E-Ship 1

The E -Ship 1 in the port of Emden

Germanischer Lloyd 100 A5 E3

IMO no. 9417141

The E -Ship 1 is a cargo ship, which in addition has not only a diesel drive via a drive by Flettner rotors, ie, a rotor ship. It was commissioned in 2006 by the Enercon of Aurich in the Lindenau -Werft in Kiel and completed in 2010 at the Cassens Shipyard in Emden. It is designed for the transport of Enercon wind turbines. According to the operator, the fuel economy is through the Flettner rotors and other optimizations up to 25 percent.

History

The hull was built as Lindenau 285 of the Lindenau -Werft in Kiel. The launch took place on August 2, 2008. Originally, the ship should be delivered in the first half of 2009. The insolvency of the Lindenau -Werft could there not be completed, but was transferred in November 2008 to Cassens shipyard to Emden. There the steel construction was finished in January 2010, and the ship was towed into the dock of the North Sea stations, where recent work has been carried out on the underwater hull. In April 2010, the ship returned to the Cassens shipyard where the other equipment carried.

Since 1 June 2010, the ship is officially called E-Ship 1 The first test drive on the North Sea took place on 6 July 2010. The test drives were accompanied by the Germanischer Lloyd classification society than in the southern North Sea instead. In the summer of 2010, the E-Ship 1 was put into service. The maiden voyage was to Ireland. In October 2010, on a trip in the Mediterranean, the savings in fuel consumption should be determined.

After problems with the Mitsubishi diesel generators, the ship was in Emden since 18 January 2013. The replacement of diesel generators could be carried out from November 2013 only because the back-up generators had first to be made ​​..

Construction

The new building, the bridge is on the back is designed as an intermediate -decker with three decks and two standing on the port side cranes of 90 t payload, with a long boom and a rear ramp, so a LoRo ship.

The ship has a length of 130.42 m and a width of 22.5 m has a shallow draft of max. 9.3 m and a survey of 12,968 GT with a carrying capacity of 10,000 dwt. It is equipped with powerful maneuvering at bow and stern, and obtains the GL ice class E3.

Drive and machinery

In the basic design of the ship a number were realized by advanced engineering solutions, one of which falls the drive concept most evident. The freighter was initially evaluated by a diesel -electric propulsion with seven Mitsubishi marine diesel engines, the exhaust gases were passed through a waste heat recovery boiler connected to a steam turbine from Siemens STE and additionally by four, developed by Enercon Flettner rotors with a height of 27 m and a diameter of 4 m driven. The aim was to fuel savings of 30-40% on a ride of 16 knots. Due to technical problems the engines were replaced in 2013 by a total of seven Caterpillar engines with 6.3 MW total capacity.

The rear stern tube nut as a repository for the ship's propeller was designed in collaboration with the cast steel and cast in Groeditz Groeditz on 19 December 2007. For cold supply for the air conditioning, an absorption system is provided for the first time on a cargo ship, the generated with the help of adequate existing waste heat cold.

Use of new materials and, in collaboration with the Hamburg Ship Model Basin optimized hull provide further savings.

Load in the room and on the deck

Further savings hoped for Enercon, because so far caused disproportionate expenditure as lashing and not usable space for the transport of wind turbines chartered cargo space for these special items. The tailored construction, however, is by special, as " cartridges" designated caddies on the one hand the loading and stowage of plant components cheaper, but on the other hand, for the cost optimization of the return freight of third parties can accept easily.
