Stena Estrid, the initial of a brand-new generation of Stena Lina E-flexer RoPax vessels has actually shown up in Holyhead, Wales, following its distribution trip from the China Merchants Jinling Shipbuilding Weihai Shipyard in China.
The ship is the initial on a collection of 9 vessels, 5 for Stena Line as well as 4 that will certainly get on lasting charter for various other leading ferryboat drivers.
Stena Estrid is 215 meters long as well as has 3,100 lane-meters of capability.
FELINE MARINE PROPULSION SERVICE
She is geared up with 2 MaK 12 M 43 C primary engines as well as twin-screw Cat Marine Propulsion drive trains with MPP 1410f props, shafts as well as packaged transmissions.
Prior to distribution, Stena Estrid undertook extensive sea tests to evaluate the efficiency of the vessel consisting of all the onboard systems such as the propulsion strategies. On tests, she made considerable rate on 2 shaft lines in addition to on one shaft line with the various other in feathering setting.
Per Wimby, Project Manager, Hydrodynamics at Stena Teknik, commented “We did 18.5 knots using only one engine which exceeded our expectations.”
Caterpillar Marine functioned carefully with Stena’s newbuilding group to provide primary engines as well as propulsion bundles for Stena Estrid therefore much, 6 of her siblings in the brand-new collection.
It was identified that the MaK 12 M 43 C engine as well as feathering Cat Propulsion MPP 1410f props would certainly be the best suit for this vessel as well as the bundle was after that additional maximized in collective comprehensive simulations as well as design examination operate in order to press efficiency as high as feasible.
Wimby calls the end product “the most efficient ship in Stenas history.”
Janne Uotila, Managing Director of Deltamarin Ltd., claimed: “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. It is a result of close cooperation with Stena and Caterpillar in early stage of the development. All in all this is a great achievement and a benchmark for how close collaboration between all parties can lead to fantastic results.”
Mattias Hansson, Solutions Manager, Caterpillar Marine, claimed: “The open professional collaboration between all parties, from day 1 throughout the process, has been key to success.”
Caterpillar claims that, with an optimal result series of 12,600 kW (17,136 mhp), the MaK 12 M 43 C engine gives reputable power as well as efficiency. Developed to fulfill the needs of the cruise ship as well as ferryboat markets, this brand-new engine collection is the advancement right into a brand-new course of power. Coupled with the trademarked feathering Caterpillar controlled pitch props as well as the capacity to maximize the entire bundle under one vendor it produces an extremely reliable remedy for this vessel kind.
Compared to various other comparable ferryboats, claims Cat Marine, this vessel is extremely fuel-efficient as well as was, according to Maritime Research Institute Netherlands (MARIN). the very best design ever before checked in its course. The Cat Marine propulsion remedy flawlessly matches the engine qualities, vessel style, as well as is maximized in the versatile rate varies that Stena Estrid as well as her siblings are anticipated to run.
