Offshore power connected to the grid with Siemens; a further 4,500 MW have already been contracted
Siemens is the world’s leading partner for offshore wind farm grid connections. You too should rely on a trusting cooperation, professional and smooth execution – and unmatched experience.
Direct current transmission is more complex than AC technology – but offers some clear advantages with regard to efficiency.
One factor is the distance from the coast: the greater the distance, the more important it becomes to minimise the unavoidable physical power losses. This is where DC technology comes into its own.
Our standard solutions make things even easier, more transparent and up to 30 percent cheaper for you.
The new AC offshore grid connection solutions from Siemens rely on Offshore Transformer Modules, or OTM for short. The volume of offshore platforms can be reduced by up to 30 percent and weight savings of 33 percent are also possible with these standardised modules. The construction time can be cut by up to 20 percent – so that all in all, you will benefit from cost savings of 40 percent.
You too can profit from the eco-friendly design of the OTM from Siemens, the great flexibility of the supporting structure and the possibility of connecting turbines from various manufacturers. A Technology with advantages you can already use today.

Have your offshore oil and gas platform supplied with electricity from the shore – for three good reasons:
Firstly, generating electricity on land with a gas and steam cycle is not only very reliable but also nearly twice as efficient as a single gas turbine cycle on the platform. An advantage that you naturally don’t have to forego if you have to drill deeper in future or use your platform for alternative sources of energy.
Secondly, offshore generation produces noise and vibrations on the platform, quite apart from the safety aspects. And thirdly, the shore connection also benefits your carbon ecological footprint – because you reduce your CO2 consumption by almost 50%.
Good enough reasons to trust a highly available supply from the shore with a turnkey solution from Siemens – including three years with no maintenance required.
Every offshore wind farm has different natural and technical requirements. And only the right solution for its grid connection can guarantee long-term reliability and profitability. This is why it’s worth trusting in our experience from the outset.
Whether this be the early involvement of everyone concerned or the realisation of the design concept – a smooth process from the start is not a question of luck but of principles. This also includes feasibility studies and globally viable financing solutions. We define a value creation chain together with you that satisfies the requirements of both the project and the market. Thanks to our experience, you can be sure of a fast realisation of your project – with fewer and optimised interfaces.
Are you looking for a graphic, fact-based decision-making tool? Our digitisation solutions can help you with this.
We simulate the entire life cycle of your offshore platform and your grid connection, quickly make complex relationships understandable and show you how different decisions affect the project term and costs.
