The Ostfriesland is a combined car ferry and passenger ferry operated by Reederei AG Ems , which was converted into the first LNG ship under the German flag in 2014 . It completed its maiden voyage in natural gas operation on June 17, 2015 and operates mainly on the connection between Emden and Borkum . Occasionally the ferry is also used in traffic to Eemshaven . The ship transports people, goods and vehicles.
General
The Ostfriesland was built under construction number 186 at the Martin Jansen GmbH & Co. KG shipyard and machine factory in Leer. The keel of the ship was laid on December 22, 1983, the launch took place on January 12, 1985. Completion took place in April 1985.
Until 2014, the ship was powered by two MaK 6 M 332 marine diesel engines with an output of 1,000 kW each. In 2014 it was converted to a combined LNG and diesel drive with two multi-fuel engines (dual-fuel 6L20 DF) from Wärtsilä . With this LNG ship, the " chicken and egg problem " will be resolved, as it was previously said that LNG bunker stations will only be set up when there are ships in Germany that bunker LNG.
The sister ship of the Ostfriesland is the Münsterland .
Between 1960 and 1969 and between 1970 and 1981 two other ships under the same name sailed on the same route.
Reconstruction of the ferry 2014/2015
From October 21, 2013, the new aft section for East Frisia was built at the Brenn- und Verformtechnik (BVT) shipyard in Bremen-Vegesack. The ferry was still in service at the time. In 2014 she received a new, larger aft section, which also includes a new drive. The date for the wedding of the sections was set for autumn 2014 so that the ferry could continue to operate during the 2014 season.
Since 2015, the ferry can also run on liquefied petroleum gas ( LNG ). The conversion, which cost around 13 million euros, made the ship around 15 meters longer, which in addition to the loading capacity also increased the sundeck. Due to the complexity of the conversion, the re-commissioning of the ferry was delayed until mid-June 2015. The conversion to LNG propulsion was funded by the EU with EUR 3.07 million . During this reconstruction, the bridge, the management and passenger facilities were largely renewed and modernized. This created a contemporary ferry with today's infrastructure.
Repowering
Two new dual-fuel diesel engines from Wärtsilä have been installed, each of which acts on a generator to generate electricity, which operates at a nominal frequency of 60 Hz. Two Mitsubishi gas engines, which work as pure gasoline engines, serve as auxiliary engines. This means that both the main and auxiliary motors are used purely for generating electricity and can be used flexibly for driving and auxiliary operations as well as hotel operations with a frequency of 50 Hz. Two Schottel rudder propellers, electrically driven by converters, provide propulsion for the ship.
