Heerema Starts Construction of TenneT’s HelWin Beta Platform

Heerema Start Construction of TenneT's HelWin Beta Platform

Today the construction of the 690MW platform for TenneT’s offshore grid connection project HelWin2 officially started. The steel cutting ceremony took place at the yard of Heerema Fabrication Group in Zwijndrecht (the Netherlands), where the topsides of the platform will be built. The jacket and bridge will be constructed at the Vlissingen yard of HFG in the Netherlands.

The HelWin beta platform will be built for electricity grid operator TenneT by the Heerema Fabrication Group and is an EPCI contract (Engineering, Procurement, Construction and Installation) between Siemens and Heerema Fabrication Group. The platform has been developed jointly by Heerema Fabrication Group and Siemens, main contractor for the HelWin2 project.

The platform will connect a large wind farm cluster in the German sector of the North Sea. It will receive alternating current from wind farms, and convert it into direct current before transporting it onshore via subsea cables. The 98 by 42 meter steel structure of the platform topsides will be more than 27 meters tall and weighs over 10,000 metric tonnes.

During 2013 an average of 450 people will be working on the Heerema Zwijndrecht and Vlissingen fabrication sites, excluding engineering and additional supply chain jobs.

The platform will be ready for sail away from the Heerema yard by mid 2014 for installation during the 3rd quarter of 2014.

HelWin2 project

The HelWin2 project establishes a 690 Megawatt grid connection for wind farms close to Heligoland. This TenneT project is the third connection in the eastern North Sea.

The first offshore wind farm that will be connected is Amrumbank West. The grid connection runs 45 kilometers across land from the converter station in Büttel to the coast, and from the landing point in Büsum a further 85 kilometers directly to the offshore converter station. The connection should be completed by spring 2015.

UTC 2017

The subsea industry has, as all other parts of the oil & gas industry, been seriously rattled by the most severe downturn in the hydrocarbon energy era. However, the realization of what hit us and actions to be taken to sustain a healthy and profitable future is still on-going – unfortunately with thousands of colleagues paying the price by losing their job as one of the most severe consequences. At this time, there are signs that we have reached bottom in terms of most industry indicators, but few experts expect a sharp recovery. Many seem to believe that a slow recovery is what the industry needs in order to avoid an unsustainable capacity build-up, as seen in the period after the financial crisis. Considering the uncertainty of what the future will bring, this year’s UTC Program Committee have decided to challenge all of us to present ideas, experiences, technological innovations, business models and execution models for how to shape our subsea future and explain how and why subsea is the future.
UTC welcomes abstracts based on the topics listed below. If selected, please consider writing a paper in addition to the UTC presentation. From 2017, UTC papers will be published in an international database.
