Stena has delivered its first E-Flexer ferry, Stena Estrid
The 215-m long, 3,100-lane m capacity Stena Estrid is the first in Stena Line’s new line of E-Flexers.
Five of these vessels are for Stena Line and additional vessels will be on long-term charter for other ferry operators.
Stena Estrid participated in sea trials to test the performance of the vessel including all the onboard systems such as the propulsion plants. The vessel is equipped with twin-screw Caterpillar marine propulsion drive trains with MPP 1410f propellers, shafts and packaged gearboxes.
The vessel has a maximum output of 12,600 kW and is equipped with a MaK 12 M 43 C engine. The main engines and propulsion packages for seven of the ropax series were supplied by Caterpillar Marine.
Stena Teknik project manager hydro dynamics, Per Wimby said “After a long period of optimisation and testing with CMH/Deltamarin, MARIN and Caterpillar we now see the final product, which is the most efficient ship in Stena’s history.”
The propulsion solution was a collaborative effort involving Deltamarin, Stena, Caterpillar and CMJ Shipyard (Weihai). The design has already drawn praise within the industry for its innovative deployment of permanent magnet technology Stena hopes will prove energy efficient.
Deltamarin managing director Janne Uotila said “One of the key principles of Deltamarin designs has always been energy efficiency. Nowadays, due to environmental reasons and stricter regulations even more so and this project is a good example of this,” adding “This is a great achievement and a benchmark for how close collaboration between all parties can lead to fantastic results.”
Stena Estrid completed sea trials in October and arrived in Holyhead, Ireland on 23 December. The vessel will undergo final preparations before starting service on the Holyhead to Dublin route in mid-January 2020.
