Validating the proper functioning of electrical and control systems is critical for vessel owners, but the process can be complicated, time-consuming and risky. Technicians may need to fabricate temporary connections or gain access to precarious spaces. This introduces opportunities for human error and equipment failures that can lead to extended downtime. That`s why many owners are adopting Designed4Validation, a new approach that installs dedicated, marine-grade test points for critical systems like generators, switchboards and propulsion controls. Strategically locating type-approved connectors from recognized brands simplifies and streamlines validation work.

Validating current sensing equipment is critical for vessel owners to ensure safe operations. The most comprehensive method is primary injection testing. This involves using a specialized tool to inject a low-voltage, high-current signal directly into bus bars and cabling. You can think of primary injection like testing a smoke detector. When you press the "test" button, you are checking if the detector can communicate a fire. But by actually injecting smoke, you confirm the sensor can properly detect a real fire. Similarly, primary injection injects a small "fault" to validate the entire sensing and protection chain. Primary injection supports total system validation. It checks current transformers, Rogowski coils, wiring connections, and protective relays together. 

Demonstrate Single Fault Tolerance: Traditionally dynamic positioning vessels have operated in open bus configurations which reduces fault propagation paths between redundancy groups and subsequently reduces the risk of losing position. Modern strengthening of environmental and emissions standards have prompted vessel operators to move to closed bus configurations. While beneficial, closed bus configurations can lead to loss of DP capability if the power system is unable to ride through certain faults.
