The type SF 1650 is a type of ferry boat built for the Swedish shipping company Destination Gotland , of which two units were built. The liquefied natural gas powered ferries operate between Oskarshamn and Nynäshamn on the Swedish mainland and Visby on Gotland .
history
The ship type was designed by the Danish ship architecture firm OSK-ShipTec. It is based on the type SF 1500 , of which two units were also built for the Destination Gotland shipping company. The first unit was ordered on June 23, 2014, the second unit on June 16, 2015. The ships were built at the Guangzhou Shipyard International Co. in Guangzhou , China , the same yard that had built the two SF 1500 ferries in 2003. The keel laying of both ships took place on December 10, 2015. The ships were due for delivery in 2017 and 2018. Completion was delayed, however, so that they were only delivered in December 2018 and December 2019. The type ship was put into service in March 2019. The construction costs of the two ships amounted to about 242 million US dollars .
description
The vessels are of four twelve-cylinder - dual-fuel diesel engines the engine manufacturer Wärtsilä : with a total of 46,800 (Type W12V50DF) kW power driven. The engines, which can be operated with diesel fuel or liquefied natural gas, act on two variable-pitch propellers via reduction gears . The ships are equipped with tanks for 570 m³ liquid gas and 400 m³ diesel fuel. The ship is operated with liquefied natural gas. In normal operation, the diesel fuel is only required to start the engines. Operation with liquefied natural gas reduces CO 2 emissions by around 20 percent compared to operation with diesel fuel, and sulfur dioxide emissions are reduced by around 99 percent. The use of liquefied biogas further reduces CO 2 emissions . Since May 2020, biogas has been added to the liquefied natural gas for the operation of Visborg on a test basis. In principle, operation with 100 percent biogas is possible.
Two shaft generators driven by the main engines and four generators driven by Wärtsilä dual fuel engines (type: 9L20DF) are available for generating electricity. Furthermore, an emergency generator powered by a Cummins engine (type: KTA50-D (M)) was installed. The ships are equipped with two electrically powered bow thrusters .
The ships have eleven decks. On deck 3 and deck 5 are the two vehicle decks with a total of 1745 lane meters . There are 870 gauge meters on the main deck (deck 3) and 875 gauge meters on the deck above (deck 5). The vehicle deck on the main deck is a continuous vehicle deck. It can be reached via the ship's own ramps at the bow and stern of the ships. The ramp at the bow is located behind a bow visor that can be opened from the side . There are three ramps available at the stern . The main deck can be reached via the middle ramp, and the vehicle deck above, which can be reached from the loading ramp via two ramps on board, via the two outer ramps. The usable height on the main deck is 4.95 meters, on the deck above 4.90 meters. The vehicle decks are interrupted in the middle by shafts for supply and disposal, elevators and stairwells.
Below the main deck are the engine room and other ship operating rooms as well as areas for the ship's crew . On the decks above the vehicle decks, the facilities for the passengers, further operating rooms and areas for the ship's crew as well as the bridge are housed. On decks 7 and 8 there are lounges with reclining chairs for the passengers in the front area. Behind it, on deck 7, there are, among other things, the entrances to the ship for pedestrians with the reception in the center, a self-service restaurant with an area with seating at tables, a cafeteria and other areas with loungers, including an area for families with small children. On deck 8 there is an area for passengers traveling with dogs and the passenger cabins behind the front lounge. A total of 1658 lounge chairs are available on the two decks. The self-service restaurant can seat 318 people. 98 cabins with a total of 222 beds are available on deck 8. On deck 8 there are open deck areas on both sides in the midship area, on deck 9 there are also open deck areas on both sides, and in the rear area of the deck there is also seating. Additional seating is located on the open deck area on deck 10, roughly in front of the middle area of the ships. This is partially covered. The bridge is located on deck 10 in the forward area of the ships. It is completely closed and extends a little over the width of the ship for a better overview. A helipad has been set up on deck 11 .
The ships can carry 1650 passengers. There is space for 80 crew members on board.
The range of the ships is around 6500 nautical miles . The ships are equipped with stabilizers . The hull of the ships is reinforced with ice ( ice class 1A).
