11. SHORE connection controller
11.1 SHORE connection controller overview
11.1.1 Description
A SHORE connection controller controls and protects the system and the shore connection breaker when a shore connection is
connected. When the shore connection is in use, it is normally the ship's only power source. However, the gensets may run in
parallel with the shore connection for a limited time.
11.1.2 Applications
There is no restriction on the number of SHORE connection controllers.

11.1.3 SHORE connection controller functions
Functions
Pre-programmed
sequences
• Shore connection breaker open sequence (with or without de-loading)
• Shore connection breaker close sequence (with synchronisation)
• Blackout close
• Load transfer from one shore connection to another (using gensets)
• Load transfer from the shore connection to a shaft generator (using gensets)
Load control
• Load transfer between shore connection and genset(s)
• Base load possible from shore connection; genset(s) load responds to demand fluctuations
• Connect multiple shore connections from the same source (configurable)
• Connect multiple ship-to-ship supplies (configurable)
• Shore connection close load
• Sensitive shore connection (overlap)
Counters
• Display unit counters, to edit or reset
◦ Shore connection breaker operations and trips
◦ Power export (active and reactive) (to the shore connection)
◦ Power import (active and reactive) (to the ship busbar)
◦ External breaker operations
• Energy counters with configurable digital outputs (for external counters)
