deugro Danmark revolutionizes offshore wind transport with new vessels

deugro Danmark, in partnership with Siemens Gamesa and Amasus Offshore B.V., is set to introduce two groundbreaking vessels designed specifically for the transportation of offshore wind turbine components.

The Rotra Futura and Rotra Horizon, scheduled for delivery in 2025, represent a significant advancement in the sector, accommodating the growing size and weight of next-generation wind turbine components while optimizing cargo intake and operational flexibility.

The concept builds upon the success of the existing Rotra concept, which includes the Rotra Mare and Rotra Vente vessels. Since its introduction in 2016, this tailor-made concept has proven highly effective in reducing risk, loading time, and costs by utilizing a unique roll-on/roll-off (RO/RO) and gantry system for transporting offshore wind turbine components.

Measuring 167.6 x 26 meters, the new vessels feature a forward-placed deckhouse and accommodation to ensure optimal cargo intake without line-of-sight limitations. Equipped with a stern RO/RO ramp, three Liebherr cranes, and a unique gantry system, the vessels offer exceptional flexibility in cargo composition and loading methods, allowing for three-tier stowage of blades.

Reducing carbon footprint

In addition to enhancing operational capabilities, the design of the vessels prioritizes reducing the overall carbon footprint. Extensive efforts have been made to minimize energy consumption, including the implementation of an aerodynamically and hydro-optimized hull shape, a low-resistance special hull coating, and a state-of-the-art Wärtsilä diesel engine with 15% lower consumption and carbon footprint compared to current standards. The vessels also feature an efficient power train with a hybrid propulsion system and an exhaust gas cleaning system meeting the highest IMO Tier 3 standards, along with waste heat recovery systems.

Hans Henrik Groen, Branch Manager and Managing Director of deugro Danmark, emphasizes the importance of reducing the carbon footprint in the offshore wind industry, recognizing it as a key factor in future success. Thomas Mortensen, Head of Offshore Project Transportation at Siemens Gamesa, highlights the strategic partnership and expansion of cooperation, expressing anticipation for the arrival of these two new vessels, which will further strengthen their ability to execute and deliver on operational expectations.

The joint effort between deugro Danmark, Siemens Gamesa, and Amasus Offshore B.V. showcases their commitment to innovation and sustainability in the offshore wind industry. The selection of deugro Danmark as the preferred supplier for this groundbreaking concept demonstrates the success of their past collaborations and the confidence placed in their ability to drive progress.

Christian Johansen, Global Commodity Manager for Ports & Transportation in Siemens Gamesa’s offshore business unit, emphasizes the importance of securing the ability to execute projects safely, on time, and cost-effectively, especially given the company’s record order backlog and the increasing size and complexity of wind turbine components.

The construction of the two vessels will take place at Jiangsu Zhenjiang Shipyard in China, with delivery scheduled for the spring and summer of 2025.
