The Boknafjord is a double-ended ferry operated by the Norwegian shipping company Fjord1 .
history
The ferry was ordered on June 21, 2010 and built under construction number 79 on the Norwegian Fiskerstrand Verft. The hull was supplied by the Western Baltija Shipbuilding yard in Klaipėda . It was built there under construction number 09. The ship design comes from the Norwegian marine architecture office Multi Maritime and is called "MM 120 FD LNG".
The keel of the ferry was laid on November 24, 2010, and the launch on July 11, 2011. The ship was christened on December 14, 2011. The godmother was then Minister of Transport Magnhild Meltveit Kleppa . The ship was completed on December 29, 2011.
The ferry runs together with the externally very similar ferries Stavangerfjord and Mastrafjord between Arsvågen on the island of Vestre Bokn and Mortavika on the island of Rennesøy. It is named after the fjord of the same name on which it operates.
Technical specifications
The ferry is powered by gas. The drive consists of four propeller pods with pull propellers , two of which are installed at each end of the ferry. The propeller pods from Kongsberg Maritime are each driven by an ABB electric motor with an output of 2200 kW . Four generator sets from Bergen Engines are available for power generation. Three generators are of nine-cylinder - gas engines of the type C26: 33L-9 is driven, each with 2310 kW power, one of a diesel engine of the type C25: 33L-9 kW 2850 performance. The diesel generator primarily serves as a security. During daytime operation, the energy required for propulsion and on-board operation is provided by the three gas generators. In addition, an emergency generator powered by a Scania DI16 diesel engine was installed.
Two tanks with a capacity of 125 m³ each are available for the liquefied natural gas . There is a tank at each end of the ferry. The tank capacity of the diesel tank is 49 m³.
The ship's propulsion system is redundant so that if one engine room fails, the ship can continue to operate via the second engine room.
The ferry has two vehicle decks. The vehicle deck on the main deck is 120 meters long. Five lanes are available for almost the entire length. Only three lanes are available at both ends of the ships (the ship tapers a little here). The main deck is open to the top at both ends. It is closed to the front and back by a visor that can be opened upwards. Below the main deck there is another vehicle deck with six lanes accessible via ramps. Trucks, buses and other higher vehicles can also be transported on the main deck. The usable height on the deck below allows only the transport of cars.
In the middle area of the ships, the main deck is covered by the superstructures with four decks. In the superstructures on deck 5 there are two lounges for the passengers and a self-service restaurant with kitchen in between. This configuration enables faster service to the passengers. There are also two open deck areas on this deck.
Most of the facilities for the ship's crew are located on deck 6 . The ferry is equipped with 16 cabins for crew members, some of which are designed as single and some as double cabins. The ship's crew lives on board and changes every fortnight. The kitchen and other service staff are only on board during the operating hours of the ferry.
The passenger capacity is given as 589 people. The total capacity of the ferry is 600 people. The ferry is equipped with two ship evacuation systems. There are also three life rafts available.
