deugro Danmark and its partners Siemens Gamesa and Amasus Offshore B.V. will bring two newly designed vessels—customized for transporting offshore wind turbine components—to the market.
Siemens Gamesa and deugro have entered into a long-term charter agreement for these newbuild vessels, Rotra Futura and Rotra Horizon, which will be delivered in 2025. The new concept builds upon the existing tailor-made and award-winning Rotra concept with the
Rotra Mare and Rotra Vente vessels.
Since 2016, this concept has proven to be very successful— reducing risk, loading time and costs by utilizing a unique RO/RO and gantry system when transporting offshore wind turbine components.
The new vessels have been designed to accommodate the increasing size and weight of the next generations of offshore wind turbine components and, at the same time, to ensure best-in-class cargo intake and operational flexibility.
Rotra Futura and Rotra Horizon will measure 167.6 x 26 meters, with the deckhouse and
accommodation placed forward to ensure optimal cargo intake without any line-of-sight limitations.
The vessels will be fitted with a stern RO/RO ramp, three Liebherr cranes and a unique gantry system, allowing stowage of blades in three tiers, providing excellent flexibility in cargo composition and method of loading.
Reducing the overall carbon footprint was one of the main drivers in the design phase and conceptual development of these new vessels.
Energy consumption has been reduced thanks to an aerodynamically and hydro-optimized hull shape, a low-resistance special hull coating and a stateof-the-art Wärtsilä diesel engine with a 15% lower consumption and carbon footprint compared to today’s standards.
In addition, an efficient power train with hybrid propulsion system and an exhaust gas cleaning system meeting the highest IMO Tier 3 standards have been integrated into the new vessels, with special attention also being paid to waste heat recovery.
