Thanks for the pic. It is the powerplant choice that I find interesting, electric drive for cruise speeds with power coming from the ships power grid, ala DD(X), it makes the ship a good contender for future dirested energy weapons a well. Norway is to be congradulated on it's forward thinking. This may be of interst as well. this within a 132m hull lenght.
"An alternative Integrated Weapon System is also offered based on Lockheed Martin's AEGIS Combat System, designed around the multifunction phased array radar Spy-1F"
"The program comprises delivery of 5 multipurpose frigates to Royal Norwegian Navy. Each frigate will be equipped with one medium size organic helicopter. The delivery schedule reads one new frigate each year from 2005
The BAZAN NF project is a 130 m long monohull antisubmarine frigate, with a displacement of 4,600 t, a maximum transit speed of 27 knots, steel hull and superstructure, a CODLAG propulsion plant, an electric plant working in parallel or split mode, provided with helicopter and medical facilities, excellent seakeeping characteristics and enhanced survivability features, with special emphasis on minimising the underwater signature to obtain the most feasible silent frigate. Special emphasis has been paid in the design to ship automation, human factors, ship supportability, life cycle cost and the use of commercial off the shelf equipment, which have been considered as leading factors in the design process.
The vessel is an antisubmarine frigate primarily designed to detect, identify, engage and attack hostile submarines, also provided with anti-air, anti-surface and electronic warfare capabilities, offering significant potential for non combat tasks in peace time, such us to conduct sovereignty tasks. The platform design has been established to accommodate the Combat System dimensional fit, which represents the envelope of the complete set of sensors, weapons and C3I elements required to fully satisfy the requirements stated by the Royal Norwegian Navy.
The hull lines, based on the results of the BAZAN´s own hydrodynamic research programmes, have proven excellent stability, seakeeping and manoeuvrability. Hull appendages and propellers will be designed for low hydrodynamic noise, based on F-100 frigate experience.
The project is a five deck concept ship, subdivided in thirteen watertight compartments and two superstructure blocks above the level 01, being both, ship´s hull and superstructure, of welded steel using hybrid structural concept, where a mix of commercial and naval practices are applied.
The propulsion plant is a CODLAG cross connected type, having one gas turbine of 22200 kW, two AC propulsion electric motors of 2500 kW each, one gears set and two shaftlines each one driving a fixed pitch propeller. The ship has two Main Engine Rooms, separated by a Central Auxiliary Machinery Room. Additionally, an Aft Diesel Generator Sets Room is located astern the Aft Main Engine Room.
The gas turbine is installed in the Forward Main Engine Room. The gears set, installed in the Central Auxiliary Machinery Room, consists of a cross connecting primary gear and two secondary gears, linked by elastic couplings, being each secondary gear fitted with a clutch and a thrust bearing. Finally, the propulsion electric motors, located in Aft Main Engine Room, are mounted directly on the propeller shafts. The motor speed control is carried out by frequency converters.
In the quiet sailing mode, up to 16 knots, the gas turbine and the gears set are disconnected, being the propulsion electric motors capable of driving the ship ahead up to the cruise speed. For boost propulsion, the gas turbine and the propulsion electric motors run together.
A retractable bow thruster for improving the ship manoeuvrability in confined areas has been provided. This equipment can be used as an auxiliary propulsion unit in case of emergency, when the main propulsion is damaged.
The Engine Rooms will be unmanned according with the DNV rules. During normal working conditions, the propulsion plant will be remotely operated via the Integrated Platform Management System (IPMS) from the Engine Control Room (ECR) or from the Bridge. Local control will also be possible from the machinery spaces.
The electrical plant will be capable of supplying the electric power required by the propulsion electric motors and all ship auxiliaries. The generators will supply electric power at 690 V, 60 Hz, 3 phases to two Main Switchboards, that supply power to the propulsion electric motors, specific ship auxiliaries and the Ship Service Distribution Main Switchboards through two 690/450 V transformers.
The electrical generating plant is composed of four main diesel generator sets, two of 3000 kW and other two of 1100 kW. Two main diesel generator sets, one of each size, are located in the Forward Main Engine Room and the other two are arranged in the Aft Diesel Generator Sets Room. These rooms are separated by two watertight compartments and one damage control zone . . . . ."
There is a lot more but the article is too long to paste here. Well worth a read.
