Trelleborg Marine and Infrastructure's newly launched advanced sealing system, IRIS, for Airtight Platforms (ATP), drew significant attention at WindEurope 2025 held in Copenhagen, Denmark, with industry leaders impressed by its innovative design alongside its potential to significantly reduce costs associated with offshore wind foundations.

The new seal eliminates the need for welded steel landing rings traditionally used in monopiles (MPs) and Transition Pieces (TPs), providing an effective solution to lower Levelized Cost of Energy (LCOE) for offshore wind projects, a crucial metric for developers seeking to maximize their return on investment.

Richard Hepworth, Business Unit President at Trelleborg Marine & Infrastructure, stated, “At Trelleborg, we recognize the challenges facing the offshore wind industry and are committed to driving its sustainable, long-term growth in every aspect while ensuring economic viability. Our new product exemplifies this commitment, providing a long-lasting and reliable solution without compromising on performance.”

Key advantages of the IRIS include significant reductions in costs associated with primary steel, welding, and engineering, alongside lower maintenance, and operational expenses. Its streamlined design also advances ease of installation, saving both time and resources. 

The IRIS represents a step forward in offshore wind foundation seal technology, aligning with the global push for more efficient and sustainable solutions. By addressing key cost and operational challenges, Trelleborg aims to support the rapid growth of the offshore wind sector while enabling developers to maximize their return on investment.
