The Explorer is a SWASH pilot tender (Small Waterplane Area Single Hull) that is used by the pilotage association for pilot changes on the Elbe near Brunsbüttel .
description
The ship was built under construction number 6496 by Abeking & Rasmussen in Lemwerder . The keel was laid on December 1, 2011, the launch on December 10, 2012. It was completed on March 4, 2013.
The ship was built by Abeking & Rasmussen for their own account and initially chartered to the Federal Ministry of Transport and Digital Infrastructure for testing. The Federal Ministry bought the ship on April 5, 2017. It is operated by the Lotsbetriebsverein eV (Lotsbetriebsverein eV) branch in Cuxhaven and used in the Lotsveretzbetrieb outside Brunsbüttel.
The ship is based on the SWATH @ A&R concept. However, since this is relatively expensive due to the two hulls , in each of which a drive system is housed, and the ships must have a minimum size due to the space required for the drive, the shipyard developed a monohull concept. Unlike the SWATH ships, the SWASH construction has a hull with two stabilizing floats attached to the sides of the platform placed on the hull. Due to the vertical side walls, it is possible to safely climb over the pilot when walking alongside .
The ship is driven by two people. There is space for eight more people on board. The fuel tanks hold 5 tons of fuel. The range of the ship is about 300 to 400 nautical miles , depending on the speed .
Technical specifications
The drive of the vessel by a hybrid drive consisting of an MTU - the diesel engine (type: 10V2000 M72) and a Siemens - electric motor is. The MTU diesel engine has an output of 900 kW and acts on a controllable pitch propeller via a reduction gear . The ship can thus reach around 17 knots . In slow travel mode and at frequently changing speeds, the ship can also be powered by the Siemens electric motor. With the electric motor, the ship can reach around 6 knots.
A generator is coupled to the drive motor . The engine can run with constant power and excess energy can be used to drive the generator to generate electricity. Another generator is driven by a Volvo Penta diesel engine (type: D5A-B TA). The system is based on the ELFA system originally developed by Siemens for city buses. The drive system, consisting of the drive motor and generator as well as the electric motor, is housed in the trunk tube.
The ship is equipped with an electrically powered bow thruster .
