the summer of 2014.
Koos-Jan van Brouwershaven, CEO of Heerema Fabrication Group , says: “ Thanks to our experienced and highly skilled workforce we were able to demonstrate our proven offshore experience to reach this second important project milestone and to deliver the jacket on schedule. The EPC(I) contract with Siemens on HeWin bèta project shows our ability to manage such a challenging and complicated project through all the phases such as engineering, procurement, fabrication and installation.”
The jacket is part of the HelWin bèta HVDC platform, which is one of the main components of the TenneT DC offshore grid connection ‘HelWin2’. The connection with a capacity of 690 MW will connect a large wind farm cluster in the German sector of the North Sea.
