Connecting the ship’s network to helicopter equipment
The ship’s network and the helicopter’s loads use different electrical supply parameters. A starting power unit takes energy from the ship’s network and provides the required output modes. Selection considers both aviation requirements and integration into the vessel’s power-supply system.
System specifications
The VID catalogue describes a 40 kW starting power unit. Its input is a three-phase 400 V, 50 Hz supply. Outputs of 200 V at 400 Hz and 270 V DC are provided for onboard loads. The output arrangement and use are determined by the circuit of the particular project.
Engine starting and storage charging
The system performs two related tasks: supplying power during engine starting and charging onboard storage devices. A technical specification should distinguish these modes and describe their sequence, duration and connection requirements. Nominal power alone does not replace coordination of operating modes with the helicopter’s equipment.
Integration into the ship’s system
Design begins with circuit diagrams, supply-network data and load requirements. Unit location, connections, controls and condition monitoring are also agreed. This treats the starting system as part of the vessel’s electrical equipment, linked to specific operational scenarios.
Projects and engineering capabilities
The VID catalogue names SSK PJSC and the B. E. Butoma Shipyard JSC among customers in this field. The company’s capabilities include electrical circuit design, automation, in-house manufacture and load testing. Having these disciplines within one organisation helps coordinate equipment design, controls and manufacture.
Preparing requirements for a new unit
A new system requires the helicopter type and load data, ship-network parameters, operating modes and installation conditions to be defined. These inputs determine the unit configuration and verification requirements. The VID catalogue presents the wider range of marine electrical equipment.
