- KM69-M2 magnetic compass.
Stability and seaworthiness
The initial transverse metacentric height of the boat with standard displacement is about 5 m.
The sea-going capacities of the boat provide:
- use of weapons in sea point up to 4 inclusive (wave height of 2 m with 3% probability) with no restrictions on course at a speed attained at maximum allowable rpm of the main engines.
- safe stay in sea point up to 5 inclusive (wave height of up to 3.5 m with 3% probability) at a slow speed of 10-12 knots.
Main propulsion plant
Its twin-shaft plant consists of two M533 main diesel engines, each driving a fixed-pitch propeller.
Three centrifugal fans are used to pump air into a cavity, with two of them driven by hydraulic motors operating from hydraulic pumps attached to the main diesel engines, while the third one is driven by an electric motor.
Electric power (3-phase 380VAC, 50Hz) is provided by two DGR75M2/1500-1 diesel generators. There are also two EKPA-2/150 electric compressors.
Control of the main engines, their auxiliaries and diesel generators is provided by a shipborne automated monitoring and control system located in the wheelhouse.
