Concordia Damen is working closely with several industry leaders on the development and construction of two groundbreaking vessels, Rotra Futura and Rotra Horizon, purpose-built for the offshore wind sector. These innovative coasters are tailored for the transport of increasingly large wind turbine components, and the Jiangsu Zhenjiang Shipyard in China is set to complete construction by 2025, with Amasus Shipping as their future operator.
In a unique alliance with deugro Danmark, Siemens Gamesa, DEKC Maritime, and Amasus Shipping, Concordia Damen has designed these vessels with a focus on efficiency, safety, and adaptability. Through meticulous mapping of the offshore wind industry’s logistical demands, this partnership has shaped a vessel concept that aligns with sustainability goals while offering practical solutions for the logistical challenges presented by offshore wind turbines. A long-term charter between Siemens Gamesa and Amasus Shipping further underscores the commitment to a reliable supply chain within this rapidly growing energy sector.
The Rotra Futura and Rotra Horizon build on the success of Concordia Damen’s previous vessels, Rotra Mare and Rotra Vente, both of which have been in service since 2016. However, the new vessels go a step further, accommodating the latest, larger wind turbine components. With a length of 167.6 meters and width of 26 meters, both vessels feature a Roll-On/Roll-Off (RO/RO) system, a unique portal loading setup, and three Liebherr cranes for secure and efficient handling of oversized turbine blades. This enhanced flexibility allows turbine blades to be stacked in three tiers, maximizing the vessels’ cargo capacity without sacrificing loading versatility or operational safety.
Strategically designed for optimal performance, the Rotra Futura and Rotra Horizon also boast front-positioned wheelhouses and crew accommodations, which help maximize cargo space while ensuring clear visibility. As the demand for larger offshore wind turbines rises, these vessels meet industry requirements by supporting larger equipment without hindering handling efficiency.
Concordia Damen has also prioritized fuel efficiency and sustainability in these vessels’ design. The ships feature an aerodynamic, hydro-optimized hull, combined with a specialized low-resistance coating, which reduces fuel consumption. A Wärtsilä main engine powers the vessels, delivering 15 percent lower fuel consumption and reduced CO₂ emissions. Compliant with IMO Tier 3 standards, the vessels incorporate hybrid propulsion and a waste heat recovery system, further enhancing energy efficiency and minimizing their environmental impact.
Rotra Futura and Rotra Horizon exemplify the forward-thinking approach necessary to meet the evolving needs of the offshore wind industry. Their design aligns with Concordia Damen’s commitment to advancing sustainable maritime logistics, strengthening the foundation for future growth in renewable energy.
Once completed and delivered, these vessels are expected to play a crucial role in advancing global offshore wind projects, offering a more sustainable path for the logistics of wind energy development.
