Amasus Shipping has launched its offshore wind ro-ro vessel, Rotra Futura, at Jiangsu Zhenjiang Shipyard in China.
Along with Rotra Horizon, the vessels have been specifically designed for the transport of large wind turbine components, with Rotra Futura expected to be delivered in 2025.
As part of a partnership, Amasus received logistical support and insight from Siemens Gamesa and deugro, while counting on DEKC Maritime and Concordia Damen for shipbuilding matters.
Both Rotra Futura and Rotra Horizon build on the previous vessels in the Rotra concept – the Rotra Mare and Rotra Vente.
With a ramp allowing for larger loads, the vessels are equipped with three Liebherr cranes which means that turbine blades can be stored in three tiers.
Measuring 167.6 m x 26 m, and with both the wheelhouse and accommodation located at the front of the ship, the modernised Rotra design maximises cargo capacity while ensuring optimal loading without impacting visibility.
“The aerodynamic and hydro-optimised hull design, combined with a special low-resistance coating, contributes to lower fuel consumption,” said Chris Kornet, managing director of Concordia Damen. “Furthermore, the vessels are equipped with an advanced Wärtsilä main engine, which consumes 15 percent less fuel and has a smaller CO2 emission footprint than current standards.”
The vessels are fitted with a hybrid propulsion system that complies with the highest International Maritime Organization (IMO) Tier 3 standards. They also have an efficient waste heat recovery system, further enhancing energy savings.
Last month, HLPFI reported that Amasus had signed a second wind power contract with Spain’s bound4blue.
