What is a bus tie breaker?

A Bus Tie Breaker is an essential device used in electrical systems to connect or isolate individual sections of a switchboard. In maritime and offshore operations, particularly in vessels equipped with Dynamic Positioning (DP) systems, bus tie breakers play a critical role in ensuring power distribution reliability and flexibility.

What is a tie breaker?

A tie breaker is a type of circuit breaker that connects two sections of an electrical bus serving different power sources. They are commonly used to connect electrical systems to power sources and load circuits, as well as to protect people and equipment from overcurrents. In the context of maintenance, tie breakers offer significant advantages.

What are open bus-tie breakers?

This set-up focuses on the use of open bus-tie breakers to separate redundancy groups of gensets and thrusters in a power system configuration. These circuit breakers isolate faulty parts from healthy sections in the power system during faults, such as a short circuit or overload.

Are closed bus ties necessary for DP power systems?

A revised recommended practice issued by DNV can now facilitate the wider adoption of closed bus-ties for the connection of DP power systems in line with recent technological developments to support more robust and fuel-efficient systems. Class requirements for DP system redundancy have traditionally been set up for the safest mode of operation.
